An arterial duplex exam is ordered on a 55 y/o patient experiencing claudication in the thigh and calf. The following velocities were obtained at the mid SFA. Classify the percent diameter reduction.  Pre-stenotic PSV: 80 cm/sec PSV within the stenosis: 280 cm/sec

The following bilateral brachial and high thigh pressures were documented in a LE segmental pressure exam:   RT Brachial: 144 mmHg                       LT Brachial: 140 mmHg RT High thigh: 110 mmHg                    LT High thigh: 177   These findings could result from all except:

What is the most likely complication of a peripheral artery aneurysm?

What is the significance of retrograde flow in the native vessel at the distal anastomosis of an in situ vein graft?

EXTRA credit: Perigraft fluid is identified on ultrasound when infection is present around the graft. 

What absolute toe pressure indicates poor chance of foot ulcers’ healing?

Which of the following most accurately describes vascular claudication?

With which type of bypass graft will there be a size discrepancy between the graft and the native artery at both the proximal and distal anastomotic sites?

Where does the peroneal artery originate?

ABI ratio associated with claudication:
