Indigo Thrombectomy System for Hepatic Artery Thrombosis After Liver Transplantation: A Case Report

Introduction. Hepatic artery thrombosis still represents a major complication after liver transplantation responsible for graft failure, possibly resulting in the need for retransplantation. Case Report. We describe a case of a patient undergoing liver transplant complicated by hepatic artery thrombosis, successfully treated with an endovascular approach using the Indigo System. This new system allows mechanical fragmentation and aspiration of the thrombus, with no injection of any thrombolytic agents, thereby reducing the risk of bleeding. Hepatic artery flow was immediately restored, with no complications for the patient and the graft. Discussion. The Indigo System appears to be a safe, affordable, and manageable technique for endovascular management of late hepatic artery thrombosis after liver transplant.
