The B-Lynch surgical technique for the control of massive postpartum haemorrhage: an alternative to hysterectomy? Five cases reported.

The B-Lynch suturing technique (brace suture) may be particularly useful because of its simplicity of application, life saving potential, relative safety, and its capacity for preserving the uterus and thus fertility. Satisfactory haemostasis can be assessed immediately after application. If it fails, which has not yet been the case, other more radical surgical methods as mentioned in this paper and in the literature can be considered. The special advantage of this innovative technique is an alternative to major surgical procedures to control pelvic arterial pulse pressure or hysterectomy. This suturing technique has been successfully applied with no problems to date and no apparent complications.

Influence of hypertensive disorders and cigarette smoking on placental abruption and uterine bleeding during pregnancy.

OBJECTIVE: To assess the influence of hypertensive disorders in pregnancy on the subsequent risk of placental abruption and uterine bleeding of unknown aetiology, and to examine the combined effects of hypertensive disorders and cigarette smoking during pregnancy on the risk of uteroplacental bleeding disorders. DESIGN: Retrospective cohort study. SETTING: Data for this study were derived from the Nova Scotia Atlee Perinatal database, Canada, comprising of women who were delivered in the province between 1980 and 1993. POPULATION: 120,666 pregnancies resulting in singleton births, of which 13,360 pregnancies were complicated by pre-eclampsia and/or chronic hypertension. MAIN OUTCOME MEASURES: Risks and relative risks of placental abruption and uterine bleeding of unknown aetiology in pregnancies complicated by chronic hypertension, mild and severe pre-eclampsia, and chronic hypertension with superimposed pre-eclampsia, each compared with normotensive patients. Adjusted relative risks were obtained through the fit of multivariable logistic regression models based on the method of generalised estimating equations. RESULTS: Chronically hypertensive women had no increased risk of abruption (RR 1.4; 95% CI 0.5-3.6), while women whose pregnancies were complicated by severe pre-eclampsia (RR 3.8; 95% CI 2.1-6.9), and chronic hypertension with superimposed pre-eclampsia (RR 2.8; 95% CI 1.2-6.3) showed strong associations with placental abruption. However, none of the hypertensive disorders were associated with uterine bleeding of unknown aetiology. The association between placental abruption and hypertensive disorders varied by parity. Parous women with chronic hypertension and superimposed pre-eclampsia were at greater risk of placental abruption (aRR 3.8; 95% CI 1.9-7.8) than nulliparous women with chronic hypertension and superimposed pre-eclampsia (aRR 1.6; 95% CI 0.5-4.9). The joint effects of smoking and hypertension had a greater effect on the risk of placental abruption than would have been expected based on their individual effects. CONCLUSIONS: The pattern of association between placental abruption and hypertension varied in relation to the specific type of hypertensive disorder. However, uterine bleeding of unknown aetiology was not associated with hypertension. Findings from this study suggest that placental abruption and uterine bleeding of unknown origin are aetiologically distinct obstetric complications with respect to hypertensive disorders during pregnancy.

Polymorphisms in various coagulation genes in black South African women with placental abruption.

This pilot study examined Factor V Leiden (R506Q), prothrombin (20210G-->A), thrombomodulin (A455V) and MTHFR (677C-->T) in 100 Zulu-speaking black South African women with placental abruption and 217 controls. The Factor V Leiden and prothrombin variant gene alleles were not detected in either patient or control groups. The thrombomodulin polymorphic variant was not seen in the patient group but three heterozygotes (1%) were found in the controls. No homozygotes for the MTHFR T677 variant were detected in the patients but two (1%) were noted in the controls; the normal and heterozygote genotype and allele frequencies for this polymorphism were similar in the two groups.

Pregnancy following uterine artery embolisation for symptomatic fibroids: a series of 26 completed pregnancies.

OBJECTIVES: To evaluate the outcome of pregnancies after uterine artery embolisation for uterine fibroids. DESIGN: Retrospective analysis of pregnancy subsequent to uterine artery embolisation by one interventional radiologist. SETTING: A UK District General Hospital. POPULATION: Twenty-nine pregnancies in 671 women who had undergone uterine artery embolisation. METHODS: Cases were identified by screening questionnaire and from the study database. Detailed information was collected by questionnaires, direct conversations with women and, when necessary, from hospital records. MAIN OUTCOME MEASURES: Pregnancy outcome, complications and neonatal outcomes. RESULTS: Of 26 completed pregnancies, detailed information was available for 24 and limited information for 2. Seven (27%) ended in miscarriage, there were two terminations and one ectopic pregnancy. Of 16 deliveries after 24 weeks, first and second trimester bleeding occurred in 40% and 33%, respectively, 4 (25%) had preterm deliveries and the caesarean section rate was 88%. Two (13%) women developed proteinuric hypertension and two others had preterm spontaneous rupture of the membranes. Fourteen of 16 cases were delivered by caesarean section. The rate of primary postpartum haemorrhage was 3/15 (20%). The mean birthweight of term babies was 3.39 kg (SD 0.64) and none required admission to neonatal intensive care. There was one (6.7%) case of fetal growth restriction. CONCLUSION: Although this study is relatively small, there is an increase in delivery by caesarean section. There does not appear to be any other major excess obstetric associated risk when the demographics of the population in question is considered.

