SCAI expert consensus statement for aorto-iliac arterial intervention appropriate use.

Aorto-iliac arterial occlusive disease is common and may cause a spectrum of chronic symptoms from intermittent claudication to critical limb ischemia. Treatment is indicated for symptoms that have failed lifestyle and medical therapies or occasionally to facilitate other interventional procedures such as TAVR and/or placement of hemodynamic assist devices. It is widely accepted that TASC A, B, and C lesions are best managed with endovascular intervention. In experienced hands, most TASC D lesions may be treated by endovascular methods, and with the development of chronic total occlusion devices, many aorto-iliac occlusions may be recanalized safely by endovascular means. Interventional cardiologists should be well versed in the anatomy, as well as the treatment of aorto-iliac disease, given their need to traverse these vessels during transfemoral procedures. Overall, aorto-iliac occlusive disease is more commonly being treated with an endovascular-first approach, using open surgery as a secondary option. This document was developed to guide physicians in the clinical decision-making related to the contemporary application of endovascular intervention among patients with aorto-iliac arterial disease.
