冠状动脉左主干急性闭塞介入治疗新术式临床应用

目的 探讨冠状动脉左主干急性闭塞病变介入治疗新术式临床应用的效果.方法 收集2003年5月至2016年10月收治的左主干急性闭塞患者58例临床资料.其中14例接受传统经皮冠状动脉介入治疗(PCI),44例先接受小球囊扩张,血流恢复TIMI分级3级后等待30～40 min再植入支架.结果 接受传统PCI治疗患者中8例死亡,死亡率为57.1％(8/14);接受先行小球囊扩张再行支架植入术患者中仅3例死亡,死亡率为6.8％(3/44).结论 小球囊扩张后延时支架植入术治疗急性左主干闭塞患者死亡率更低,是一种安全有效的术式.

The clinical application of a new interventional therapy for acute left main coronary artery occlusion

Objective To investigate the curative effect of a new interventional therapy for acute left main coronary artery occlusion.Methods The clinical data of a total of 58 patients with acute left main coronary artery occlusion,who were admitted to authors' hospital during the period from May 2003 to October 2016 to receive treatment,were retrospectively analyzed.Among the 58 patients,14 patients underwent traditional percutaneous coronary intervention (PCI group),and 44 patients (combination treatment group) received small balloon expansion first,and subsequent stent implantation was carried out in 30-40 min after the coronary blood flow restored to grade Ⅲ of TIMI classification.Results In PCI group,8 patients died,the mortality was 57.1％(8/14).In combination treatment group,only 3 patients died,the mortality was 6.8％ (3/44).Conclusion For the treatment of acute left main coronary artery occlusion,combination use of small balloon expansion and subsequent stent implantation is a safe and effective therapy with lower mortality.
