Differential infiltration of macrophages and prostaglandin production by different uterine leiomyomas.

BACKGROUND: The association between uterine myoma and infertility is still controversial. The anatomical defect of endometrium by uterine fibroids could be a factor for reducing pregnancy rates and increasing miscarriage rates. However, pregnancy and implantation rates were found to be significantly lower in women with intramural myomas (IMMs), when there was no deformity of uterine cavity. This could be due to other biological factors such as increased accumulation of inflammatory cells within fibroid tissue and corresponding endometrium that might impair fertility. Therefore, we tried to investigate the pattern of macrophage (Mvarphi) accumulation in different uterine fibroids and the production of chemokine and prostaglandin (PG) by these tissues. METHODS: The selection criteria of uterine fibroids were based on the classification of European Society of Hysteroscopy. Biopsy specimens were collected from respective nodules and autologous endometrium of 20 women with submucosal myoma (SMM), 29 women with IMM and 18 women with subserosal myoma (SSM). CD68 immunoreactive Mvarphis were identified in these tissues by immunohistochemistry. A fraction of corresponding tissues were homogenized, and levels of monocyte chemotactic protein-1 (MCP-1) and PGF(2alpha) were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS: Mvarphi infiltration in the myoma nodule and corresponding endometrium of women with SMM and IMM was significantly higher than that of women with SSM or control women (P<0.01 and P<0.05, respectively). This tissue accumulation of inflammatory cells was independent of the sizes of the myoma nodules and phases of menstrual cycle. The tissue concentration of MCP-1 corresponded to increased Mvarphi infiltration and was significantly higher in women with SMM and IMM than that in women with SSM (P<0.05 for each). A positive correlation was observed between MCP-1 concentration and accumulated Mvarphi numbers in the endometrium of women with SMM and IMM but not in women with SSM. The tissue levels of PGF2alpha were also significantly higher in the nodule and corresponding endometrium of women with SMM and IMM than that in SSM or control women (P<0.05 for each). CONCLUSIONS: Higher production of MCP-1 could be responsible for the increased accumulation of Mvarphi in women with SMM and IMM. The augmented inflammatory reaction in endometrium and increased PGF2alpha levels might be detrimental to reproductive outcome in women with SMM or IMM.

Pre-operative gonadotrophin-releasing hormone agonist treatment in surgery for uterine leiomyomata.

To determine whether pre-operative treatment with gonadotrophin-releasing hormone (GnRH) analogue may have a beneficial effect on surgery outcome, 53 patients with symptomatic fibroid uteri awaiting myomectomy or transabdominal hysterectomy (TAH), were randomly divided into a study group (n = 29) and a control group (n = 24). The study group of patients were treated by an i.m. injection of D-Trp6 LHRH microcapsules at 2 months and 1 month prior to surgery. The control group had no pre-operative treatment. Haemoglobin concentration and oestradiol, follicle-stimulating hormone and luteinizing hormone concentrations were measured at 2 months and 1 month prior to surgery, and at surgery. The duration of surgery was shorter in the study group (49 versus 70 min in the hysterectomy group) and intra-operative blood loss was less (208 versus 309 ml in the hysterectomies and 320 versus 476 ml in the myomectomies). Pre-operative treatment with GnRH-agonists which induces shrinkage of the uterus and fibroids is therefore efficient in shortening the duration of surgery, and diminishing the intra-operative blood loss in surgery for fibroid uteri. Such pre-operative treatment is therefore a useful addition to surgery in cases with symptomatic fibroid uteri.

Non-surgical management of leiomyoma: impact on fertility.

