ABSTRACT
Objective: To generalize the application and prospect of computed tomographic angiography (CTA) in deep inferior epigastric artery perforator (DIEP) flap transfer for breast reconstruction. Methods: The related literature using CTA for DIEP flap reconstruction of breast in recent years was reviewed and analyzed. Results: Preoperative CTA can accurately assess the vascular anatomy of the chest and abdomen wall, precisely locating the perforator in the abdominal donor site, and identifying the dominant perforator; guide the selection of intercostal space to explore internal mammary artery and internal mammary artery perforator in the chest recipient vessels. It can also reconstruct the volume of the abdominal flap with reference to the size of the contralateral breast and pre-shape the abdominal flap, which are crucial to formulate the surgical plan and improve the reliability of flap. Conclusion: Preoperative CTA has enormous application potential and prospects in locating donor area perforator, in selecting recipient vessels, and in evaluating breast volume for autologous breast reconstruction with DIEP flap.
