Peripheral Arterial Occlusive Disease is associated with a high risk of cardiovascular events. The critical ischemia stage represents the most severe stage of Peripheral Arterial Occlusive Disease, associated with decubitus pain and / or foot ulceration. The severity of this arterial involvement involves functional prognosis of the lower limb with a high risk of amputation, and the vital prognosis of the patient. In these patients, the rate of amputation and mortality at 1 year can reach 20%. Therefore, the goal of management in a multidisciplinary setting is limb salvage and improvement of the patient's vital prognosis.

In the vascular medicine department, the indication and modalities of the revascularization procedure are discussed in a multidisciplinary consultation meeting. Surgical revascularization by distal bypass requires venous material that can be used, a receiving artery without diffuse lesions, in direct continuity with the arterial network of the foot, and the absence of co-morbidities against general anesthesia. With the modernization and development of endovascular equipment dedicated to the hamstrings, the interventional radiology techniques in the management of critical ischemia allow the treatment of one or more arterial axes as well as a very distal revascularization in the arteries. of the foot with less morbidity-mortality compared to surgery, especially in patients the most fragile patients. Since 2013, the endovascular revascularization procedures performed by the interventional radiology team have been an integral part of the management of patients with peripheral arterial disease of the lower limbs monitored in the vascular medicine department. The hospital is therefore a privileged place to observe the long-term impact of this medical care on the future of patients with different stages of severity of arterial disease.

The objective of this retrospective study is to evaluate the life-threatening, limb salvage and associated prognostic factors in patients with Peripheral Arterial Occlusive Disease supported by endovascular revascularization in the vascular medicine department of the GHPSJ.