PURPOSE OF REVIEW: This review is designed to discuss the literature, published from December 2002 to January 2004, on the non-surgical treatment of fibroid. All established and new modalities are reviewed, and all new developments in the field are discussed. The resulting impact on the treatment of infertility will also be evaluated. RECENT FINDINGS: In the past year important advances occurred in the medical treatment of uterine fibroids. It was found, in a large randomized trial, that preoperative treatment with gonadotropin-releasing hormone analogue did not improve surgical results or decrease blood loss. However, important strides were made in understanding the molecular biology of the effect of the hormone analogue on fibroids. Other medical therapies investigated include danazol, raloxifene, mifepristone, aromatase inhibitors, and the levonorgestrel-containing intrauterine device. Most promising in terms of long-term usage for reduction of size and symptoms appears to be the combination of gonadotropin-releasing hormone analogue and raloxifene, although selective progesterone receptor modulators may also achieve this aim. However, none avoid producing an anovulatory state that inhibits fertility, and none have been shown to enhance fertility following discontinuation. Uterine artery embolization is another non-surgical technique under intense investigation. The year's literature suggests that while results are comparable with hysterectomy in terms of complication rate and patient satisfaction, there may be important issues for women who wish to undergo the procedure and retain future fertility. Specifically, there is a significant rate of premature ovarian failure, as well as occasional damage to the endometrial vasculature with resulting atrophy and adhesion formation. Improvements in technique, in particular the use of larger and more spherical microspheres for embolization, may reduce these unwanted effects. However, few data exist regarding the course of pregnancy and outcome following embolization. SUMMARY: A number of non-surgical treatments exist for uterine fibroids, but none has been shown to be of value in the patient desiring future fertility. Myomectomy remains the standard of care for such women, and all other therapies should be designated experimental and limited to appropriate investigational studies.

The role of magnetic resonance imaging in minimal access surgery.

PURPOSE OF REVIEW: Magnetic resonance imaging is commonly used for gynaecological malignancies, but also is increasingly used for the investigation of benign gynaecological complaints. This review summarizes the current evidence regarding its use as an adjunct to minimal access surgery for endometriosis, adenomyosis, adhesions and fibroids. RECENT FINDINGS: Magnetic resonance imaging appears to be equal in efficacy to ultrasound for the diagnosis of both fibroids and endometriosis, and perhaps superior for the diagnosis of adenomyosis. It is extremely useful for the preoperative investigation of severe endometriosis, especially recto-vaginal disease. Milder endometriosis is, however, still difficult to diagnose by either ultrasound or magnetic resonance imaging. Magnetic resonance imaging can also be helpful for the detection of adhesions, pelvic collections, congenital defects and fibroids. It is also useful following fibroid embolization. SUMMARY: Currently, it is not cost-effective to use magnetic resonance imaging as the modality of first choice when investigating pelvic pain and or menstrual disorders. If preoperative patients are carefully selected, however, it can substantially reduce surgical morbidity by using it to diagnose severe endometriosis and adhesions which may lead to cost savings overall.

Prospective study of saline infusion sonohysterography in evaluation of perimenopausal and postmenopausal women with abnormal uterine bleeding.

AIM: To evaluate saline infusion sonohysterography as an investigative modality in abnormal uterine bleeding in perimenopausal and postmenopausal women. METHODS: Fifty-eight patients, 52 perimenopausal and six postmenopausal women, with abnormal uterine bleeding were selected from the department of Obstetrics and Gynecology of Shrimati Sucheta Kriplani Hospital. After complete work-ups, transvaginal examinations were performed followed by sonohysterographies. The sensitivity, specificity, positive predictive values and negative predictive values were calculated for transvaginal sonography (TVS) and saline infusion sonohysterography as compared with findings of hysteroscopy/hysterectomy. RESULTS: Saline infusion sonohysterography was performed in 56 cases. It could not be done in one perimenopausal and one postmenopausal woman. Cavity was normal in 41 perimenopausal and five postmenopausal women. Ten women displayed abnormalities. Two had submucosal fibroids, two had intramural fibroids, one had fibroid polyp, three had endometrial polyps and two patients had endometrial growths. We found that TVS missed three endometrial polyps and one endometrial growth and led to mislabeling two intramural fibroids as submucosal. On comparing the sonohysterographic findings with those of hysteroscopy or hysterectomy, one endometrial polyp and one endocervical polyp was missed on sonohysterography, and one false positive growth was observed on sonohysterography. The sensitivity, specificity, positive predictive value and the negative predictive value of TVS were 84.8%, 79%, 82.4% and 82%, respectively. The sensitivity, specificity, positive predictive value and the negative predictive value of saline infusion sonohysterography were 94.1%, 88.5%, 91.4% and 92%, respectively. CONCLUSION: Saline infusion sonohysterography is a safe, convenient, time conserving, cost effective, easily accessible and acceptable investigative modality. It definitely enhances the diagnostic potential of TVS in assessment of endometrium and intracavitary pathologies.

