Distal inferior mesenteric veins to renal vein shunt for treatment of bleeding anorectal varices: case report and review of literature.

Isolated intractable bleeding from anorectal varices is a rare complication of portal hypertension. We report a case of a patient with cirrhosis and hepatofugal flow who had severe lower gastrointestinal bleeding from anorectal varices. This is the first case report of construction of a distal inferior mesenteric vein shunt to left renal vein as a selective shunt for treatment of bleeding anorectal varices in a patient with hepatofugal flow. The patient is a 39-year-old white man with a medical history significant for alcohol abuse who was seen with bright red blood per rectum requiring 10 units of packed red blood cells over the course of a year. The work-up revealed anorectal varices with no other colonic lesions. The patient underwent construction of a distal inferior mesenteric vein to left renal vein shunt.

[Clinical anatomy of collateral varicose veins (essential varicose veins of the legs)].

Performance of ambulatory phlebectomies has greatly enhanced the anatomo-clinical description of collateral varicosities (CV), permitting a better understanding of their physio-pathological role, and acknowledging, in some instances, their true autonomy. Physio-pathological role:--Reflux transfer--The function of CV is not limited to a mere acknowledgment (vector function) of the refluxes from the long pathological axes on which they branch. This function also consists in ensuring the diversion (transfer function) from one territory to another.--Pathology transfer--This reflux transfer is sometimes accompanied with a pathology transfer in the new territory (pathology steals). Anatomo-clinical description:--Supra-limb collaterals--These are CV with a parieto-abdominal course and pelvic CV, developed below the origin of the limb.--Proximity collaterals--These are "ladder-shaped" collaterals with oblique bars!, uniting adjacent long axes.--Inter-axial collaterals--These are crural, tibial of cruro-tibial CV, uniting distant long axes and providing junctions between medial and lateral saphenous veins, lateral and medial saphenous veins, saphenous veins-peroneal axis... Situations of autonomy: Independence regarding long axes, is demonstrated by the autonomous nature of the original reflux and affects, more especially: the antero-lateral crural slings, the lateral pudental vessels, the popliteal veins. The treatment of collateral varicosities involves surgery, ambulatory phlebectomy, sclerosis with could be implemented separately or concomitantly.

[Color-coded duplex sonography in diagnosis of primary varicose veins and recurrent varicose veins].

Varicose vein surgery, adapted to obtaining condition, requires highly accurate preoperative diagnostics as a basic requirement. The Colour Doppler ultrasound allows one to ascertain the morphological, topographical and functional condition of the venous system and thereby makes possible an operation appropriate for the stage. Thirty-six patients who preoperatively were subject to this examination could be clearly classified according to the localisation of the points of insufficiency; also existing insufficient perforans veins were identified. Eleven patients suffering from relapse varicose veins were examined. In the course of examination we identified crosse and parva relapses as well as perforans insufficiencies and subsequently removed them surgically. Our results definitely show that clinical use of colour Doppler ultrasound in the field of preoperative varicose vein diagnostics has considerable advantages compares with the hitherto existing methods and therefore should be applied more extensively.

Argon laser photocoagulation for macular edema in branch vein occlusion. The Branch Vein Occlusion Study Group.

The Branch Vein Occlusion Study is a multi-center, randomized, controlled clinical trial designed to answer several questions regarding the management of complications of branch vein occlusion. This report discusses the question, "Is argon laser photocoagulation useful in improving visual acuity in eyes with branch vein occlusion and macular edema reducing vision to 20/40 or worse?" One hundred thirty-nine eligible eyes were assigned randomly to either a treated or an untreated control group. Comparing treated patients to control patients (mean follow-up 3.1 years for all study eyes), the gain of at least two lines of visual acuity from baseline maintained for two consecutive visits was significantly greater in treated eyes (P = .00049, logrank test). Because of this improvement in visual acuity with argon laser photocoagulation of macular edema from branch vein occlusion, we recommend laser photocoagulation for patients with macular edema associated with branch vein occlusion who meet the eligibility criteria of this study.

An anatomical study of the human cardiac veins with special reference to the drainage of the great cardiac vein.

