perforator mapping
Preoperative imaging technique to identify and locate blood vessels for perforator flap harvest planning.
Full Definition
Perforator mapping is a preoperative imaging technique used to identify the location, size, and course of perforating blood vessels that will supply a perforator flap. This process typically employs computed tomographic angiography (CTA) or magnetic resonance angiography (MRA) to visualize the vascular anatomy. Accurate perforator mapping is crucial for successful flap harvest as it allows surgeons to select the best perforators and plan the optimal flap design. The technique has significantly improved outcomes in microsurgical breast reconstruction by reducing operative time and flap complications.
