We report the case of a 64-year-old man treated for stable angina with two bare-metal stents in the proximal-mid segment of the left anterior descending artery at the bifurcation with the first diagonal and second septal branches without final kissing balloon dilatation. Seven months later he complained of recurrent angina. Frequency-domain optical coherence tomography (OCT) with three-dimensional (3D) reconstruction was performed, showing a thick rim of neointimal proliferation at the ostium of both branches, causing severe restenosis. Deployment of a stent in a bifurcation main branch without opening the struts at the side-branch ostium may facilitate focal restenosis.
我们报告了一例 64 岁男性患者的病例，该患者因稳定型心绞痛，在左前降支近段-中段与第一对角支和第二间隔支分叉处接受了两个金属裸支架治疗，未进行最终的对吻球囊扩张。7 个月后，他主诉心绞痛复发。进行频域光学相干断层扫描（OCT）三维（3D）重建，显示两支开口处有新生内膜增生的厚边缘，导致严重的再狭窄。在分叉主干内放置支架而不打开分支开口处的支架可能会导致局部再狭窄。
