目的分析比较颈动脉内膜切除术(CEA)不同经验阶段对手术安全性的影响。方法回顾性分析441例接受CEA治疗的颈动脉狭窄病人的临床资料,依照时间分为初期经验组(57例)和近期经验组(384例),对比两组在卒中和病死率等方面的差异。结果初期经验组和近期经验组术后卒中和病死率分别为12.3%和2.9%,差异存在统计学意义(P=0.003)。结论随着手术量不断增加,手术经验不断积累,CEA术后的卒中和病死率也会不断下降。
Objective To analyze the influence of different experience stages of carotid endarterectomy (CEA) on the safety of surgery. Methods The clinical data of 441 patients with carotid artery stenosis treated with CEA were retrospectively analyzed. They were divided into initial experience group (57 cases) and recent experience group (384 cases) according to time. The difference of stroke and fatality rate between the two groups was compared . Results The postoperative stroke and fatality rate in the initial experience group and the recent experience group were 12.3% and 2.9%, respectively, with statistical significance (P = 0.003). Conclusion With the continuous increase of operation and the accumulation of surgical experience, the stroke and case fatality rate after CEA surgery will continue to decline.
