自发性门体分流是一种罕见的肝脏供血血管畸形。由于血液从门静脉过度分流至下腔静脉，这种情况常常导致肝性脑病的发生。一些研究表明，自发性门体分流的存在与大食管静脉曲张的出现呈负相关。自发性肝内门体分流 (SIPSS) 的发生率远远低于肝外门体分流，后者包括脾胃肾分流、肠系膜腔静脉分流和大的脐静脉开放。这里报道的是一例失代偿性肝硬化伴大 SIPSS，但没有发生任何明显的肝性脑病。
A spontaneous portosystemic shunt is a rare malformation of the vessels supplying the liver. This condition often leads to the development of hepatic encephalopathy due to excessive shunting of blood from the portal vein to the inferior vena cava. Some studies have suggested that the presence of spontaneous portosystemic shunts is inversely associated with the appearance of large esophageal varices. Spontaneous intrahepatic portosystemic shunts (SIPSS) are far less frequently observed than extrahepatic portosystemic shunts, which include spleno-gastric-renal shunts, mesenteric-caval shunts, and a large patent umbilical vein. Reported here is a case of decompensated liver cirrhosis with a large SIPSS without any incidence of overt hepatic encephalopathy.