The binding of epidermal growth factor to the human uterus and leiomyomata in women rendered hypo-oestrogenic by continuous administration of an LHRH agonist.

The binding of epidermal growth factor (EGF) to human myometrium and leiomyomata was assessed in a group of women rendered hypo-oestrogenic with the LHRH agonist Zoladex (ICI 118630). The results were compared with those obtained with tissues from women with normal cycles. In normal women, the specific binding of radiolabelled [125I] EGF to both myometrial and fibroid homogenates did not vary during the menstrual cycle, but the specific binding of [125I] EGF to fibroid in women treated with LHRH agonist was significantly less than in the untreated group. Since the hypo-oestrogenic state induced by the agonist is associated with a decrease in fibroid size, the results suggest that the effect of oestrogen on fibroid tissue may partly be mediated by EGF.

The epidemiology of hysterectomy: findings in a large cohort study.

OBJECTIVE: To examine patterns of hysterectomy in the Oxford-Family Planning Association (Oxford-FPA) study in relation to age, parity, social class and calendar period (-1974, 1975-79. 1980-84, 1985-89). DESIGN: The Oxford-FPA study is a large scale prospective study of 17,032 women recruited from 1968-74 and still under observation. SETTING: Seventeen family planning centres throughout England and Scotland. SUBJECTS: At recruitment the 17,032 women were all white, British, married, aged 25-39 and willing to co-operate. In addition, they were using the pill or an intrauterine device or a diaphragm as their method of contraception. MAIN OUTCOME MEASURE: Hysterectomy rates per 1000 woman-years of observation in various subclasses of the data. RESULTS: Up to the end of 1989, 1885 (11.1%) of the 17,032 women in the study were known to have undergone hysterectomy. Fibroids were the most common cause followed closely by menstrual disturbances in the absence of fibroids (hereafter referred to as 'menstrual disturbances'). Social class had a modest influence on hysterectomy rates. Hysterectomy for fibroids, prolapse, endometriosis and 'other reasons' showed little trend with calendar period while hysterectomy for menstrual disturbances and for cancer showed a sharp increase with calendar time especially at ages 30-39. Hysterectomy generally tended to increase with age and showed a strong relation to parity; in particular, hysterectomy for fibroids fell with parity and hysterectomy for menstrual disturbances rose sharply with parity. Using lifetable methods, it was estimated that almost 20% of the women in the study would have had a hysterectomy by age 55. CONCLUSIONS: The results give insights into factors affecting hysterectomy rates. Of particular interest is the modest influence of social class, the strong influence of parity and the rise in rates with calendar time at ages 30-39 for those undergoing hysterectomy for menstrual disturbances or cancer, but since the cohort is not directly representative of the population, some caution is required in extrapolating these findings. The estimated hysterectomy rate of about 20% by age 55 is in line with other similar estimates for the United Kingdom.

Severe complications of hysterectomy: the VALUE study.

