title: Endovascular therapy for hepatic artery stenosis and thrombosis following liver transplantation.
abstract: OBJECTIVE
  To evaluate the effectiveness of endovascular management of steno-oclusive disease in liver transplants.
  
  
  METHODS
  Retrospective review of liver transplant recipients with hepatic artery stenosis (HAS) or thrombosis (HAT) was performed. The HAS group was treated with balloon angioplasty with selective stent placement. The HAT group was treated with catheter-directed thrombolysis. Primary, unassisted, and assisted patency and graft survival rates were calculated.
  
  
  RESULTS
  In all, 31 patients were identified (21 males; mean age, 51 years). A total of 25 of 31 (81%) patients had HAS and 6 of 31 (19%) had HAT. Collectively, a total of 35 endovascular procedures were performed to treat HAS in 25 patients. Overall technical success rate was 91%, with 11% major complication rate. Primary-assisted patency rate and graft survival at 6 and 12 months were 87% and 81%, and 76% and 72%, respectively. Only 1 successful thrombolysis of HAT was achieved.
  
  
  CONCLUSIONS
  Endovascular management is effective for HAS but not for HAT.
