To assess the impact of an assistant on the technical skills of the operator performing superficial femoral artery (SFA) angioplasty on the vascular intervention simulation trainer (VIST) simulator.
Eight experts performed 2 SFA angioplasties each on the VIST. Four experts had an assistant available. Experts' video recordings were blindly evaluated using global and procedural rating scales.
Experts with assistants scored higher than the controls in the first: global rating scale (47.8 ± 0.5 vs 33.5 ± 5.1, P = .01); procedural rating scale (94.3 ± 2.2 vs 89 ± 2.5, P = .02) and the second procedure: global rating scale (47.8 ± 0.5 vs 38 ± 7, P = .03); procedural rating scale (95.3 ± 0.5 vs 89.5 ± 2.4, P = .02).
The presence of an assistant had a positive influence on the technical skills of the operator performing SFA angioplasty on the VIST simulator.
评估在血管介入模拟训练器（VIST）模拟器上，助手对进行股浅动脉（SFA）血管成形术的操作者技术技能的影响。
八位专家在VIST上各进行2次SFA血管成形术。四位专家有助手协助。使用整体评分量表和操作评分量表对专家的视频记录进行盲法评估。
有助手的专家在第一次操作中：整体评分量表得分（47.8±0.5对33.5±5.1，P = 0.01）；操作评分量表得分（94.3±2.2对89±2.5，P = 0.02）；在第二次操作中：整体评分量表得分（47.8±0.5对38±7，P = 0.03）；操作评分量表得分（95.3±0.5对89.5±2.4，P = 0.02）均高于对照组。
在VIST模拟器上，助手的存在对进行SFA血管成形术的操作者的技术技能有积极影响。
