Bilateral Axillary Artery Aneurysms in a Six-Year-Old Child

True axillary artery aneurysms in children are rare and mostly caused by blunt trauma. Idiopathic bilateral axillary aneurysms in children are even more infrequent, and evidence for optimal management is scarce. Moreover, the maximum follow-up time of interventions reported in pediatric axillary artery aneurysms was less than 1 year, and long-term outcomes remained unknown. In this report, we presented a 6-year-old child with bilateral axillary artery aneurysms treated by saphenous vein reconstruction with a 5-year follow-up. Meanwhile, we reviewed the etiology and treatment of true axillary artery aneurysm in children, which we hope would add information to the scarce evidence of management of true axillary artery aneurysms in children.
