This report describes a case of successful percutaneous coronary transluminal angioplasty (PTCA) of a coronary artery bifurcating lesion using multiple intracoronary stents in an inverted 'Y' configuration. Balloon angioplasty of bifurcation coronary stenoses has a lower procedural success rate, higher restenosis rate and potential for side branch occlusion compared with nonbifurcation lesions. Numerous techniques, including two ('kissing') angioplasty balloons, have been used to overcome these problems. The authors believe that the technique described in this report, inserting stents into both branches simultaneously followed by a third proximal stent in a 'Y' configuration, allows successful dilatation of the bifurcation lesion while preserving flow into both branches and should be considered for similar complex anatomical subsets.
本报告描述了一例使用多个呈倒“Y”形配置的冠状动脉内支架对冠状动脉分叉病变成功进行经皮冠状动脉腔内血管成形术（PTCA）的病例。与非分叉病变相比，冠状动脉分叉狭窄的球囊血管成形术手术成功率较低、再狭窄率较高且有侧支闭塞的可能性。包括双（“亲吻”）血管成形术球囊在内的多种技术已被用于克服这些问题。作者认为，本报告中描述的技术，即同时在两个分支中插入支架，随后在“Y”形配置中插入第三个近端支架，能够在保留两个分支血流的同时成功扩张分叉病变，对于类似的复杂解剖亚组应予以考虑。