Many case reports in which the main aim was to clarify the development of the superior vena cava (SVC) with persistent SVC have so far been published. However, there have only been a few systematic studies of the cardiac veins. Therefore, we macroscopically investigated the cardiac veins using 337 human adult hearts to obtain a detailed understanding of the morphology of the heart. From our study, we obtained the following results. 1. The frequency of persistent left SVC including one case of bilateral SVC was observed to be higher 7 cases (2.1%) than in previous reports. 2. We observed a second case in which the great cardiac vein drained directly into the right SVC (the first case being reported by Bergman et al. 1988). 3. Variations in the drainage of the great cardiac vein (GV) were observed from the right SVC to the left SVC, while the middle cardiac vein (MV) showed less variations of the drainage and course. 4. The drainage boundary between the GV and MV was classified into 3 types: MV-dominant type in 123 cases (36.5%), intermediate type in 182 cases (54.0%), and GV-dominant type in 32 cases (9.5%). From our results, we speculated that the MV did not generate any variations due to its short course before draining into the right atrium, while the GV had many variations due to its long course before draining into the right atrium. From the few GV-dominant types, the halfway boundary between the anterior (GV) and posterior (MV) route for drainage into the right atrium could be considered to be the anterior side rather than the Apex cordis.

Comparison of 3 and 6 months of oral anticoagulant therapy after a first episode of proximal deep vein thrombosis or pulmonary embolism and comparison of 6 and 12 weeks of therapy after isolated calf deep vein thrombosis. Pinede L, Ninet J, Duhaut P et al for the Investigators of the 'Durée Optimale du Traitement Antivitamines K' (DOTAVK) study. Circulation 2001; 103: 2453-60.

QUESTION: Is anticoagulant treatment for calf vein thrombosis for 6 weeks duration associated with acceptable recurrence and safety outcomes? Is anticoagulant therapy for 3 months duration for proximal deep vein thrombosis (DVT) or pulmonary embolism (PE) associated with acceptable recurrence and safety outcomes? POPULATION: Men and women with a first episode of symptomatic calf vein thrombosis or proximal DVT confirmed by ultrasound or venography, or PE confirmed by lung scan or angiography. Patients with pregnancy, thrombophilia, severe PE, and cancer were excluded. DESIGN AND METHODS: After treatment with heparin and oral anticoagulants targeting an INR of 2-3, patients with calf DVT were randomized to 6 weeks (n = 105) versus 3 months (n = 92) of treatment, and patients with proximal DVT and/or PE were randomized to 3 months (n = 270) versus 6 months (n = 269) of treatment. The outcome events were recurrences and major, minor, or fatal bleeding complications. The mean follow-up time was 12 months. RESULTS: A total of 736 patients were enrolled. For calf vein thrombosis the recurrence of DVT or PE after 6 weeks of therapy was 2/105 (2.0%) versus 3/92 (3.4%) with 3 months of therapy, relative risk of 0.58 (95% CI: 0.10-3.36). The rates of major bleeding were 1/105 (1.0%) and 3/92 (3.4%) respectively, relative risk of 0.29 (95% CI: 0.03-2.72). For proximal DVT or PE, the recurrence rate after 3 months of therapy was 21/270 (8.1%) versus 23/269 (8.7%) after 6 months of treatment, relative risk of 0.93 (95% CI: 0.53-1.65). The rates of major bleeding were 5/270 (1.9%) versus 7/269 (2.6%) respectively, relative risk of 0.73 (95% CI: 0.24-2.27). CONCLUSION: After isolated calf vein DVT, 6 weeks of oral anticoagulation is sufficient. For proximal DVT or PE, 3 and 6 months of anticoagulant therapy is equivalent. For patients with temporary risk factors who have a low risk of recurrence, 3 months of treatment seems to be sufficient.

Occlusion of the subclavian vein associated with cephalic vein pacemaker electrodes.

Thrombosis and occlusion of major veins have been described following the use of transvenous pacing electrodes for the establishment of permanent cardiac pacing. The frequency of such complications is, however, not well known. A series of 125 patients was therefore reviewed, all of whom had been paced with permanent transvenous electrodes through a cephalic vein. There was clinical and venographic evidence of subclavian vein occlusion in only 3 of these patients. A further 20 of these patients were also subjected to venography and showed no radiographic evidence of venous occlusion although minor thrombosis associated with the pacemaker electrode was found in one patient. It is concluded that the convenience of using the cephalic vein as a route for the insertion of transvenous pacing electrodes outweighs the small risk of major venous occlusion.

Axillary vein approach for pulmonic valvuloplasty in infants with iliac vein obstruction.

Repeated pulmonic balloon valvuloplasty from the axillary vein was performed in two infants with initial transvalvular gradients of 131 and 162 mm Hg. The first angioplasty was performed through the femoral vein and improved the valve gradient in both patients. Because of obstruction of the iliac system the axillary vein approach was used for the second angioplasty. The transaxillary pulmonic valvuloplasty decreased the gradient to acceptable levels, and no complications were noticed. The axillary vein approach can be the alternative to the femoral one in cases with obstructed iliac system or interrupted inferior vena cava.

A comparative study of saphenous vein, internal jugular vein, and knitted Dacron patches for carotid artery endarterectomy.

