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.
