Abstract

Objectives: To report the experience of a high-volume center with balloon-expandable (BE) stents implantation to manage vascular complications after transcatheter aortic valve replacement (TAVR).

Background: Despite increased operator experience and better devices, vascular complications after TAVR are still a major issue and covered stent implantation is often required.

Methods: We retrospectively collected baseline and procedural data about 78 consecutive patients who underwent BE stent implantation to manage a vascular complication after transfemoral TAVR. Primary endpoints were technical success, incidence of new-onset claudication and need for vascular interventions during long-term follow-up. Secondary endpoints included length of hospitalization, in-hospital and 30-day mortality, and major postoperative complications.

Results: BE stents implantation to manage vascular complications after TAVR was successfully performed in 96.2% of the cases, with bailout surgery required in two cases. One patient suffered in-hospital death. Predischarge Doppler Ultrasound revealed no cases of in-stent occlusion or fracture. At a median follow-up of 429 days (interquartile range, 89-994 days), no cases of symptomatic leg ischemia were reported and only one patient experienced new-onset claudication.

Conclusions: Our experience showed good periprocedural and long-term results of BE covered stent implantation to manage vascular complication after TAVR. Their great radial outward force may guarantee effective hemostasis without necessarily being associated with stent deformation/fracture resulting in restenosis or further interventions. More research is needed to define the role of BE covered stents in this setting.

摘要

研究目的：报告一家高手术量医疗中心采用球囊扩张式（balloon-expandable, BE）覆膜支架治疗经导管主动脉瓣置换术（transcatheter aortic valve replacement, TAVR）后血管并发症的临床经验。

研究背景：尽管术者操作经验不断提升、器械性能持续优化，但TAVR术后血管并发症仍是临床亟待解决的重要问题，覆膜支架植入常为必要治疗手段。

研究方法：本研究回顾性收集了78例因经股动脉TAVR术后出现血管并发症而接受BE覆膜支架植入的连续患者的基线资料与手术数据。主要终点包括技术成功率、新发跛行发生率以及长期随访期间血管干预的必要性；次要终点包括住院时长、院内及30天死亡率，以及术后主要并发症。

研究结果：96.2%的病例成功实施了TAVR术后血管并发症的BE覆膜支架治疗，仅2例需行补救性外科手术。1例患者发生院内死亡。出院前多普勒超声检查未发现支架内闭塞或支架断裂病例。中位随访时间为429天（四分位间距：89~994天），未报告症状性下肢缺血病例，仅1例患者出现新发跛行。

研究结论：本中心的临床经验表明，BE覆膜支架治疗TAVR术后血管并发症的围手术期及长期预后良好。其优异的径向向外支撑力可有效实现止血，且未必会引发支架变形/断裂，进而导致再狭窄或需进一步临床干预。未来仍需开展更多研究以明确BE覆膜支架在该临床场景中的应用价值。
