Femoral artery thrombosis

Case contributed by Dr Varun Babu

Presentation

Known case of peripheral vascular occlusive disease.

Patient Data

Age: 80 years
Gender: Male
Ultrasound

Diffuse calcification of all the lower limb arterial tree. Spectral broadening with biphasic pattern in the common femoral artery. Complete occlusion of the proximal 2/3 of superficial femoral artery.

Distal third reformed weakly by deep femoral artery collaterals.

Monophasic low velocity flow seen in the popliteal and all infrapopliteal vessels.

Case Discussion

This case demonstrates a long segment thrombotic occlusion of the proximal 2/3 of the superficial femoral artery. Deep femoral arterial collaterals always tend to reform at the terminal third of femoral artery. The alteration in pattern to monophasic flow confirms a significant proximal occlusion.
