Abstract： To the Editor:This is a brief clinical report on different endovascular procedures in the treatment of popliteal artery aneurysms (PAAs).A 75-year-old man presented at the vascular clinic with progressive left lower limb pain at rest associated with coolness,pain,and paresthesia.His medical history was significant for hypertension and hyperlipidemia.The femoral and popliteal pulsations were only felt in the left limb.Coldness,pallor,paresthesia,delayed capillary refilling,and color changes were noted in the left limb together with rest pain.Duplex ultrasound was performed and an embolization (Rutherford Grade 2b) and bilateral PAAs were found,which on computed tomography angiogram (CTA) measured 62 mm and 82 mm with the maximum diameters in the right and left popliteal artery,respectively.Thrombus was found in both aneurysm sacs [Figure 1 a and b].Thromboembolism from the left PAA could be seen in the distal arteries.Other potentially associated aneurysms were excluded by magnetic resonance angiography.The erythrocyte sedimentation rate and C-reactive protein were moderately elevated,and thrombophilia profile was negative,and history for any orogenital ulcers was negative.
