title: Imaging Studies for Preoperative Planning of Perforator Flaps: An Overview.
abstract: The vascular anatomy of perforators varies between individuals; thus, accurate preoperative assessment of perforators is essential for safely planning perforator flaps. Perforator computed tomographic angiography (P-CTA) with multidetector-row computed tomography (MDCT) is one of the best available methods to precisely reveal the 3-dimensional anatomic details of perforators. The aim of this report is to describe the authors' experience using P-CTA with MDCT for detecting the perforating vessel preoperatively and a step-by-step approach to harvest perforator flaps based on this technique. This report also provides a comprehensive review of literature on other preoperative assessment tools of perforators.
