The aim of this study is to evaluate the amount of training needed by a trainee, with no background in microsurgery, in order to achieve proper skills for microvascular anastomosis. A protocol based on the rat femoral artery was established to provide a quantitative representation. Five inexperienced subjects started performing microvascular anastomosis. Patency was assessed at 30 min. The final assessment was performed at 2 weeks when rats were reoperated and the patency below the anastomosis was checked. The experiment was discontinued for one subject when he/she succeeded to have two series of four anastomosis with 100% patency at 2 weeks. The results were: 47.5% patency rate at 30 min and 7.5% at 2 weeks (series 1–2); 67.5 and 32.5% (3–4); 82.5 and 35% (5–6); 100 and 70% (7–8); 100 and 87.5% (9–10). Two trainees obtained 100% patency at 2 weeks after series 9–10. Other three needed two more series. There is a significant statistic difference ( P < 0.01) between the results at 30 min and 2 weeks for the series (1–2, 3–4, 5–6, 7–8). The patency rate at 2 weeks reflects in a better way the microsurgical skills of a trainee. For long term functioning anastomosis, the training period needs an extension beyond that necessary for 100% patency at 30 min. © 2007 Wiley‐Liss, Inc. Microsurgery, 2007.
