Intimal dissection of the hepatic artery after thrombectomy as a cause of graft loss in pediatric living-related liver transplantation

HAT is the main cause of graft loss in pediatric living-related LTx. Revascularization of the graft by thrombectomy and re-anastomosis has been reported to be effective for graft salvage in cases of HAT and should be attempted when potential donors are not available for emergency re-transplantation. Immediate complications secondary to revascularization attempts in cases of HAT are not described. Late complications are mainly related to biliary tree ischemia. We report a case of child who experienced intimal hepatic artery dissection, which extended into intra-hepatic branches of the artery after a thrombectomy with a Fogarty balloon catheter in an attempt to restore arterial flow after HAT. This complication led to acute deterioration of the graft and the need for emergency re-transplantation.
