[Post-traumatic aneurysm of humeral artery].

Aneurysms are uncommon in the pediatric age-group. Unlike adults, in which aneurysms appear after alteration of the arterial wall due to systemic diseases, in children the traumatic etiology has to be considered: blunt trauma may disrupt the arterial wall and cause false aneurysm (pseudoaneurysm). Most aneurysms are asymptomatic, or they present as a pulsatile mass on an arterial traject. Diagnosis is confirmed with Doppler ultrasound and angiography. We present the case of a girl who, after blunt trauma of the right upper limb developed a pulsatile mass on the traject of the right humeral artery. Doppler ultrasound and angiography confirmed aneurysm of the humeral artery. She was successfully treated with surgical resection of the aneurysm and reconstruction of the arterial wall.
