Interventional Treatment of Hepatic Artery Stenosis After Orthotopic Liver Transplantation With Balloon-Expandable Coronary Stent

ObjectiveThe 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 MethodsWe performed retrospective review of all 11 patients who underwent hepatic artery stenting after a diagnosis of HAS.ResultsA 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.ConclusionsA 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.
