[Preoperative angiographic CT-scan for perforator flap transfer. Clinical applications in an emergency unit of reconstructive surgery: four clinical cases].

Our experience of the deep inferior epigastric artery perforator flap has led us to perform systematically an abdominal CT-scan for the pretherapeutic checking. This exam gives us a precise vascular mapping of musculocutaneous and septocutaneous perforators artery of the flap, may enable a better orientation in the dissection and reduce the surgery time. We have enlarged the indication of this exam to the members flaps who needs the dissection of a musculocutaneous or a septocutaneous perforators vessels: Nakajima's et al. classification [1]. The mapping of perforating vessels on 3D reconstruction pictures helps us to planify the vascular cutaneous autologous grafts.
