Literature review highlights scarce evidence for retrograde revascularization of below-the-knee arteries in diabetic patients, indicating a need for dedicated clinical evaluation.
Chronic limb-threatening ischemia is the end stage of peripheral arterial disease. The revascularization of patients suffering from diabetes mellitus who present chronic total occlusions of below-the-knee vessels can be technically very difficult and sometimes impossible to achieve by performing only an antegrade approach. As regards retrograde recanalization, several studies have investigated the efficacy and safety of this technique in the femoropopliteal axis or in the infrageniculate arterial vessels in patients with advanced atherosclerotic disease. Currently in the literature there are still few studies analyzing the effectiveness of the retrograde approach in the treatment of occlusions of below-the-knee vessels in patients suffering from diabetes mellitus.
