title: Splenic artery ligation in distal splenorenal shunts.
abstract: Splenic artery ligation, a simple surgical procedure expected to decrease splenic flow and portal pressure in patients with cirrhosis of the liver, was performed concomitantly with a distal splenorenal shunt procedure in six patients and as the main surgical procedure in two patients. Immediate cessation of bleeding was achieved in the four patients in whom the splenic artery was ligated to reduce intraoperative bleeding. However, three of the seven patients with previous gastroesophageal hemorrhage rebled from various postoperatively. Symptoms of splenic infarction were observed in six patients, resulting in thrombosis of the splenic vein and/or of the distal splenorenal shunt in four patients and necessitating splenectomy in one. This incidence of thrombosis of the distal splenorenal shunt is much higher than the overall incidence of 5 per cent observed at our institution. It is thus concluded that the splenic artery should not be ligated in cirrhotic patients with patent distal splenorenal shunts, since splenic arterial collateral vessels have already been reduced by the gastric devascularization, an integral component of the distal splenorenal shunt.
