Variant anatomy is relatively common in the lower extremity arteries and can play
a role both in the incidence of peripheral arterial disease and the interventions
performed to treat such disorders. Recognition of such anatomic variants prior to
performing interventions on these patients is vital to be able to appropriately plan
arterial approaches and in determining what intervention may be most appropriate for
such patients. Interventional radiologists who perform lower extremity arterial interventions
should be familiar with the most common anomalies affecting these vessels; this article
discusses common lower extremity arterial anomalies and how these anomalies can affect
interventional procedures in these vascular distributions.
