Peri-stent vascular channels after transjugular intrahepatic portosystemic shunt placement for Budd–Chiari syndrome: CT and US findings

Abstract

Transjugular intrahepatic portosystemic shunt (TIPS) placement has been used as a bridge to transplantation in patients with Budd–Chiari syndrome. Stent occlusion is a fairly common but seldom described complication after TIPS placement for Budd–Chiari syndrome. I present a case of a patient with Budd–Chiari who developed vascular channels paralleling an occluded stent. These channels were demonstrated only by power Doppler ultrasound and resulted in an unusual transient hepatic attenuation difference around the stent on computed tomography.
