Chetham-platinum-covered stent, aortic coarctation, and left subclavian artery: sometimes is there one too many?

A new approach was used in the percutaneous treatment of two patients with severe recoarctation involving the origin of the left subclavian artery. A tiny handmade fenestration was created in a NuMED-covered Cheatham-platinum stent before its implantation to avoid left subclavian artery occlusion. The stent placement was performed using a two-guidewire technique in which the different stiffness helped a proper positioning of the stent. After the stent deployment, the fenestration was enlarged performing a balloon angioplasty to improve flow in left subclavian artery.
