Endovascular treatment strategies for supra-aortic arterial occlusive disease

Because of the focal nature of stenoses or occlusions in the supra-aortic vasculature, the high blood-pressures in this area and the very low morbidity rates related to percutaneous therapy have largely replaced surgical revascularization as the initial treatment of choice for patients with supra-aortic arterial occlusive disease. The initial technical success and durability of percutaneous angioplasty (PTA) and stenting in these lesions is excellent. Nevertheless several factors can make PTA and stenting a complex procedure that requires advanced endovascular skills for a successful outcome. Profound knowledge of surgical reconstruction techniques or extra-anatomic bypasses remains mandatory, as it is occasionally required for failure of endovascular techniques or if contraindications exist.
