Critical limb ischaemia is the end stage of peripheral arterial disease before limb loss. Contemporary interventions to restore blood flow have high morbidity and mortality and fail to provide sustained restoration of peripheral circulation. Cell-based therapies designed to promote neovascularisation or angiogenesis have been shown in trials to be safe but clinically ineffective. Notwithstanding endless research in the area, no headway has been made in identifying a successful therapy designed specifically to target muscle disease in critical lower limb ischaemia. Thus, the quest to find an effective, lasting solution for critical lower limb ischaemia continues and requires more innovative therapeutic tactics. Our aim is to highlight the crucially interlinked role of the capillary bed, skeletal muscle mass and mitochondria in critical lower limb ischaemia patients and to identify novel therapeutic mechanisms that the vascular interventionalist can add to their armamentarium.
