颈动脉内膜切除术在单中心不同经验阶段的安全性分析

Safety analysis of different experience stage with carotid endarterectomy in a single center

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 effect of the different experience stage of carotid endarterectomy （CEA） on surgical safety. Methods Clinical data of 441 patients receiving CEA were analyzed retrospectively. According to the time, the patients were divided into initial experience group （n = 57） and recent experience group （n =384）. The stroke and mortality rate was compared in the two groups. Results The stroke and mortality rate was 12.3% and 2.9% for initial experience group and recent experience group respectively. There was significant difference in mortality and stroke rate between the two groups after the operation （P = 0.003）. Conclusions The stroke and mortality rate of the patients will decrease with the increase of surgical procedures and accumulation of surgical experience.
