我们描述了使用定向斑块旋切术（DA）来恢复血栓形成的聚四氟乙烯动静脉移植物的通畅，并在静脉吻合处进行支架内再狭窄。从技术上讲，所描述的手术本身并不是粥样斑块切除术，而是通过尖锐的腔内解剖去除纤维化和内膜增生。当然，操作员在直接邻近先前部署的支架进行 DA 时必须小心谨慎。尽管如此，我们的报告表明 DA 可能在治疗严重、难治性支架内狭窄方面发挥作用。需要进一步研究来评估所描述技术的安全性和有效性。
We describe the use of directional atherectomy (DA) to restore patency of a thrombosed polytetrafluoroethylene arteriovenous graft with an in‐stent restenosis at the venous anastomosis. Technically, the procedure described is not an atherectomy per se, but rather the removal of fibrosis and intimal hyperplasia with sharp endoluminal dissection. Certainly, the operator must be cautious when performing DA directly adjacent to a previously deployed stent. Nevertheless, our report suggests that there may be a role for DA in the treatment of severe, resistant in‐stent stenosis. Further investigation is necessary to evaluate the safety and efficacy of the described technique.
