The use of coronary stent in hepatic artery stenosis after orthotopic liver transplantation.

PURPOSE: This retrospective study was undertaken to evaluate the effectiveness of coronary stent placement in hepatic artery stenosis after orthotopic liver transplantation (OLT).
MATERIALS AND METHODS: Of 430 consecutive adult orthotopic liver transplant recipients between November 2003 and September 2005, 17 had hepatic artery stenosis (HAS). Fourteen of them underwent coronary stent placement in the HAS. The technical results, complications, hepatic artery patency and clinical outcome were reviewed.
RESULTS: Technical and immediate success was 100%. After a mean follow-up of 159.4 days (range, 9-375 days), all patients obtained patent hepatic arteries except 2 patients occurred hepatic artery restenoses at 26 and 45 days after stent placement, respectively. Kaplan-Meier curve of patency showed cumulated stent patency at 3, 6, and 12 months of 78%, 58% and 45%, respectively. During the follow-up, 8 patients survived, 5 died of septic multiple-organ failure, 1 received retransplantation because of refractory biliary infection. Hepatic artery dissection induced by a guiding catheter occurred in one patient and was successfully treated with a coronary stent.
CONCLUSION: Hepatic artery stenosis after OLT can be successfully treated with coronary stent placement with low complication rate and an acceptable 1-year hepatic artery patency rate.
