Comparison of ligation security between monofilament polydioxanone and pseudomonofilament polyamide sutures in a standardized vascular model.

< 0.001). Leakage was eliminated only at 14 N for both materials, whereas high leakage rates occurred at lower force levels regardless of suture material. Time interval and suture material were not independently associated with leakage. These findings indicate that ligation security in this model is determined primarily by tying force rather than by filament configuration.
