To describe the spectrum of axillary artery pathology seen in high-performance overhead athletes and the outcomes of current treatment. ⋯ Repetitive positional compression of the axillary artery can cause a spectrum of pathology in the overhead athlete, including focal intimal hyperplasia, aneurysm formation, segmental dissection, and branch vessel aneurysms. Prompt recognition of these rare lesions is crucial given their propensity toward thrombosis and distal embolism, with positional arteriography necessary for diagnosis. Full functional recovery can usually be anticipated within several months of surgical treatment, consisting of mobilization and segmental reconstruction of the diseased axillary artery or ligation/excision of branch aneurysms, as well as concomitant management of distal thromboembolism.
