Ischemic prevention for stent implantation via brachial artery in children

An 11-year-old boy received stent implantation for peripheral pulmonary stenosis through the left modified Blalock-Taussig shunt from the left brachial approach because of the hairpin-shaped route from a femoral or carotid approach. A temporary bypass between the left radial and the femoral arteries was established to prevent ischemic complication of the left forearm. There was no ischemic change of the left forearm in the physiological monitoring despite the long procedure (more than 4 hr) and brachial arterial spasms. No complications occurred after the procedure. The temporary bypass will support fewer complications in various catheter interventions through a brachial arterial approach in children.
