【摘要】：目的探讨完全经皮主动脉腔内修复术(percutaneous endovascular aortic repair,PEVAR)的学习曲线。方法回顾性分析2012年12月~2015年8月我科同一主治医师完成的40例PEVAR的临床资料,按手术时间顺序分为4组(G1~G4组),每组10例,对4组手术时间、技术成功率、并发症、出血量、缝合器数量进行比较。结果 G1组手术时间(19.9±4.3)min,显著长于G2组(16.4±3.9)min、G3组(10.4±2.1)min和G4组(10.3±1.5)min(q=3.484,P0.05;q=9.458,P0.05;q=9.557,P0.05),G2组手术时间明显长于G3组和G4组(q=5.973,P0.05;q=6.073,P0.05),G3组和G4组手术时间无统计学差异(q=0.100,P0.05)。G1、G2组技术成功率均为80%,与G3、G4组(均为100%)无统计学差异(χ~2=4.444,P=0.217)。4组在并发症、出血量和使用缝合器数量方面无统计学差异(P0.05)。结论 PEVAR存在学习曲线,20例后完成PEVAR学习曲线。
[Abstract]:Objective to study the learning curve of percutaneous endovascular aortic repairn PEVARA. Methods the clinical data of 40 cases of PEVAR completed by the same attending physician from December 2012 to August 2015 were retrospectively analyzed. The patients were divided into 4 groups according to the operation time, 10 cases in each group. The operative time, technical success rate, complications and bleeding volume were analyzed in 4 groups. The number of stitches was compared. Results the operative time of G1 group was 19.9 卤4.3 min, significantly longer than that of G2 group (16.4 卤3.9 min) and G3 group (10.4 卤2.1)min) and G4 group (10.3 卤1.5 min). The success rate of operation in G1 group was significantly longer than that in G3 group and G4 group (10.3 卤1.5min), and the success rate of operation in G4 group was not significantly longer than that in G3 group and G4 group (P 0.05q6.073 group and G4 group). The success rate of operation in G1 group was significantly longer than that in G3 group and G4 group (P 0.05 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05, P 0. 05). There was significant difference between the two groups (蠂 2 / 4.444 / P = 0.217.4). There was no significant difference in the amount of blood loss and the number of suture devices used (P 0.05). Conclusion the learning curve of PEVAR was found in 20 cases, and the learning curve of PEVAR was completed in 20 cases.
