Femoro-popliteal segment is often characterized by diffuse and severe steno-obstructive atheroclerotic disease. Most recent guidelines recommended endovascular techniques as a valid and safe treatment in highly symptomatic patients (Rutherford class 4 to 6) with complex femoropopliteal lesions (TASC C and D). Continuous technical development is increasing the efficacy of the endovascular technique with the introduction of new dedicated devices. In most complex situation also retrograde recanalization can be applied. The main indication to this technique is when conventional antegrade recanalisation fails or cannot be apply. The most common retrograde access is through the popliteal artery. However many operators do not like this approach due to the technical issue correlated to the patient position. Recently several reports have been published keeping the patient supine improving patient comfort and operator activity. This tehnique was also affected by several complications at the level of the popliteal puncture site, but those were resolved with the improvement of technique and operator skills. Hence several Authors described different variants of such technique (subintimal techniques, patient in supine position, puncture of the distal superficial femoral artery, tibial/pedal artery access) all obtaining an high rate of success with a low complication rate. In conclusion retrograde recanalization can be considered a safe and effective technique for complex femoral lesions. It is also less expensive than recanalisation devices, less time consuming and can increase the outcome due to the higher percentage of intraluminal recanalization.
