title: Awareness of anatomical variations for infrapopliteral intervention.
abstract: With the tremendous advancement and accumulated expertise of endovascular techniques, infrapopliteal intervention is emerging as an alternative therapeutic option to distal bypass surgery for limb salvage in the setting of critical limb ischemia (CLI). However, though much attention has been given to infrapopliteal intervention, the importance of identifying preprocedural infrapopliteal variants remains underappreciated. Becoming more aware of these anatomical variants will translate to increased clinical effectiveness for the patient with infrapopliteal artery disease. Therefore, this review will highlight the fundamental aspects of infrapopliteal variant anatomy for the catheter-based treatment of CLI patients with symptomatic infrapopliteal artery disease.
