Embolization of the ovarian veins as a treatment for patients with chronic pelvic pain caused by pelvic venous incompetence (pelvic congestion syndrome).

Ovarian and pelvic (internal iliac) varices have long been recognized as a source of chronic pelvic pain in women. The technique of transcatheter embolotherapy for ovarian and pelvic varices requires selective catheterization of the ovarian and internal iliac veins, followed by contrast venography and embolization. The long-term effects of treatment are the subject of ongoing investigation. This article provides a concise background on ovarian and pelvic varices and reviews the recently published literature on their embolization for the treatment of pelvic venous incompetence (also known as pelvic congestion syndrome).     

Interposition mesocaval shunt for chronic primary occlusion of the hepatic veins.

Five patients with primitive chronic Budd-Chiari syndrome were treated by Dacron interposed mesocaval shunts for medically uncontrollable ascites. In two instances, hepatomegaly and ascites disappeared for four and four and one-half years. In one patient with severe stenosis of the inferior vena cava, moderate ascites required tapping once a month one year later, despite proved prosthesis patency. In two patients, death occurred ten and 30 days after shunting due to thrombosis of the graft. Inferior vena cava stenosis appears to be the major factor for decision of opportunity and type of portacaval shunt. From our material, we can describe three types of stenosis: type I, due to caudate lobe hypertrophy, and type II, due to right lobe hypertrophy, are suitable for side-by-side portacaval or mesocaval shunts. Type III, regular and extended narrowing of inferior vena cava, observed in long term evolutive forms, is presumably due to fibrosis and is not a good indication for conventional infrahepatic shunting procedures. Since this study was completed, another patient had a side-to-side portacaval anastomosis for chronic Budd-Chiari syndrome without caval stenosis. The patient has been observed for seven months, and ascites did not reappear. This underlines the importance of a complete radiologic and hemodynamic preoperative study of inferior vena cava outflow impairment.     

Clinical significance of the doppler evaluation in ductus venosus, hepatic veins and pulmonary veins

Doppler evaluation of the fetal venous system at present improves assessment of fetal well-being in many conditions. Actually, analysis of ductus venosus waveforms seems to be the most important. It place role in detection of genetic abnormalities (in low pregnancies), prediction of outcomes growth-restricted fetuses, assessment of severity of heart failure due to congestive heart anomalies, fetal infections, hydrops fetalis. Hepatic veins are known rather as an additional parameter (for ductus venosus) in the severely compromised fetus. Doppler evaluation of pulmonary veins may be useful in prediction of fetal lung maturity and in detection some difficult circulatory anomalies.
