摘要
目的 :探讨无保护左主干病变患者冠状动脉 (冠脉 )内支架术的近、远期疗效。方法 :共选择 8例均无冠脉搭桥术史的左主干病变患者行冠脉内支架术 ,其中左主干近中段病变 5例 ,远段分叉病变 3例 ,其中 2例的左室射血分数 <4 0 % ,总结分析其临床、左主干病变特点、手术成功率及随访结果。结果 :左主干支架术的成功率为 10 0 % ,无残余狭窄或残余狭窄率 <10 % ,无任何严重并发症如支架内血栓形成、急性心肌梗死、紧急外科冠脉搭桥术或死亡等。术后随访 5～ 15 (10± 3.5 )个月 ,无一例死亡。临床心绞痛复发 1例 ,重复冠脉造影证明为前降支的新生病变所致 ;2例左室功能不全患者的左室射血分数提高了 15 %以上 ;5例复查了冠脉造影 ,其中 4例的原支架内基本无再狭窄 ;1例有 30 %再狭窄 (为前述症状复发的患者 )。结论 :支架置入术治疗无保护左主干病变疗效显著 ,是值得考虑的治疗手段 ;
Objective:To evaluate the initial and follow-up results of elective coronary artery stenting on unprotected left main coronary artery disease.Method:Eight patients with unprotected left main coronary artery disease had been treated with stenting, of which 5 with proximal lesion, 3 with distal bifurcateion lesion. 2 patients with EF less than 40% were found in our group. Clinical characteristics, angiographic results, successs rate, severe complications and follow-up results were analyzed respectively. Result: The successs rate of the procedure was 100%, without remained stenosis and cardiac complications. Average follow-up was (10± 3.5) months, none of death. One patient had recurrent angina because of a new lesion of left anterior descending branch. The EF of the 2 cases with left ventricular dysfunction increased more than 15%. Repeat CAG was obtained in 5 patients and showed that only 1 patient was found in-stent restenosis of 30%. Conclusion: Elective coronary artery stenting is effective and considerable for treatment of unprotected left main coronary artery disease. Suitable case selection and operative skills are the keys of the procedural successs.
