Popliteal artery entrapment syndrome has been reported to be a rare disease typically found in athletic and otherwise healthy young adults. It manifests as a temporary lower limb pain that occurs in connection with physical exercise. It is caused by an anatomic anomaly, usually anaberrant head of the gastrocnemius muscle that compresses the popliteal artery on the backside of the knee joint. The popliteal artery is the main vessel supplying blood to the lower part of the leg and the condition, if left untreated, can lead to serious complications such as thrombosis or aneurysm. If detected in time and surgically corrected patients can expect full recovery within weeks.The purpose of this study was to examine a group of healthy asymptomatic individuals (n=50)using ultrasound and a series of provocation to see if there was a possibility of entrapment. A secondary objective was to find which maneuvers during the ultrasound would provide the best results. They were subjected to ultrasound examinations at rest, during plantar flexion without resistance, against a light resistance and against substantial resistance.The results showed that most of the test subjects could temporarily constrict blood flow greatly although ultrasound imagery alone was not enough to confirm diagnosis. It seems that detected occlusion of the artery in conjunction with other diagnostic data such as AnkleBrachial Index and symptomatology can be useful both in confirming or ruling out PAESwithout the use of more expensive and invasive methods.
