The foot was cool to touch. Sensory exam revealed diminished light touch sensation in the left foot and motor exam revealed mild weakness in the left foot. He was then transferred to the University of Cincinnati Vascular Surgery Service. Based upon the physical exam findings of a small right popliteal artery aneurysm an arterial duplex exam of the affected left lower extremity was performed which confirmed a thrombosed 2.8 cm popliteal artery aneurysm. B-mode ultrasound image of thrombosed left popliteal artery aneurysm.
Intraluminal thrombus is seen in the aneurysm.
No flow was detected with color duplex imaging. No tibial arterial runoff could be identified by color duplex ultrasonography of the left leg. Standard continuous doppler waveform analysis and segmental pressures revealed monophasic left popliteal artery waveforms with aphasic tibial flow. The right ABI was .70 and the left ABI was 0.
