The emergency duplex ultrasound and CT angiography demonstrated an eccentric fusiform aneurysm of the left P2 popliteal artery with a maximal diameter of 14 mm, complicated by distal embolic occlusion of all three runoff vessels (Figure 1).
Completion angiography after open thrombectomy: residual stenosis of the posterior tibial artery treated with balloon angioplasty.

Completion angiography demonstrated a residual stenosis of the posterior tibial artery, and a balloon angioplasty was performed resulting in a satisfactory runoff (Figure 2).
Flow diversion effect after stent implantation: flow stagnation between the aneurism wall and the stent, corresponding to the grade C2 of the O'Kelly-Marotta scale.

The deployment was uneventful, and the immediate flow diversion effect was encountered, with the presence of the flow stagnation between the aneurism wall and the stent, corresponding to grade C2 of the O'Kelly-Marotta flow diversion scale (Figure 3).
Follow-up CT angiography: complete exclusion of the aneurism and preserved patency of the posterior tibial artery.
