Super selective percutaneous transhepatic coil embolization of intrahepatic pseudoaneurysm after pediatric liver transplantation: a case report

摘要

Percutaneous transhepatic coil embolization. a Angiogram of the segment III liver artery using the coaxial technique (macrocatheter: arrowhead; microcatheter: curved arrow) prior to embolization shows localization and configuration of pseudoaneurysm (black arrows) as well as irregularity of the segment III liver artery due to vasospasm. b Fluoroscopy after percutaneous transhepatic access and embolization of the pseudoaneurysm (black arrow) via the CHIBA needle (white arrows) delineates coils within the pseudoaneurysm. The microcatheter (curved arrow) was advanced into a side branch of S III artery distal to the pseudoaneurysm to avoid coil dislodgement