To determine whether the choice of material used for patch closure following carotid artery endarterectomy (CAE) affected the immediate operative results, the early follow-up results, or the incidence of early restenosis, a retrospective study of 275 consecutive carotid endarterectomies by two vascular surgeons was performed. Among 275 primary CAEs performed between July 1991 and August 1993, 159 (57.8%) were closed with saphenous vein (SV), 25 (9.1%) with double-thickness internal jugular vein (JV), and 91 (33.1%) with knitted Dacron (KD). Primary closure was not used in any of the arteries in this series. The overall perioperative mortality rate was 1.1% and the rate of major and minor morbidity was 4.4% There were four (1.5%) perioperative strokes: two (1.3%) in the SV group, one (4.0%) in the JV group, and one (1.1%) in the KD group. Two-hundred fifty-eight (93.8%) of the 275 endarterectomies were followed postoperatively for 2 to 35 months (mean 14.4). Two-hundred nineteen (79.6%) were evaluated using duplex scans during follow-up with a mean interval of 13.7 months. Of the arteries studied, four (3.6%) in the SV group, none in the JV group, and six (8.4%) in the KD group demonstrated restenosis of > 50% at the time of follow-up (NS). In addition, one (0.9%) artery in the SV group, one (5.6%) in the JV group, and none in the KD group demonstrated complete occlusion. Retrospective analysis of the data showed no statistically significant differences in perioperative morbidity, mortality, or early postoperative restenosis whether the artery was closed with saphenous vein, jugular vein, or knitted Dacron patches. Longer follow-up is needed to determine whether rates of late restenosis and aneurysmal dilation will differ between synthetic and autologous patches.

Umbilical and portal vein calcification following umbilical vein catheterization.

Calcifications of the umbilical vein and intrahepatic branches of the portal vein developed in a newborn who had an umbilical vein catheter inserted for 11 days postnatally. The calcified intrahepatic portal veins can still be demonstrated sonographically at the age of three years, but these calcifications were no longer detectable radiologically.

Femoral vein pressure measurements for evaluation of venous function in patients with postthrombotic iliac veins.

Fifty patients with postthrombotic disease were examined by phlebography and by bilateral femoral vein pressure measurements. The degree of obstruction to venous flow was best evaluated by measuring the pressure elevation and pressure difference after exercise and the time required for these parameters to return to pre-exercise levels; pressures during rest and exercise were less conclusive indicators of obstruction. Good correspondence was found between femoral vein pressure and the severity of postthrombotic symptoms, while phleboraphy provided largely morphologic, rather than functional, information. We, therefore, consider it important to determine femoral vein pressure during and after exercise to evaluate the significance of postthrombotic iliac vein disease.

Stripping operation with sclerotherapy for primary varicose veins due to greater saphenous vein reflux: three-year results.

The purpose of this study was to compare the recurrence-free rates of stripping with varicectomy and stripping with sclerotherapy for the treatment of primary varicose veins due to greater saphenous vein insufficiency. This is a multicenter retrospective analysis of 186 patients and 220 limbs treated for primary varicose veins due to greater saphenous vein reflux from January 1996 to December 1997. The difference between the two groups was evaluated by the Chi(2) test or t-test. The recurrence-free rates were estimated by the Kaplan-Meier life-table method. The mean follow-up period was 3.2 +/- 1.1 years. The clinical backgrounds of patients with varicectomy stripping and sclerotherapy stripping were not significantly different between the two groups. The overall recurrence-free rates at 1 and 3 years were 97.0% and 91.4%, respectively. The recurrence-free rates at 3 years were 93.5% for stripping with varicectomy and 88.6% for stripping with sclerotherapy. No statistical difference was found between the two groups. The recurrence rate after stripping with sclerotherapy was equivalent to that after stripping with varicectomy. Thus concurrent varicectomy can be replaced with sclerotherapy.

Retroaortic left renal vein joining the left common iliac vein.

Retroaortic left renal vein joining the left common iliac vein is a rare congenital anomaly in the development of the inferior vena cava. To our knowledge, only one case has been reported in the literature; however, its imaging features have never been described. A 27-year-old male presented with a 1-year history of recurrent right flank pain, dysuria, hematuria, and fever (39 degrees C). Computed tomography and MR venography showed a retroaortic left renal vein joining the left common iliac vein. We present the CT and MR venography findings and discuss their feasibility in showing this congenital anomaly.

Great saphenous vein stripping with liberal use of subfascial endoscopic perforator vein surgery (SEPS).

