چکیده

ied in twelve patients undergoing taparotomy without liver disease. Liver scintigrams were obtained following injection of tracer doses of 198Aucolloj@ into a mesenteric vein and corn pared with repeat scintigrams obtained follow ing i.v. injection of ssmTc.rnicroaggregated albumin. Particularly from subdivisions of the superior rnesenteric vein, portal vein blood is directed predominantly to the right lobe. This may explain the predominance of right lobe in volvement in infectious diseases which ernbolize to the liver via the superior mesenteric vein.

Are hepatic portal venous system components distributed equally in the liver? A multidetector computerized tomography study.

OBJECTIVE We aimed to evaluate the relationships between the splenic index, right and left hepatic lobe volumes, diameters of splenic vein (SV), superior mesenteric vein (SMV) and the portal vein (PV) by Multidetector Computerized Tomography (MDCT). We also investigated indirect signs of portal venous flow pattern using these parameters. MATERIAL AND METHODS Following their contrast thoracoab...

Intrahepatic ramifications of the portal vein in the horse

The ramifications of the portal vein in the liver of horses were studied by using corrosion casting and gross dissection. The portal vein in the horse supplies the hepatic lobes by six major branches. The right lobe is supplied by three main branches, namely the dorsal diaphragmatic, the right caudodorsal and the right intermediate branches. The left branch supplies the left lateral and medial ...

Streamline flow of the portal vein affects the lobar distribution of colorectal liver metastases and has a clinical impact on survival

PURPOSE It is believed that blood from the superior mesenteric vein and splenic vein mixes incompletely in the portal vein and maintains a streamline flow influencing its anatomic distribution. Although several experimental studies have demonstrated the existence of streamlining, clinical studies have shown conflicting results. We investigated whether streamlining of portal vein affects the lob...
