The collateral caval shunt as an alternative to classical shunt procedures in patients with recurrent duodenal varices and extrahepatic portal vein thrombosis

Upper gastrointestinal bleeding episodes from variceal structures
are severe complications in patients with portal hypertension.
Endoscopic sclerotherapy and variceal ligation are the treatment
options preferred for upper variceal bleeding owing to extrahepatic
portal hypertension due to portal vein thrombosis (PVT). Recurrent
duodenal variceal bleeding in non-cirrhotic patients with diffuse
porto-splenic vein thrombosis and subsequent portal cavernous
transformation represent a clinical challenge if classic shunt
surgery is not possible or suitable. In this study, we represent a
case of recurrent bleeding of duodenal varices in a non-cirrhotic
patient with cavernous transformation of the portal vein that was
successfully treated with a collateral caval shunt operation.
