Portal-to-right portal vein bypass for extrahepatic portal vein obstruction

Journal of Pediatric Surgery, 2018
Rex shunt (mesenteric-to-left portal vein bypass) is considered a more physiologically rational treatment for EHPVO than other portosystemic systemic shunts in children. However, about 13.6% of children with EHPVO do not have usable left portal veins and up to 28.1%. Rex operations in children are not successful.

Extrahepatic Portal Vein Obstruction

Seminars in Liver Disease, 2002
Extrahepatic portal vein obstruction (EHPVO) is an important cause of noncirrhotic portal hypertension, especially in Third World countries. The etiology and clinical presentation are different in children and adults. The portal vein is transformed into a cavernoma, resulting in portal hypertension and oesophagogastic varices.

Extrahepatic Portal Vein Thrombosis

Seminars in Liver Disease, 2008
Noncirrhotic, nontumoral portal vein thrombosis (PVT) is the second most-frequent cause of portal hypertension in the world. General thrombophilic factors can be identified in approximately 60% of patients. PVT may manifest as an acute process. However, the acute episode more frequently is asymptomatic or paucisymptomatic and portal vein thrombosis is ...

CONGENITAL PREDUODENAL PORTAL VEIN

American Journal of Roentgenology, 1971
Preduodenal portal vein may occur as an isolated event and result in no symptoms, or be found at autopsy as an incidental finding. It is much more likely to be part of an anomaly complex.The clinical-roentgenologic correlation of the following features should suggest preduodenal portal vein:1. Visceral malrotationa. dextrocardiab. small and large bowel
