We investigated the effect of splenomegaly on portal hemodynamics during and after distal splenorenal shunt with splenopancreatic disconnection in 27 patients with nonalcoholic cirrhosis (13 with and 14 without splenic enlargement). Data were obtained by Doppler flowmetry, electromagnetic flowmetry and computed tomographical scanning. The splenomegaly group had a significantly higher preoperative splenic and portal blood flow than the nonsplenomegaly group. In both groups, postoperative portal venous pressure did not fall; portal blood flow significantly decreased while splenic volume was reduced, despite the lack of significant changes in splenic venous blood flow. There was a greater reduction of portal blood flow with previous splenomegaly than with normal-sized spleens, and this was not related to the degree of reduction in liver volume. In the splenomegaly group, the increase of splenic blood flow was only present during the early postoperative period. In conclusion, distal splenorenal shunt with splenopancreatic disconnection influenced portal hemodynamics differently in nonalcoholic cirrhotic patients with and without splenomegaly.

D008103 Liver Cirrhosis Liver disease in which the normal microcirculation, the gross vascular anatomy, and the hepatic architecture have been variably destroyed and altered with fibrous septa surrounding regenerated or regenerating parenchymal nodules. Cirrhosis, Liver,Fibrosis, Liver,Hepatic Cirrhosis,Liver Fibrosis,Cirrhosis, Hepatic
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D010179 Pancreas A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
D011169 Portal Vein A short thick vein formed by union of the superior mesenteric vein and the splenic vein. Portal Veins,Vein, Portal,Veins, Portal
D011170 Portasystemic Shunt, Surgical Surgical venous shunt between the portal and systemic circulation to effect decompression of the portal circulation. It is performed primarily in the treatment of bleeding esophageal varices resulting from portal hypertension. Types of shunt include portacaval, splenorenal, mesocaval, splenocaval, left gastric-caval (coronary-caval), portarenal, umbilicorenal, and umbilicocaval.
