There were no radiological features of infection in the surrounding tissues (Fig. 2).
(A) Preintervention angiogram demonstrating the pseudoaneurysm of the anterior tibial artery (ATA- Red Arrow) below a high take-off posterior tibial artery (PTA). (B) Post intervention angiogram confirming adequate stent placement (red arrow) with exclusion of the ATA pseudoaneurysm using a covered stent.

ANL1 sheath (Cook, Bloomington, IL, USA) that was positioned over the aortic bifurcation into the superficial femoral artery. An angiogram demonstrated the ATA pseudoaneurysm and confirmed distal runoff via three vessels (Fig. 3A). An ePTFE 3.5 x 26 mm Graftmaster RX covered stent (Abbott Vascular Devices, Abbott Park, IL, USA) was deployed across the pseudoaneurysm neck. Angiogram confirmed both the absence of flow in the pseudoaneurysm and preserved flow distally (Fig. 3B).
