Extrahepatic portal-vein obstruction in pregnancy

BackgroundExtrahepatic portal-vein obstruction (EHPVO) is a common cause of portal hypertension in developing countries. The main risk in pregnant women with this condition is variceal bleeding, which may be life-threatening. The objective of our study was to assess the outcome of pregnancy in women with EHPVO.Materials and MethodsA retrospective analysis of 21 pregnancies in 12 women with EHPVO was carried out at a tertiary hospital in India.ResultsThe mean age of pregnant women with EHPVO was 25.3 years, and the mean duration of disease since diagnosis was 6.1 ± 1.2 years. All the patients had chronic EHPVO, and two patients were diagnosed in the index pregnancy. The incidence of abortion, preterm deliveries, and small for gestational age fetus was 23.8%, 18.7%, and 12.5%, respectively. Thrombocytopenia was found to complicate 61.9% of the pregnancies, while anemia was detected in 40% of the pregnancies. Variceal bleeding occurred in one woman, who was diagnosed during pregnancy and was managed successfully with endoscopic sclerotherapy. None of the patients who were diagnosed prenatally had variceal bleeding during pregnancy. The outcome in nine pregnancies, in which prenatal endoscopic variceal ligation was done, was compared with eight pregnancies, in which endoscopic sclerotherapy was done. No significant difference between the two groups in terms of pregnancy outcome and complications was found. There were no stillbirths or maternal mortality.ConclusionWomen with EHPVO who have been diagnosed and treated prenatally have a good pregnancy outcome. They should be managed in a tertiary care center with a multidisciplinary approach.
