Critical Limb Ischemia Due to Aorto Iliac and Infrainguinal Artery Disease: Does Extensive Revascularization Warrant Limb Salvage?

Critical limb-threatening ischemia (CLTI) can be due to extensive involvement of the aorto-iliac and infrainguinal arteries. Both districts can be revascularized simultaneously to allow flow restoration in the limb; however, revascularization confined to the aorto-iliac (AI) district can be an alternative approach, to reduce operation time and invasiveness. The aim of the present study was to evaluate the limb salvage in patients with CLTI with both AI and infrainguinal peripheral artery disease (PAD) after revascularization confined to the AI district or extended also to the infrainguinal segment.
