摘要
目的:评价逆向技术在慢性冠状动脉完全闭塞病变(CTO)介入治疗中应用的可行性及安全性。方法:3例经造影证实的CTO,均有另一支冠状动脉向远端血管提供良好侧枝循环,造影时CTO血管由远及近逆向显影。正向技术失败后,使用双指引导管法,逆向联合应用微导管和不同CTO专用导丝,导丝通过CTO病变后,继续进入正向指引导管内进行球囊扩张锚定,行逆向球囊扩张,正向导丝通过病变,植入支架。结果:3例成功通过逆向技术植入支架,术中无冠状动脉夹层及穿孔并发症情况。结论:逆向联合应用微导管、CTO专用导丝及逆向球囊扩张技术在冠状动脉慢性完全闭塞病变(CTO)介入治疗中应用具有一定的可行性及安全性。
Objectives： To evaluate the feasibility and security of applying retrograde technique in the interventional treatment for chronic total coronary occlusion（CTO） lesions.Methods：We elected 3 cases of chronic total coronary occlusion（CTO） patients confirmed by coronary angiography（CAG） via radial artery whcih all exist collateral circulations with another coronary artery at the distal portion whose coronary angiographies（CAG） suggested the images developed from distal to proximal portion.During the interventional operations,as the previously failed antegrade double guiding catheters,microcatheters and different special Guidings for chronic total coronary occlusion（CTO） and accuratelypercutaneous coronary intervention（PCI）,we tried to get through the occlusion lesions by the retrograde combined application of controlling directions of the guides wires,then performed balloon dilatation anchoring through antegrade guiding catheter and retrograde balloon dilatation,implanted and expanded sents successfully,when antegrade guide wire passed the lesion.Results：Percutaneous coronary intervention（PCI） have been performed successfully for 3 cases of chronic total coronary occlusion（CTO） patients,without coronary dissection and perforation.Conclusions：The retrograde technique is an ideal technique in the interventional treatment for chronic total coronary occlusion（CTO） lesions.
