Foot drop is a common and distressing problem that can lead to falls and injury. Clinical examination and laboratory data were not helpful for diagnosis. Chronic compression, histologic changes, and predisposing factors, such as vigorous exercise or hypercoagulability, play a role in these cases. Popliteal artery entrapment syndrome (PAES) occurs when muscles that surround the popliteal artery in the area of the popliteal fossa, occlude the artery (and sometimes the vein as well), and decrease blood flow to the lower leg. Conclusions: While popliteal entrapment remains a challenging diagnosis, the incorporation of functional imaging and application of an algorithm to resolve diagnostic discrepancies may be of benefit in improving the sensitivity of clinical evaluation. The anterior suprapatellar fat pad is enlarged with mass effect on the adjacent suprapatellar recess and quadriceps tendon 1-3. Popliteal artery entrapment syndrome (PAES) is an uncommon condition in which an abnormally positioned or enlarged calf muscle presses on the main artery behind the knee (popliteal artery). The artery becomes trapped, making it harder for blood to flow to the lower leg and foot. Ultrasound. The popliteal artery is interrogated from above the knee joint to bifurcation, using a linear 12 MHz or 9 MHz vascular transducer. The artery is imaged with the leg in the neutral position to assess for intimal changes, stenosis or aneurysm with B mode imaging as well as velocity and waveform criteria.
