[Successful emergency superselective embolization for hemobilia with a new coaxial catheter and steerable guidewire].

Abstract

Hemobilia occurred in a 70 year old female from the left hepatic artery pseudoaneurysm induced by PTBD. A Tracker-18 catheter introduced into the left lateral posterior hepatic artery superselectively and embolization was performed with both sponge gel and Ivalon. This new coaxial catheter system allowed selective occlusion of the hepatic artery pseudoaneurysms with minimal loss of liver function.
