Upper extremity peripheral artery aneurysms are rare, and have been previously reported in children to be associated with congenital malformations and infectious or inflammatory processes. In this case series, we present two unique cases of spontaneous isolated true aneurysms of the brachial artery in two children. Both cases were incidentally found on examination, diagnosed by ultrasonography, and successfully managed by surgical excision and micro-vascular repair with vein grafting. Highlights ? Isolated spontaneous true brachial artery aneurysm in children is rare. ? Diagnosis is often incidental, and verified by multimodal imaging techniques. ? Treatment involves surgical excision with reconstruction. ? Often involves transposed vein grafts, namely reversed saphenous or basilic veins. ? Micro-vascular repair technique is safe and feasible in select patients.
