Embolization therapy for bleeding from jejunal loop varices due to extrahepatic portal vein obstruction

Abstract

Four patients underwent embolization therapy for hemorrhage from varices in the jejunal loop after choledochojejunostomy existing in hepatopetal collateral veins due to chronic extrahepatic portal vein obstruction through the afferent veins using microcoils and/or n-butyl cyanoacrylate. In all four patients, all afferent veins were successfully embolized and successful hemostasis was achieved without liver dysfunction. However, recurrence of the varices and rebleeding occurred within a year in two patients. Embolization for hemorrhage from varices in the jejunal loop after choledochojejunostomy through afferent veins is acceptable in terms of safety and is useful to achieve hemostasis in emergencyt circumstances.

Key words:

• Embolization
