Abstract

Extrahepatic portal vein obstruction (EPVO) is a common cause of portal hypertension in children and can lead to life-threatening bleeding, thrombocytopenia, and coagulation disorders. Mesoportal bypass (MPB) restores normal physiologic portal flow to the liver and corrects portal hypertension. There is, however, little long-term outcome data after MPB. The aim of our study was to analyze the long-term outcome after MPB in children. Retrospective single-center review of all MPB with more than 5-year follow-up was performed in children between 1998 and 2003. Thirty children underwent MPB, which was successful in 29. Long-term follow-up is available for 24. Median age at the time of bypass was 8.5 years (range, 0.4-14.2 years). Material used for bypass was as follows: left internal jugular vein (n = 20), recanalized umbilical vein (n = 2), gastric vein, and a large colic vein (n = 2). Median time since MPB is 8 years (range, 5.3-8.8 years). One MPB using recanalized umbilical vein thrombosed at 4 months but was successfully refashioned using Gortex. One MPB with left internal jugular vein was thrombosed at 1 year after cardiac surgery. Overall, 23 of 24 children have a patent bypass and resolution of portal hypertension. All show...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.

Cavernous Hemangioma

Cavernous hemangioma is a blood vessel defect or benign tumor that leads to leakage of blood to the surrounding tissues. This can occur in several organs including the brain, which can lead to seizures. Discover the latest research on cavernous hemangiomas here.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