Maternal total vascular resistance and concentric geometry: a key to identify uncomplicated gestational hypertension.

OBJECTIVE: To evaluate the prognostic impact of elevated total vascular resistance (TVR) on the outcome of pregnancy in early mild gestational hypertension (EMGH). DESIGN: Prospective observational study. SETTING: Data collected from women with EMGH referred to the obstetrics outpatient clinic of Tor Vergata University from June 2003 to June 2005. POPULATION: A total of 268 women with EMGH (systolic and diastolic blood pressure [BP] 140-150 mmHg and 90-99 mmHg, respectively, without significant proteinuria). METHODS: Women had a maternal echocardiographic examination and BP examination within 24 hours of diagnosis. From this, the TVR was calculated and the geometric pattern of the left ventricle assessed. MAIN OUTCOME MEASURES: Fetal/maternal adverse outcomes (pre-eclampsia, preterm delivery, placental abruption, other maternal medical problems, fetal distress, neonatal low birthweight, admittance to neonatal intensive care unit and perinatal death). RESULTS: Ninety-two out of the 268 pregnancies showed adverse outcomes (34.3%). The best independent predictor for the composite of maternal and fetal complications was TVR (OR 64.4, 95% CI 25.9-160.1). The cutoff value was 1340 dyn seconds/cm(5) with a sensitivity and a specificity of 90 and 91%, respectively. Concentric geometry of the left ventricle was also an independent predictor (OR 4.72, 95% CI 1.85-12.04). CONCLUSIONS: Echocardiography could help in identifying women with EMGH who subsequently develop maternal and fetal complications, allowing a classification in high-risk (TVR > 1340 dyn seconds/cm(5), concentric geometry of the left ventricle) and low-risk women (TVR < 1340 dyn seconds/cm(5), nonconcentric geometry of the left ventricle) for adverse outcomes of pregnancy.

The use of daily fetal movement records in a clinical setting.

A variety of biochemical and biophysical techniques are used for the assessment of fetal well-being in high-risk pregnancy. Based on clinical experience, the daily fetal movement record has been found to be an inexpensive, non-invasive, simple tool that may be used for the continuous assessment of the fetus by the mother. The daily fetal movement record may predict fetal distress occurring in the interim between other assessments. Patients are instructed to count the number of fetal movements perceived in a 30-minute period, three times per day. The daily fetal movement record is a screening tool that may signal the need for further fetal well-being assessment. The tool promotes the mother's active participation in assessment of her high-risk fetus and may encourage maternal-fetal attachment.

Motor vehicle accident during the second or third trimester of pregnancy.

OBJECTIVE: To evaluate the need of immediate treatment, follow-up and consequences of different types of traffic accidents during pregnancy. METHOD AND MATERIAL: A retrospective analysis covering five years involving thirty-five pregnant women involved in motor vehicle accidents at 22-39 weeks of gestation. RESULTS: Fifteen of the 35 women were involved in frontal impact collisions, and suffered mild subjective and objective symptoms; all their fetuses survived and were delivered at term. Fifteen other women were involved in broadside collisions; two of these were riding a bicycle. These 15 women had clear objective findings like uterine contractions or tenderness, and some of them needed tocolytic therapy and hospitalization up to eight days. This was significantly longer than in those involved in frontal impact collisions. However, the broadside accidents did not have any adverse effect on pregnancy outcomes either. Five women were involved in serious accidents at speeds of 80-110 km/h, and one mother and her fetus died immediately because of rupture of the uterus and the cervical joint and spinal canal. Four other fetuses were found dead on arrival at hospital or soon after. In all cases the cause of fetal loss was placental abruption. The presence of fetal blood cells in maternal blood was evaluated in 15 of 35 patients, but was positive in only one. CONCLUSION: Frontal collisions are associated with lower vehicular speed, less trauma and no acute or later effects on pregnancy, whereas broadside collisions and high speed (> 80 km/h) cause more symptoms. The latter type of accidents are associated with high risk of placental abruption and of fetal and maternal death. Fortunately the symptoms are evident immediately after the accident, and early hospital discharge is possible if no abnormalities are present during the first hours.