OBJECTIVES: To model the determinants of serious operative and post-operative complications of hysterectomy and their potential risk factors. DESIGN: A prospective cohort of women undergoing hysterectomies for benign indications in 1994/1995, with a six-week postsurgery follow up. POPULATION AND SETTING: A total of 37,512 women from 276 NHS and 145 private hospitals in England, Wales and Northern Ireland, originally recruited to compare the outcomes of endometrial destruction with those of hysterectomy. METHODS: Gynaecologists reported hysterectomies for non-malignant indications carried out during a 12-month period beginning in October 1994 and follow up data were obtained at outpatient follow up six weeks postsurgery. Odds ratios of severe complications by indication and method, adjusting for measured intrinsic risk factors, were calculated. MAIN OUTCOME MEASURES: Severe operative and post-operative complications. RESULTS: Severe operative complications occurred in 3%. The risk decreased with age and increased with greater parity and history of serious illness. Women with symptomatic fibroids (4.4%, 95% CI 3.9-4.9) experienced more complications than women with dysfunctional uterine bleeding (3.6%, 3.2-3.8), adjusted odds ratio (OR) = 1.3 (95% CI 1.1-1.6). Laparoscopic procedures (6.1%) doubled the risk of operative complications of abdominal hysterectomy (3.6%) (adjusted OR = 1.9, 1.5-2.5). Post-operative complications occurred in around 1% of women, with a slight decrease with increasing age, and the strongest risk factor was a history of operative complications. Relative to dysfunctional uterine bleeding (1.0%), a higher risk for fibroids (1.2%) persisted after adjustments (RR = 1.5, 1.1-2.0). Both vaginal (1.2%) and laparoscopic (1.7%) techniques had significantly higher adjusted risks than abdominal operations (0.9%), RR = 1.4 (1.0-1.9) and RR = 1.6 (1.0-2.7). There were no operative deaths; 14 women died within the six-week postsurgery (a crude mortality rate of 3.8/1000, 2.5-6.4). CONCLUSIONS: Hysterectomy is a common, routine surgery with comparatively rare serious complications. However, younger women, women with more vascular pelvis, who undergo hysterectomy, especially laparoscopically assisted vaginal surgery for symptomatic fibroids, are at most risk of experiencing severe complications both operatively and post-operatively. Therefore, a less invasive alternative treatment for symptomatic fibroids could particularly benefit this group of women, while less invasive treatments for dysfunctional uterine bleeding, such as various methods of endometrial ablations or resections, would need to meet the current low levels of clinical complications in order to replace hysterectomy.

Pre-myomectomy uterine artery embolisation minimises operative blood loss.

Women with massive fibroids (extending beyond the level of the umbilicus) are conventionally offered a hysterectomy, rather than myomectomy, which is considered too technically challenging, with risks of excessive haemorrhage. Some women desire fertility, or may simply wish to preserve their uterus. Uterine artery embolisation is a relatively new treatment for fibroids, and complication rates are thought to be high with massive fibroids. We have performed uterine artery embolisation immediately prior to myomectomy, and found a reduction in blood loss. Uterine artery embolisation may be a useful adjunct to surgery in women with massive fibroids or for whom uterine artery embolisation alone is considered inadequate primary treatment, those with previous myomectomy where surgery might be complicated by extensive adhesions, in Jehovah's Witnesses and in other women who refuse blood transfusion.

Relation of pulmonary lymphangio-leiomyomatosis to use of the oral contraceptive pill and fertility in the UK: a national case control study.

