目的:评价Szabo技术在介入处理冠脉开口部位病变中的安全性和可行性。方法:回顾性分析自2008年10月～2011年10月采用Szabo技术介入干预的16例冠心病患者,经冠脉造影提示病变符合Medina分类010/001分叉病变或者主动脉-开口部位病变。首先预扩张病变,在送入第1根导丝通过开口-分叉病变后,送第2根导丝作为锚定导丝,在体外穿过支架尾端最末网眼送入另一分支远段,支架近端沿第1根导丝送入病变处,由于锚定导丝作用便可成功精确定位于病变开口。所有患者术后跟踪随访3～12月,其中10例于术后半年进行冠脉造影复查。结果:所有16例患者中,15例成功采用Szabo技术精确定位释放支架,1例因血管局部钙化支架脱载改用常规方法后成功释放支架;所有病变中9例位于前降支开口,2例位于右冠开口,2例位于回旋支与钝缘支开口,2例位于右冠后降支与左室后侧支开口;术后跟踪随访3～12月均无心绞痛发作及其它心血管不良事件发生。结论:Szabo技术在介入处理冠脉开口部位病变中可以起到精确定位完全覆盖病变的作用,但对于钙化或弯曲病变将会增加支架脱载的风险。
Objective: To evaluate the safety and feasibility of Szabo technique in the treatment of coronary artery stenosis. Methods: A retrospective analysis of 16 patients with coronary artery disease treated with Szabo interventional intervention from October 2008 to October 2011 was performed. Coronary angiography showed that the lesions were in accordance with the Medina classification of 010/001 bifurcation lesions or aorta-opening lesions. First pre-dilated lesions, the first guide wire into the open-bifurcation lesions, send the second guide wire as an anchoring guide wire in vitro through the end of the stent last mesh into the other branch distal segment , The proximal stent along the first wire into the lesion, due to the role of the anchor wire can be successfully located in the precise positioning of the lesion. All patients were followed up 3 to 12 months after surgery, of which 10 were reviewed six months after coronary angiography. Results: In all 16 cases, 15 cases were successfully treated with Szabo technique and 1 case was successfully released by routine calcification. Nine cases were located in the anterior descending branch opening and 2 cases 2 cases were located in the circumflex and blunt limbal openings, 2 cases were located in the right posterior descending coronary artery and the posterior branch of the left ventricle. No angina pectoris and other cardiovascular adverse events were observed after follow-up from December to December occur. CONCLUSIONS: Szabo’s technique can be used to accurately cover and completely cover lesions in the interventional treatment of coronary ostial lesions. However, calcification or bending lesions may increase the risk of stent detachment.
