Purpose: Since the first report of TRAM flap reconstruction, there have been numerous studies to reduce complications of elective breast reconstruction. Current methods of preoperative perforator localization can be time-consuming, inaccurate, and imprecise. Thus, we sought to evaluate ultra-high resolution 3D CT angiography for the preoperative mapping of DIEAP flap perforating vessels. Methods: We reviewed all perforator-based breast reconstructions performed over a 5-month period. Candidates for DIEAP flap reconstruction were sent for a focused CT scan of the abdominal wall, using the 64 slice multi-detector CT scanner. Results: This article presents our first 23 flaps in 17 patients with preoperative ultra-high resolution 3D CT angiography. The reconstruction plan changed in three patients (18%). There was one take-back for venous congestion, but no partial or total flap loss. Conclusions: Preoperative perforator flap planning for breast reconstruction utilizing 3D CT angiogram is safe, easy to read, and can change the operative plan.
