case_images: Preoperative reconstructed computed tomography angiography of the tibial arteries bilaterally, demonstrating abrupt occlusion of the left posterior tibial artery and a right-sided posterior tibial artery aneurysm. Please note that artefact from bilateral knee prostheses obstructs visualising normal flow within the popliteal arteries in this image.

case_images: Dominant flow to the foot was via the PTA, which occluded in the distal calf (Figure 1).

case_images: A PTA thrombectomy was performed and subsequent angiography demonstrated flow to the foot via the aneurysmal PTA (Figure 2).

case_images: The aneurysm was opened and demonstrated a mixture of old, organised, and fresh thrombus (Figure 3).
case_images: Postoperative angiography demonstrating flow to the left foot through the interposition long saphenous vein graft.

case_images: PTA was repaired using an interposition long saphenous vein graft (Figure 4). Postoperatively, the PTA pulse was present, the foot had brisk capillary refill, and motor and sensory function normalised.