BACKGROUND: Pulmonary lymphangioleiomyomatosis is a rare progressive disease of unknown aetiology affecting premenopausal women. Since the oral contraceptive pill has been implicated in its pathogenesis, a case control study was carried out to determine whether women with the disease were more likely to have taken the oral contraceptive pill, and whether the disease was associated with other conditions related to sex hormones including pregnancy, parity, and fibroids. METHODS: All chest physicians in the UK were asked for details of all live patients with pulmonary lymphangioleiomyomatosis; the patient's family doctor was then asked for four age and sex matched control subjects from their patient register. Details of lifetime use of the oral contraceptive pill, pregnancy, parity, history of fibroids, and smoking were obtained from cases and controls. Relative odds of exposure to potential risk factors were estimated by conditional logistic regression. RESULTS: Medical details were obtained from all 23 cases of lymphangioleiomyomatosis identified; questionnaires were completed by 21 cases (one by proxy) and by 46 matched controls of mean (SD) age 43 (10) and 44 (11) years, respectively. The patients had a mean age of 34 (9) years at onset of symptoms and a median (range) time of 2 (0-29) years from onset of symptoms to diagnosis. Compared with control subjects, cases did not differ in the use of the oral contraceptive pill (odds ratio (OR) 0.39, 95% CI 0.09 to 1.68), diagnosis of fibroids (OR 3.12; 95% CI 0.52 to 18.7), age of menarche, menstrual history, or lifetime smoking. They were, however, less likely to have been pregnant (OR 0.14, 95% CI 0.03 to 0.71) or to have had children (OR 0.13, 95% CI 0.03 to 0.67). More pregnancies had ended in spontaneous abortion (28% v 8%) but the proportion of women undergoing spontaneous abortion was similar in cases and controls (OR 2.13, 95% CI 0.47 to 9.3). CONCLUSIONS: This study does not support the hypothesis that use of the oral contraceptive pill is causally associated with the development of pulmonary lymphangioleiomyomatosis. Sex hormones may be involved, however, since patients were less likely to have been pregnant or to have had children, and tended to have had more spontaneous abortions and an increased incidence of fibroids.

Sonohysterographic findings of endometrial and subendometrial conditions.

Sonohysterography has become the standard test in the evaluation of dysfunctional uterine and postmenopausal bleeding because it allows reliable differentiation between focal and diffuse endometrial and subendometrial lesions, with the most common being polyps and submucosal fibroids. An endometrial polyp usually appears as a well-defined, homogeneous, polypoid lesion that is isoechoic to the endometrium with preservation of the endometrial-myometrial interface. Atypical polyps have cystic components, multiplicity, a broad base, and hypoechogenicity or heterogeneity. Submucosal fibroids are usually broad-based, hypoechoic, well-defined, solid masses with shadowing and an overlying layer of echogenic endometrium that distorts the endometrial-myometrial interface. Atypical fibroids are pedunculated or have a multilobulated surface. The major advantage of sonohysterography is that it can accurately depict the percentage of the fibroid that projects into the endometrial cavity. Endometrial hyperplasia usually appears as diffuse thickening of the echogenic endometrial stripe without focal abnormality, but occasionally focal hyperplasia can be seen. Endometrial cancer is typically a diffuse process, but early cases can appear as a polypoid mass. Adhesions usually appear as mobile, thin, echogenic bands that bridge a normally distensible endometrial cavity, but occasionally thick, broad-based bands or complete obliteration of the endometrial cavity is seen. Although endometrial lesions have characteristic features, a wide range of appearances is possible, with significant overlap between entities. Radiologists should be familiar with the broad spectrum of findings that may be seen at sonohysterography in both benign and malignant processes to raise the appropriate level of concern and to direct the clinician toward the appropriate means of diagnostic biopsy or surgery.

Imaging manifestations of complications associated with uterine artery embolization.

Uterine artery embolization (UAE) is an increasingly performed, minimally invasive alternative to hysterectomy or myomectomy for women with symptomatic uterine fibroids. A growing body of literature documents symptomatic improvement in the majority of women who undergo UAE. Although UAE is usually safe and effective, there are a number of known complications associated with the procedure. Major complications include fibroid passage, infectious disease (endometritis, pelvic inflammatory disease-tubo-ovarian abscess, pyomyoma), deep venous thrombosis, pulmonary embolism, inadvertent embolization of a malignant leiomyosarcoma, ovarian dysfunction, fibroid regrowth, uterine necrosis, and even death. Minor complications include hematoma, urinary tract infection, retention of urine, transient pain, and vessel or nerve injury at the puncture site. As UAE takes its place in the treatment arsenal for women with symptomatic fibroids, radiologists need to be familiar with UAE-associated complications, which may require further treatment and may even be life threatening in some cases. Knowledge of these complications and their imaging features should lead to prompt diagnosis and appropriate treatment.

