Abstract:
The perforator flap is one of the most useful techniques in reconstructive surgery. The operative procedure for these flaps will be greatly simplified if accurate localization of the course of the perforator can be preoperatively confirmed. However, small vessels with diameters less than 0.5 mm cannot be readily traced with conventional imaging techniques. Local skin warming temporarily increases cutaneous blood flow and vasodilation. In this study, we established a local skin warming procedure, and performed this before color duplex imaging to improve preoperative perforator mapping and enable precise flap design.
