Iatrogenic left vertebral artery pseudoaneurysm treated with a covered stent.

Catheter directed hepatic artery thrombolysis following liver transplantation. Case report and review of the literature.

Hepatic artery thrombosis is the most frequent vascular complication following orthotopic liver transplantation, and often results in biliary complications, early graft loss and death. Surgical revascularization and retransplantation are considered the mainstay of treatment. However, intraarterial endovascular therapy is an alternative that has shown low morbidity and mortality, thereby avoiding the need for retransplantation.
