title: Subintimal arterial flossing with antegrade-retrograde intervention (SAFARI) and rertograde access for critical limb ischemia.
abstract: Retrograde access techniques involve the addition of a retrograde access into the distal target vessel to aid in recanalization of chronic total occlusions. Many patients with critical limb ischemia are also poor surgical candidates because of comorbidities or lack of suitable landing zone for bypass procedures. This approach may be helpful in the setting of chronic occlusions that cannot be crossed via conventional antegrade true-lumen approaches. Subintimal arterial flossing with antegrade-retrograde intervention technique can be used when the occlusion was crossed in the subintimal plane and antegrade re-entry techniques failed. It may also be useful for flush superficial femoral artery occlusions or those lesions that extend into the trifurcation vessels. Proficiency in these techniques allows limb salvage in patients who lack surgical options and would otherwise undergo amputation.
