Current state of the art in perforator flap imaging with computed tomographic angiography

Abstract

Computed tomographic angiography (CTA) has become increasingly adopted for preoperative imaging in perforator flap surgery, as it has been shown to improve operative outcomes and decrease operating times prior to deep inferior epigastric artery perforator (DIEP) flap and anterolateral thigh perforator flap surgery. Current technologies are readily available for the preoperative imaging of all perforator flaps, however only sporadic reports of the use of CTA for the imaging of other perforators have been described. We describe our experience with 325 CTAs performed for the preoperative imaging of perforators prior to 370 perforator flaps throughout several body regions. The scanning technique..
