目的:探讨冠状动脉左主干开口病变支架置入术的安全性及疗效。方法:分析11例左主干开口病变患者行支架置入术的成功率及随访结果。结果:11例患者支架置入术即刻成功率为100%,无残余狭窄或残余狭窄率<10%,无严重术中并发症。随访6～12个月,无亚急性或延迟性支架内血栓形成;临床心绞痛复发1例;6例行冠状动脉造影复查,未发现支架内再狭窄。结论:支架置入术治疗左主干开口病变疗效明显,并发症及再狭窄率低,是一种安全有效的治疗方法。
Objective: To investigate the safety and efficacy of stent implantation in patients with left main coronary artery stenosis. Methods: The success rate and follow-up results of 11 cases of left main open lesions underwent stent implantation were analyzed. Results: Immediate success rate of stent implantation was 100% in 11 patients. No residual stenosis or residual stenosis rate was less than 10%. There was no serious intraoperative complications. Followed up for 6 to 12 months, no subacute or delayed stent thrombosis; 1 case of clinical angina recurrence; 6 cases underwent coronary angiography, found no in-stent restenosis. Conclusion: Stent placement is a safe and effective treatment for the left main open lesions with obvious curative effect and low complication and restenosis rate.
