Transhepatic Embolization of a Recanalized Congenital Hepatic Arterioportal Fistula with NBCA and Coils

摘要

Congenital hepatic arterioportal fistula is a treatable cause of portal hypertension. Transarterial embolization is a widely accepted endovascular treatment approach. Here, a case of a recanalized congenital hepatic arterioportal fistula after prior transarterial coil embolization that was successfully treated with percutaneous transhepatic embolization with coils and N-butyl 2-cyanoacrylate is reported. The percutaneous transhepatic approach can be an effective alternative for patients with recanalized hepatic arterioportal fistula who have undergone prior transarterial coil embolization, and N-butyl 2-cyanoacrylate can be used as an embolic material in addition to metallic coils to achieve quick and total occlusion.
