Portal Vein Aneurysm Treated With Trans-Jugular Intrahepatic Porto-Systemic Shunt.

Portal vein aneurysm (PVA) is a rare entity that can lead to hemorrhage or thrombosis. Although there is no standard treatment, most cases can be managed conservatively; intervention is reserved for symptomatic or enlarging aneurysms. For patients who are not surgical candidates due to cirrhosis and portal hypertension, endovascular creation of a trans-jugular intrahepatic porto-systemic shunt (TIPS) is an option to reduce portal venous pressure. This report describes a case of an enlarging PVA successfully treated with TIPS in a patient with cryptogenic cirrhosis.
