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).
We performed retrospective review of all 11 patients who underwent hepatic artery stenting after a diagnosis of HAS.
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.
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.
本研究旨在评估使用球囊扩张式冠状动脉支架进行肝动脉支架置入术治疗原位肝移植（OLT）后肝动脉狭窄（HAS）的疗效。
我们对所有11例诊断为HAS后接受肝动脉支架置入术的患者进行了回顾性研究。
共对11例患者置入了13枚球囊扩张式冠状动脉支架。技术成功率和即刻成功率均为100%；随访期间所有支架均保持通畅。1例患者因狭窄动脉长度原因需要2枚支架。另1例在原狭窄部位近端出现再狭窄后接受了二次支架置入术。未发生与手术相关的并发症，随访期间无需进行外科血管重建或再次移植。
球囊扩张式冠状动脉支架可用于HAS的治疗。其使用安全性高，即刻及长期成功率均较高。
