Simple technique for transjugular intrahepatic portosystemic shunt reduction using a flared stent graft

摘要

Hepatic encephalopathy (HE) can develop as a result of diversion of portal venous flow away from the liver. HE has been reported in 20%-31% of patients after creation of a transjugular intrahepatic portosystemic shunt (TIPS) (1). Most of these patients respond favorably to conservative management. In a small subset of patients, HE remains refractory to medical treatment, requiring more invasive therapy. A preferred endovascular technique is one that reduces the size of the TIPS without causing total occlusion.
