左冠状动脉主干血管成形术

目的介绍单一性左冠状动脉主干狭窄的外科手术方法.方法回顾性总结采用血管补片成形术治疗单一性左冠状动脉主干病变的手术结果.结果本组8例患者均存活,无围手术期心肌梗死等严重并发症发生,平均随访时间5年4个月;其中1例患者于术后6个月因心绞痛复发而行冠状动脉旁路移植术,术后无并发症发生;其余患者心绞痛症状均完全消失,并参与正常活动.结论冠状动脉主干血管成形术可作为单一性左冠状动脉主干狭窄的外科手术方式之一,但不宜用于病变血管处有管壁严重钙化的患者.

Left Main Coronary Artery Patch Angioplasty

Objective To introduce the technique of surgical patch angioplasty for the treatment of patients with isolated left main coronary artery stenosis.Methods Retrospective investigation of results of surgical patch angioplasty in patients with isolated left main coronary artery disease.Results All 8 patients who underwent left main coronary artery patch angioplasty survived with no major perioperative complications.One patient had recurrent angina and required coronary artery bypass grafting 6 months after patch angioplasty.All other patients were symptom free and had normal activity,at a mean follow-up of 5.3 years.Conclusions Patch angioplasty can be used as an alternative surgical technique in cases of isolated left main coronary artery stenosis with no distal coronary artery disease.However,it may not be suitable for patients with significant left main coronary artery calcification.
