This study aimed to report a modification to the single-needle pass technique by use of a portal vein localization sheath for creation of a portosystemic shunt. The modification makes the single-needle pass technique a more straightforward procedure.

RATIONALE Portal vein thrombosis is a complication after liver transplantation and cavernous transformation of the portal vein (CTPV) is a result of portal vein thrombosis, with symptoms of portal hypertension revealed by an enhanced CT scan. Meso-Rex bypass is an artificial shunt connecting the left portal vein to the superior mesenteric vein and is mainly used for idiopathic cavernomas. This ...

UNLABELLED Our objective was to investigate the diagnostic value and clinical significance of transsplenic portal scintigraphy in cirrhotic portal hypertension and compensatory circulation. METHODS Transsplenic portal scintigraphy, ultrasound, and gastroscopy were performed on 50 patients with cirrhotic portal hypertension and on 10 controls. According to the Child-Pugh classification, 15 pat...

Portal biliopathy refers to cholangiographic abnormalities which occur in patients with portal cavernoma. These changes occur as a result of pressure on bile ducts from bridging tortuous paracholedochal, epicholedochal and cholecystic veins. Bile duct ischemia may occur due prolonged venous pressure effect or result from insufficient blood supply. In addition, encasement of ducts may occur due ...

INTRODUCTION The recipient of an adult living donor liver transplant (ALDLT) is subjected to great haemodynamic changes that could lead to the appearance of a "small-for-size" syndrome in the post-operative period due to portal hyperflow. The aim of this article is to evaluate these changes, and try to correlate them with portal vein flow during reperfusion. MATERIAL AND METHODS A protocol fo...

Portal hypertension has been regarded as an uncommon and late complication of primary biliary cirrhosis (PBC). 24 patients with PBC were investigated for portal hypertension. Esophageal varices were present in 20, 50, and 90% of the patients 1, 3, and 9 years, respectively, after the onset of pruritus and/or jaundice. Portal hypertension was responsible for gastrointestinal bleedings in 11 pati...

In all species so far studied, including man, portacaval shunt causes the same changes in liver morphology, including hepatocyte atrophy, fatty infiltration, deglycogenation, depletion and disorganization of the rough endoplasmic reticulum (RER) and its lining polyribosomes, and variable but less specific damage to other organelles. Many, perhaps all, biosynthetic processes are quickly depresse...

Hepatic arterioportal fistulae are a rare cause of portal hypertension. The case is reported of a two-year old girl with a congenital arterioportal fistula, who presented with splenomegaly and ascites. Colour doppler ultrasound showed a large shunt between the left hepatic artery and a branch of the left portal vein, producing a reversal of flow in the main portal vein. She was treated by a for...

This report describes two non-cirrhotic patients with portal vein thrombosis who underwent successful balloon occlusion retrograde transvenous obliteration (BRTO) of gastric varices with a satisfactory response and no complications. One patient was a 35-year-old female with a history of Crohn's disease, status post-total abdominal colectomy, and portal vein and mesenteric vein thrombosis. The o...