This study is based on a unique registry of 632 patients who underwent great saphenous vein (GSV) stripping and liberal use of subfascial endoscopic perforator vein surgery (SEPS) for minimal to severe lower limb venous insufficiency. Clinical examinations and color-coded duplex scanning were performed on a randomly selected, manageable sample of 170 limbs to assess the affect of early SEPS on junctional (saphenofemoral [SFJ] and/or saphenopopliteal [SPJ]) and perforator vein (PV) insufficiencies and superficial varicosities at a median of 6.5 years. PV incompetence was present in 68 legs (40%), as the sole transfascial insufficiency in 28 limbs and combined with SFJ or SPJ incompetence in 40 limbs. Junction incompetence alone characterized an additional 38 limbs, bringing the total transfascial insufficiency prevalence to 62%. Superficial varicosities affected 46% of limbs. Overall CEAP clinical class was unimproved beyond preoperative values. PV incompetence was associated with higher CEAP and clinical venous severity scores than were junctional insufficiencies alone. We concluded that PV incompetence alone or combined with junctional insufficiency is associated with increased symptoms and disease progression. The prevalence of SFJ, SPJ, and PV incompetence (62%) and recurrent varicosities (46%) suggests that early use of SEPS does not prevent disease progression and offers no benefit over GSV stripping in the absence of deep vein insufficiency or threatened ulceration.

Change of serum HPL level in maternal vein, umbilical cord vein and artery in mature and premature labour.

The authors examined the possible role of HPL in the onset of labour. The HPL level of the maternal vein, the umbilical cord vein and artery was compared in vaginal mature (n = 16) and premature (n = 52) deliveries. The HPL concentration was also examined in mature (n = 18) and premature (n = 18) deliveries performed by caesarean section prior to the onset of labour. The results showed that: the serum HPL level in the maternal vein, the umbilical cord vein and artery was lower during the 33rd-36th and the 40th weeks in cases of vaginal delivery compared to elective caesarean section; The artery/vein ratio decreases during labour (A/V X 100 value), indicating that HPL metabolism in the fetus decreases during regular labour pains; The onset of premature labour and delivery was associated with lower HPL levels compared to normal pregnancy. The authors assume that the lower HPL level found in cases of vaginal delivery may be due to reduced placental perfusion, but they do not exclude the possible association of lower HPL concentrations in cases of premature delivery.

Right inferior phrenic vein indicating the right hepatic vein confluence into the inferior vena cava.

BACKGROUND: Limiting backflow bleeding from the hepatic veins is a priority when performing hepatectomy. However, hepatic vein encirclement is difficult, especially in re-resection. We verified the presence and trajectory of the right inferior phrenic vein (RIPV), which could be a useful anatomic landmark to guide surgeons in targeting the extrahepatic right hepatic vein (RHV) before dissection. METHODS: Between May 2001 and January 2005, 100 consecutive patients with liver tumors were enrolled and underwent hepatectomy: 77 patients underwent surgery for tumors located in the right hemiliver. RESULTS: RIPV was detected in all but 1 patient (99%), and its trajectory was always guided toward the extrahepatic RHV. The only patient in whom RIPV was not detected had undergone prior liver resection and interstitial therapies for colorectal cancer liver metastases. CONCLUSIONS: Apart from exceptional conditions, detection of the RIPV is always feasible and allows safe surgical dissection while approaching the extrahepatic RHV before hepatic resection.

Reconstruction of the middle hepatic vein tributaries using the recipient's recanalized umbilical vein in right-lobe living-donor liver transplantation.

BACKGROUND: Right-lobe grafts without the middle hepatic vein (MHV) can cause severe congestion of the anterior segment in living-donor liver transplantation (LDLT). However, the indications and methods for reconstructing the MHV or its tributaries remain controversial. METHODS: We herein describe two cases of the successful use of the recipient's recanalized umbilical vein as an interposition graft to drain the major MHV tributaries in right-lobe LDLTs. RESULTS: After surgery, both right-lobe grafts are currently functioning well and all of the reconstructed venous tributaries have been confirmed to be patent by doppler ultrasonography. The histopathological features of the recanalized umbilical vein showed an intact intima with thickened media. CONCLUSIONS: The use of the recipient's recanalized umbilical vein is a good option for reconstructing MHV tributaries in right-lobe LDLTs.

Surgical technique for inferior mesenteric vein to renal vein shunt in portal hypertension.

An important role still exists for the creation of surgical portasystemic shunts. Multiple techniques have been described. However, no particular one is satisfactory for all clinical situations. The objective of the present paper is to describe an alternative surgical technique for the creation of a decompressive portasystemic shunt. This technique consists of an end-to-side anastomosis between the inferior mesenteric vein and the left renal vein. In our experience, the inferior mesenteric vein to left renal vein anastomosis may be a useful portal decompressive shunt for patients with otherwise difficult peri-portal or peri-pancreatic anatomic exposures. This technique should be a useful tool in the armamentarium of surgeons dealing with patients who need portal decompressive surgical shunts.
