Thromboembolism in the right tibial–peroneal artery during endovascular recanalization (EVR) in a 78-year-old man with severe claudication since 4 months and an 11-year history of diabetes.
Contrast-enhanced magnetic resonance angiography (CE-MRA) and digital subtraction angiography (DSA) images show occlusion in the right superficial femoral artery (SFA) and severe stenosis in the distal popliteal artery (PA) (A, B) (arrows). After balloon dilatation and stent placement in SFA, patency is achieved (C, D) (arrows). Thromboembolic complications are detected in the tibial–peroneal artery after balloon dilatation in distal PA (E, F and G) (arrows); therefore, percutaneous aspiration thrombectomy (PAT) is performed using a 5-French aspiration catheter. The embolus is suctioned out (H). DSA demonstrates a patent artery artery (I). Lower limb computed tomography angiography (CTA) images obtained 12 months after recanalization show patency of the right SFA and infrapopliteal arteries (J).

Thromboembolism in the left superficial femoral artery (SFA) in a 78-year-old man with severe claudication since 3 weeks.
Long-segment occlusion is detected in the left SFA using contrast-enhanced magnetic resonance angiography (CE-MRA) and digital subtraction angiography (DSA) (A, B) (arrows), and severe thromboembolism after stent placement is observed in SFA (C) (arrows). Percutaneous aspiration thrombectomy (PAT) is performed and embolic material is suctioned out (D). Final angiograms show good SFA patency (E).
