a and b Images from a percutaneous angiogram of the left lower limb. a Anteroposterior digitally subtracted imaging of the leg distal to the popliteal artery demonstrating a single below-knee dominant vessel (PAM), with a small branch as continuation of the usual course of the peroneal artery (arrow) and site of subsequent end-to-side microanastomosis to the PAM (arrowhead). b Lateral image of the left ankle showing the PAM passing posterior to the medial malleolus and into the plantar arch, with retrograde flow into the dorsalis pedis artery, but no apparent contrast in the region of the anterior tibial artery. An external fixator is present
