Acute stent recoil and luminal filling defects can result in a suboptimal angiographic result following stent deployment and are associated with an increased risk of adverse outcomes. We aimed to evaluate the effect of double stenting, deployment of a second stent within the first, in the treatment of these conditions and to review the literature on this procedure.
Thirteen cases of double stenting performed by a single operator at the Manchester Royal Infirmary over a three year period were identified and quantitative coronary angiography was performed. The indication for double stenting was acute stent recoil in eight cases, luminal filling defects in three cases and a combination of recoil and filling defects in two cases. There was a high frequency of target vessel calcification (77%) and ostial lesions (23%). Following double stenting, mean minimum lumen diameter increased significantly from 2.5 mm to 3.5 mm (p <0.001). There were no procedural complications. At mean clinical follow-up of 19 months (range six to 37 months), there were no major adverse cardiac events.
Double stenting can significantly improve angiographic outcome in cases of acute stent recoil and luminal filling defects, with excellent clinical results in the medium term.
急性支架回缩和管腔充盈缺损可导致支架置入后血管造影结果不理想，并增加不良结局的风险。我们旨在评估在这些情况下双支架置入术（即在第一个支架内再置入一个支架）的治疗效果，并对该手术的文献进行综述。
在三年期间，一名术者在曼彻斯特皇家医院共进行了 13 例双支架置入术，所有患者均进行了定量冠状动脉造影。双支架置入术的适应证为 8 例急性支架回缩、3 例管腔充盈缺损和 2 例支架回缩合并充盈缺损。病变处存在较高频率的靶血管钙化（77%）和开口病变（23%）。双支架置入术后，平均最小管腔直径从 2.5mm 显著增加至 3.5mm（p<0.001）。无手术相关并发症。平均临床随访 19 个月（6 至 37 个月），无主要不良心脏事件。
双支架置入术可显著改善急性支架回缩和管腔充盈缺损患者的血管造影结果，且中期临床结果良好。
