Ligation with patch angioplasty of the axillary artery for circumflex humeral artery aneurysms.

Circumflex humeral artery aneurysms are rare vascular injuries that can lead to disastrous consequences if there is a delay or error in diagnosis. Previously only described in young elite athletes, this case series of eight patients, including a symptomatic 59-year-old man, illustrates the need for its inclusion in the differential in isolated arm ischemia regardless of age. Ligation without revascularization is the most commonly reported intervention; however, this does not address the axillary artery inflammatory thickening associated with the development of these aneurysms. We propose that aneurysm ligation with patch angioplasty of the axillary artery enables treatment of all arteries affected in the quadrilateral space.
