RESUMEN
The consequence of an acute mesenteric venous thrombosis following porta-azygos disconnection for the treatment of bleeding esophageal varices due to mansonian schistosomiasis has not been well defined in the literature. The clinical manifestations reported were fever, spasmodic abdominal pain associated with food intake. We treated three patients with thrombosis of the portal-mesenteric trunk following porta-azygos disconnection and adopted a conservative clinical approach in two patients while one had to have a surgical small bowel ressection.

It is possible to obtain two good-quality hepatic transplants from a single cadaveric liver by separation of the right and left lobes of the liver. We attempted to define a relationship based only on donor body weight for predicting donor total liver weight as well as donor right (segments V-VIII) and left (segments II-IV) hepatic lobe weight. Segment I (caudate lobe) is resected and thus lost in this procedure. The study was performed on 60 human cadaveric livers. We correlated cadaveric body weight (mean +/- SD), 72.43 +/- 9.54 kg, with total liver weight, 1.54 +/- 0.36 kg, and right and left lobe weight, 0.88 +/- 0.23 kg and 0.65 +/- 0.17 kg, respectively, with total liver weight. A formula was obtained by linear regression which provided the following relationships: total liver weight (g) = [245.57 + 17.92 x (body weight, kg)]; right lobe weight (g) = [67.58 + 0.52 x (total liver weight, g)]; left lobe weight (g) = [-63.38 + 0.47 x (total liver weight, g)]. The selection of the recipient on the liver transplant waiting list can be made on the basis of these relationships.

Sixty fresh adult livers were obtained from cadavers together with celiac trunk, head of the pancreas and superior mesenteric artery. The right portal vein, left portal vein and their respective branches were dissected as well as the hepatic veins. There was only one right hepatic vein in 59 cases. The median hepatic vein was present in 53 (88.3%) cases and the left hepatic vein only in 46(76.3%). In 59(98.3%) cases, there were right and left portal vein but in one (1.6%) case no portal bifurcation has been found. The median portal vein has been found only in 9(15.2%) cases.