Efficacy of the levonorgestrel intrauterine system in treating menorrhagia: actualities and ambiguities.

OBJECTIVE: To review the literature on usage of the levonorgestrel intrauterine system (LNG IUS) in women with fibroids or adenomyosis in an attempt to develop a pragmatic approach when faced with enlarged uteri. DATA SOURCES: Computerised searches of MEDLINE and EMBASE up to December 2000. Some of the information was obtained from references listed in the primary sources and references already known to the authors. STUDY SELECTION: Studies and case reports were excluded if they did not specifically provide information about LNG IUS usage in women with fibroids and adenomyosis. DATA EXTRACTION AND SYNTHESIS: After perusal, each relevant publication was summarised and appraised in terms of whether it contained information relevant to the stated objective. DISCUSSION: This area is sparsely researched, as there were no randomised-controlled studies. One large contraceptive study suggests the LNG IUS has a protective effect from the complications of uterine fibroids and smaller case studies suggest it is also useful in women with symptomatic fibroids. However, there is also evidence of an increased risk of expulsion and there may be a place for initial adjunctive medical treatment to minimise this risk. An observational study and isolated reports of women with adenomyosis report significant symptomatic relief in these women. CONCLUSION: Available data refute the notion that uterine enlargement is a contraindication to insertion of the LNG IUS, but there appear to be reasons for a cautious approach when dealing with pathological uteri.

Uterine artery embolization for the treatment of adenomyosis: clinical response and evaluation with MR imaging.

OBJECTIVE: This study was performed to evaluate the MR imaging appearance and clinical response of patients undergoing uterine artery embolization for the treatment of menorrhagia due to adenomyosis. MATERIALS AND METHODS: A retrospective review of 15 patients with adenomyosis and menorrhagia who underwent uterine artery embolization was performed. The diagnosis of adenomyosis was based on established MR imaging criteria. Clinical response was assessed at a minimum of 3 months after embolization. Follow-up MR imaging was performed 6 months after embolization. RESULTS: Of the 15 patients in this study, five had diffuse adenomyosis without evidence of uterine fibroids, one had focal adenomyosis without evidence of uterine fibroids, and the remaining nine had adenomyosis with one or more fibroids. At follow-up, 12 (92.3%) of the 13 patients reported significant improvement in presenting symptoms and quality of life. One patient continued experiencing menorrhagia, and one patient experienced amenorrhea during the 5 months of follow-up after embolization. MR imaging in nine patients, performed at a mean of 5.9 months after embolization, revealed significant reductions in median uterine volume (42%), median fibroid volume (71%), and mean-junctional-zone thickness (11 mm; 33%; p < 0.5). Six of the nine patients had subendometrial regions of decreased T2 signal intensity after embolization. CONCLUSION: Uterine artery embolization is a promising nonsurgical alternative for patients with menorrhagia and adenomyosis. Significant improvement in presenting symptoms and in quality of life is associated with decreases in uterine size and junctional zone thickness. Larger prospective studies are needed to establish the safety and efficacy of this procedure for patients with adenomyosis.

Uterine artery flow velocity waveforms and color flow imaging in women with perimenopausal and postmenopausal bleeding. Correlation to endometrial histopathology.

We performed Doppler studies of the uterine artery in 85 women with postmenopausal and perimenopausal bleeding. Sixty-six women had non-malignant changes and 19 women had malignant changes on histologic examination of the endometrium. Uterine fibroids were detected in 30 women. When malignant changes were detected in the endometrium, uterine artery resistance index was always below 0.83. The mean uterine artery resistance index was significantly lower in the group of women with pathologic changes of the endometrium (RI = 0.77 +/- 0.03) compared to the group with non pathologic changes (RI = 0.85 +/- 0.08 p < 0.01), excluding the women with uterine fibroids. The lowest mean resistance index in the uterine artery was observed in the group of women with uterine fibroids (RI = 0.60 +/- 0.09 p < 0.001). In five of six patients with endometrial carcinoma blood vessels were detected around the myometrium by using color flow imaging. Their RI was always less than 0.5. In five patients, blood vessels were detected in uterine fibroids but their RI was always more than 0.5. All six women with endometrial carcinoma but only seven of 13 women with endometrial hyperplasia, had endometrial thickness greater than 5 mm. Doppler velocimetry of the uterine artery carries a high sensitivity (100%) in detecting pathological changes of the endometrium in patients presenting with postmenopausal or perimenopausal bleeding. The presence of high resistance in this vessel, may allow a more conservative approach in this group of patients.

