[en] The lower extremity arterial vasculature encompasses a balanced, tapering distribution closely related to
the muscular compartments of the leg and foot. From the main ilio-femoral inflow to further remote capillary vessels, a
harmonious pyramid of gradually tapering limb perfusion is created. This impressive vascular system is structured into
several ranks of tapering vessels that correspond with angiosomes in the lower extremities. Each of these levels expresses
unique anatomic features when threatened by atherosclerotic ischemic disease. As atherosclerosis progressively worsens,
the vascular anatomy, including the tibio-pedal trunks, foot arches, and collateral distributions, continuously provides
coordinated support and dynamic adaptations in regional perfusion of the foot, in accordance with various endogenous
and exogenous factors. Critical limb ischemia (CLI) involves characteristic infragenicular patterns of arterial disease and
related compensatory flow paths that are useful for interventionists to acknowledge and understand. The present article
briefly reviews the main anatomical features describing infra-popliteal arterial vasculature with, and without, ischemic
impairment, in accordance with practical clinical issues encountered in daily practice.
