Abstract
Currently, there are more opportunities to treat patients complicated with critical limb ischemia (CLI), which is a very dismal medical condition associated with a high risk of major amputation, disability and death. Because CLI is usually caused by multi-level occlusive atherosclerotic disease, the condition of CLI induced by aorto-iliac occlusive disease (AIOD) alone is thought to be a rare pathological entity. We encountered a patient with severe CLI caused by solitary AIOD. Three vascular access routes were established and stiff guidewires retrogradely passed the occluded arteries on both sides. We deployed two self-expandable bare metal stents and complete revascularization led to wound healing. Recent improvements of catheter devices and procedural techniques related to endovascular treatment (EVT) have enabled us to safely recanalize complex vascular lesions of the lower extremities. Therefore, an EVT strategy is one of the favorable treatment options for CLI patients who are contraindicated for surgical treatments.
