This research aims to identify and quantify technical nuances in microvascular anastomosis using a skill decomposition approach.
Four microneurosurgery trainees performed 16 end-to-side microanastomoses using interrupted and continuous suturing techniques.
24 reproducible suturing techniques and 42 technical insufficiencies were identified at the subtask level.
Performance metrics included duration of anastomosis and number of technical insufficiencies.
Continuous technique (CT) was 19% faster than interrupted technique (IT), with mean times of 15.7 min (CT) vs. 19.1 min (IT), p = 0.02.
IT resulted in 40% more technical insufficiencies per anastomosis compared to CT, mean 37 vs. 26.5, p = 0.04.
Biting both walls in a single move and dominant-hand suturing contributed significantly to faster suturing.
