Concomitant bilateral popliteal arterial aneurysm and abdominal aortic aneurysm in a case with severe occlusive disease of lower extremity

Results Color Doppler ultrasound revealed bilateral popliteal arterial aneurysm of 2-2.5 cm. Computed tomographic angiography showed a fusiform aneurysmal dilation of the abdominal aorta with a largest diameter of 38 mm. Left superficial femoral artery was totally occluded and the graft was patent. There was a high-grade stenosis at the site of proximal anastomosis. Both popliteal arteries showed aneurysmal dilation of 35 and 25 mm, right and left sides, respectively. Right peroneal artery was patent but the remaining two branches were perfused via collaterals. All of the 3 infragenual branches were patent on left with occlusion of the anterior tibial artery distally. Pedal arteries were patent. Coronary angiogram discovered some non-significant stenotic lesions at left anterior descending and right coronary arteries. With these findings, we planned percutaneous balloon dilation or, if necessary, stenting of the proximal anastomosis site and endovascular stent grafting of both popliteal arteries. He preferred to remain in outpatient follow-up.
