Spontaneous isolated true aneurysms of the brachial artery in children

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.