Estrogen and progesterone receptor content of enucleated uterine myomata after luteinizing hormone-releasing hormone. Analogue depot therapy.

We wanted to correlate the degree of myoma shrinkage after luteinizing hormone-releasing hormone (LHRH)-analogue depot therapy to the estrogen and progesterone receptor content of the enucleated fibroids. Twenty premenopausal, regularly menstruating women wishing to preserve their childbearing capacity were treated for three to six months with 3.75 mg of leuprorelin acetate depot subcutaneously. Four weeks after the last injection, all fibroids were enucleated and investigated immunohistochemically by using monoclonal (rat) antibodies to human estrogen and progesterone receptors. The localization and distribution of nuclear staining was visualized through a light microscope and scored semiquantitatively by multiplying the staining intensity with the percentage of positive cells. Although LHRH-analogue depot therapy led to almost the same degree of ovarian suppression in all of the women, extent of myoma shrinkage varied from 0% to 87%. On the other hand the extent of myoma regression correlated significantly to the estrogen receptor content of the enucleated fibroid, while diminution of myoma size seemed to be independent of the progesterone receptor. This indicates an association between myoma shrinkage and the estrogen receptor status of the enucleated fibroid. It remains to be proved that pretreatment receptor analysis may predict the myomata that are sensitive to endocrine treatment.

Uterine artery embolization: sonographic imaging findings.

OBJECTIVE: To examine the sonographic and angiographic imaging findings before and after uterine fibroid embolization for symptomatic leiomyoma. METHODS: This prospective study involved 14 premenopausal women who underwent uterine fibroid embolization for symptomatic leiomyoma. Preprocedure sonography with color Doppler imaging was performed. Bilateral uterine artery embolization was successfully performed with the use of polyvinyl alcohol. Follow-up sonographic examinations were performed between 1 and 3 months after the procedure. The correlation between the sonographic appearance before and after embolization and the degree of decrease in uterine size was evaluated by using the Jonckheere-Terpstra 2-sided P test. RESULTS: Preprocedure sonographic imaging showed a varied appearance to the fibroids. Color Doppler imaging primarily showed the fibroids to be vascular with marked peripheral blood flow. Postprocedure sonographic imaging showed decreased uterine size and echogenicity. Color Doppler imaging showed a marked decrease in the blood flow to the leiomyoma. There was no statistical significance in the relationship between echogenicity and vascularity shown before the procedure and the percent decrease in the size of the uterus. CONCLUSIONS: Although sonography is an efficient method for identifying leiomyomata and determining the reduction in size after uterine artery embolization, we were unable to identify any predictive characteristics of success for aiding the preprocedural assessment.

[The effects of menopausal replacement therapy in women with uterine myomas].

BACKGROUND: The aim of this study was to compare the effects of two different therapies in menopausal women with uterine fibroids. METHODS: Thirty menopausal women with uterine fibroids were evaluated. They were randomized into two groups: the patients included in Group A were treated with transdermal hormonal therapy with 50 micrograms of ethynilestradiol and 5 mg of MAP; the patients in Group B with 2.5 mg of tibolone. The patients of both the groups have been treated for one year. Plasmatic levels of E2, FSH and LH were evaluated before and after treatment and the volume of fibroids was compared by transvaginal ultrasonography at the beginning of the study, after 6 months and after 1 year. RESULTS AND CONCLUSIONS: The results suggest that transdermal hormonal therapy increases significantly the volume of the fibroids while tibolone does not.
