BACKGROUND Laparoscopic splenectomy has become an important therapeutic option in the management of diverse hematologic disorders. However, the incidence of important complications, such as portal vein thrombosis, remains poorly understood. We set out to study the incidence of this complication over a 14-month period. METHODS All adult patients who underwent laparoscopic splenectomy between J...

AIMS AND BACKGROUND The aim of this report was to investigate the feasibility in terms of treatment time prolongation of an on-line no-action level correction protocol, based on daily electronic portal image verification. METHODS AND STUDY DESIGN The occupation of a linear accelerator (LINAC) delivering 3-D conformal treatments was monitored for two weeks (from Monday to Friday, 10 working da...

We investigated flows of visitors migrating between different portal subpages. Two various portals were studied as weighted networks where nodes are portal subpages and edge weights are numbers of user transitions. Such networks differ from networks of portal subpages connected by hyperlinks prepared by portal designers. Distributions of link weights, node strengths, and times spent by visitors...

Pulmonary arterial hypertension with severe pulmonary vascular disease is a rare association of portal hypertension in man, be it the result of cirrhosis of the liver or obstruction of the portal vein. We induced portal hypertension in 23 rats by partially ligating the portal vein or by totally occluding it in two stages. The rats were killed between one and 15 months after operation. A collate...

arterioportal fistula after blunt hepatic trauma: case reports.plications associated with the use of peritoneal drains in liver traumas. Mandatory laparotomy for gunshot wounds penetrating the abdomen. Am. Objective. Results ofthe first prospective randomized clinical trial comparing partial and total portacaval shunt for variceal hemorrhage are reported. Summary Background Data. Total portacav...

The aim of the present study was to compare the effects of bone marrow-derived mesenchymal stem cells (BMSCs) transplanted via the portal vein or tail vein on liver injury in rats with liver cirrhosis. BMSCs were isolated from rat bone marrow and labeled with green fluorescent protein (GFP). Then, the labeled BMSCs were injected into rats with liver injury via the portal vein or tail vein. Two ...

Although transjugular intrahepatic portosystemic shunts are most frequently used for the management of portal hypertension, the surgical approach is preferred for symptomatic portal cavernoma cholangiopathy. We present the case of a 25-year old female patient with a portal cavernoma secondary to catheterization of the umbilical vein at birth. She had had two episodes of esophageal variceal blee...

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 ...

In this study we have examined blood flow in a model of the portal vein with and without obstructions to simulate conditions, which are common in liver diseases. We evaluated the impact of both conditions on the flow behaviour and found significant differences in the two models. Blockages, even when the flow conditions did not change, had an impact on the velocity magnitude, pressure, strain ra...

BACKGROUND Hepatobiliary cancer invading the hilar bile duct often involves the portal bifurcation. Portal vein resection and reconstruction is usually performed after completion of the hepatectomy. This retrospective study assessed the safety and usefulness of portal vein reconstruction prior to hepatic dissection in right hepatectomy and caudate lobectomy plus biliary reconstruction, one of t...
