Trauma to the wall of an artery may lead to the development of a pseudoaneurysm. There are infrequent case reports of children who have developed pseudoaneurysms after vascular access attempts. The options for management are limited in children and even more so in neonates. We describe the presentation and management of a 6-week-old infant who had attempts at insertion of an intravenous catheter as a newborn. She presented with an enlarging mass of the right upper extremity with no palpable radial pulse on examination. Workup included radiographs, Doppler ultrasound, and magnetic resonance imaging that established the diagnosis of pseudoaneurysm of the brachial artery. She underwent a repair of the right brachial artery by identifying the site of the arterial injury and oversewing the defect in the wall. Intraoperatively, she had good arterial flow with a return of the radial pulse. The patient did well immediately postoperatively and has been followed for more than a year with normal pulses and growth of the upper extremity. Patients that have had previous attempts at vascular access and subsequently develop a mass in the area of puncture should be worked up for the potential of a pseudoaneurysm. Doppler ultrasound and magnetic resonance imaging may help with diagnosis. Primary repair is advocated in this injury to ensure adequate growth of the limb.
