BACKGROUND After portal vein ligation of 1 side of the liver, the other side regenerates at a slow rate. This slow growth may be accelerated to rapid growth by adding a transection between the 2 sides, i.e., performing portal vein ligation and parenchymal transection. We found that in patients undergoing portal vein ligation and parenchymal transection, portal vein hyperflow in the regenerating...

BACKGROUND/AIMS/METHODS During hepatic vein catheterisation, in addition to measurement of hepatic venous pressure gradient (HVPG), iodine wedged retrograde portography can be easily obtained. However, it rarely allows correct visualisation of the portal vein. Recently, CO(2) has been suggested to allow better angiographic demonstration of the portal vein than iodine. In this study we investiga...

OBJECTIVE To describe the appearance of transient hepatic attenuation differences (THADs) of extrahepatic origin. MATERIALS AND METHODS Five cases of THADs produced by compression of the extrahepatic portal vein at its confluence with the splenic vein were identified prospectively over a four-month period. Two additional cases of peripheral THADs resulting from main portal vein thrombosis wer...

Portal vein thrombosis is observed in up to 10% of liver transplant candidates, hindering execution of the procedure. A dilated gastric vein is an alternative to portal vein reconstruction and decompression of splanchnic bed. We present two cases of patients with portal cavernoma and dilated left gastric vein draining splanchnic bed who underwent liver transplantation. The vein was dissected an...

Pathologic changes of the recipient native portal venous system may cause thrombosis of the portal vein, especially in pediatric living donor liver transplantation (LDLT). This study assessed the utility of Doppler ultrasound (US) for the detection of intraoperative portal vein occlusion and identification of predisposing risk factors in the recipients. Seventy-three pediatric recipients who un...

Objective- This survey was accomplished to describe the hepatic artery and portal vein indices in healthy domestic cats by color Doppler ultrasonography technique. Design- Retrospective experimental study. Animals- Twenty domestic short hair (DSH) cats (10 males and 10 females). Procedures- Doppler indices of ...

tor of the liver was identified as an aberrant coronary vein ( fig. 1 ). A superior mesenteric arterioportogram revealed portal vein obstruction, resulting in portal blood flowing back to the right gastroepiploic and splenic veins. Venous blood of the lesser curvature then drained into the left portal system via the aberrant coronary vein ( fig. 2 ). Cavernous transformation of the portal vein ...

We examined 27 resin casts of foetal liver veins and found three types of connection between portal vein and portal sinus. The most frequent connection was endo-lateral (66.7%), when the end of the portal vein joins with the lateral wall of the portal sinus. The next type was latero-lateral (14.8%). In this type, the lateral walls of the portal sinus and the portal vein join together. The last ...

BACKGROUND Mean portal vein diameter is considered as the best indicator for portal hypertension. However, the cutoff point differs from study to study (above 10-15 mm) despite the existence of normal mean portal vein diameter between 10-15 mm in different settings.This implies the existence of limited evidence on normal portal vein diameter for all populations in all countries prior to setting...

BACKGROUND/AIMS In liver anatomy and surgery, is portal and hepatic vein segmentation (French segmentation) to be preferred over arteriobiliary segmentation (Healey and Schroy, North American segmentation)? METHODS Several embryological arguments and an analysis of anatomical data from a personal collection of 110 vasculobiliary casts were made. RESULTS Embryological arguments: Portal vein ...
