[Post Traumatic Pseudoaneurysm of the Axillary Artery with Late Clinical Presentation]. / Pseudoaneurisma Pós-Traumático da Artéria Axilar com Apresentação Clínica Tardia.

Traumatic lesions of the axillary artery are rare in fractures of the proximal humerus. Clinical manifestations are sparse, generally presenting in the acute form, although in some cases the clinical signs only emerge later after the traumatic event. The early diagnosis might prevent serious complications. The authors present a case of a traumatic lesion of the axillary artery, with a delayed presentation, resulting from a traumatic fracture of the proximal third of the humerus that required emergent surgical management.
