Dynamic anatomical study of the posterior brachial artery perforator flap: Aesthetic refinement and clinical results

Reconstruction of the axillary fossa represents a surgical challenge given the functional implications for mobility of the upper limb. The posterior brachial flap is a solution of choice for this indication, providing fine and functional local reconstruction, but little is known about its perforasome. This study aimed to identify the location of the perforator, analyze perfusion flow, and link vessel distribution, and propose an aesthetic refinement to the surgical technique by medializing the skin paddle to conceal aesthetic scarring at the donor site.
