Abstract
Obliteration of portal-systemic shunts is effective for portosystemic encephalopathy but is often associated with complications such as retention of ascites and worsening of esophageal varices. Selective embolization of the splenic vein was performed on six patients with hepatic encephalopathy and splenorenal shunts. Hepatic encephalopathy was not observed in four patients after the procedure. Neither retention of ascites nor rupture of esophageal varices was observed because postoperative elevation of portal venous pressure was not as great as that seen when shunt obliteration is performed. This procedure can be an effective and safe treatment option for hepatic encephalopathy with a splenorenal shunt.
