Subintimal Arterial Flossing with Antegrade-Retrograde Intervention (SAFARI) for Subintimal Recanalization to Treat Chronic Critical Limb Ischemia

The SAFARI technique can be useful for completing subintimal recanalization when there is failure to reenter the distal true lumen from an antegrade approach or when there is limited distal target artery available for reentry. The SAFARI technique improves technical success in the performance of subintimal recanalization. Limb salvage rates are comparable to those with antegrade subintimal recanalization.
