Abstract PS2-05-05: The Anatomic Basis of Thoracodorsal Artery Perforator-based Flap: Cadaveric and Angiographic Study

Abstract Introduction: Breast cancer surgery has shifted towards breast conservation surgery. Perforator-based flaps play a pivotal role. The thoracodorsal artery perforator-based (TDAP) flap is one such. In TDAP, varied amount of skin and subcutaneous fat can be used. It can reach any quadrant of the breast. It can even be converted to a musculocutaneous flap, if a larger volume is required. In this study, the anatomical and vascular basis of TDAP were analysed using computed tomography angiographic (CTA) and cadaveric dissection (CD). Methods: A prospective observation study was carried out over 2 years in AIIMS, New Delhi. TDAP was dissected in 10 cadavers (20 sides). As part of metastatic workup, CTA was done in 23 locally advanced breast cancer (LABC) patients along with bone scan. Fresh, Theil cadavers, cadavers ≥ 18 years of age, and female BC patients >18 years were included. Injury/ scarring of chest wall, previous axillary surgery and cadavers/ patients
