A Path to Avoid during Transcatheter Aortic Valve Implantation: Case Report.
Collateral pathways in vascular disease are important natural "bypass" conduits that protect against ischemia. Endovascular diagnostic and therapeutic procedures via peripheral access sites are performed frequently. This case report underlines the importance of being aware of collateral circulation in patients with chronic aortoiliac occlusive disease undergoing subclavian transcatheter aortic valve implantation to avoid acute limb ischemia.
