ANDRADES C, Patricio et al. CT Angiography in preoperative identification of perforator vessels. Rev Chil Cir [online]. 2014, vol.66, n.2, pp.134-141. ISSN 0718-4026.  http://dx.doi.org/10.4067/S0718-40262014000200007.

Introduction: Perforator flaps have become a coverage option validated and increasingly used in reconstructive surgery. These flaps require preoperative identification and intraoperative dissection of the perforator vessels. The aim of this study was to evaluate the use of Angio CT in the preoperative assessment of perforating vessels and its correlation with intraoperative findings. Material and Methods: We retrospectively reviewed all perforator flaps performed at the Division of Plastic Surgery, University of Chile Clinical Hospital between June 2009 and June 2012. All patients were asked for an Angio CT according to the protocol of the University of Gent (Belgium). Data points were used and a specific coordinate system to locate the point at which the perforator vessel fenestrate the deep fascia. The information provided in the Angio CT was compared with surgical findings. Results: A total of 41 patients underwent perforator flap planning during the study period. 40 underwent surgery: 18 women and 22 men, with a mean age of 46.6 ± 5.7 years. Flaps were performed as follows: anterolateral thigh (ALT) = 14, inferior epigastric (DIEP) = 18, superior gluteal (SGAP) = 5, posterior tibial (PTAP) = 4 and thoracodorsal (TDAP) = 2. In all cases the Angio CT identified one or more perforator vessel with a 100% concordance with intraoperative findings. Conclusions: CT Angio is a test with high performance in preoperative characterization of perforator vessels. It is a helpful tool that must be considered whenever planning this type of flaps.
