Interventional treatment of hepatic artery stenosis after orthotopic liver transplantation with balloon-expandable coronary stent.

Objective: The aim of this study was to evaluate the efficacy of hepatic artery stenting with a balloon-expandable coronary stent for the treatment of hepatic artery stenosis (HAS) after orthotopic liver transplantation (OLT).
Patients and Methods: We performed retrospective review of all 11 patients who underwent hepatic artery stenting after a diagnosis of HAS.
Results: A total of 13 balloon-expandable coronary stents were placed into 11 patients. The technical and immediate success rate was 100%; all stents remained patent during follow-up. One patient required 2 stents due to the length of the stenotic artery. Another underwent a second stenting after developing restenosis proximal to the original stenotic site. No procedure-related complications occurred, and no surgical revascularization or retransplantation was required during follow-up.
Conclusions: A balloon-expandable coronary stent can play a role in the management of HAS. It can be used with great safety, with immediate as well as longer-term success.
