Popliteal artery entrapment syndrome is a rare abnormality of the anatomical relationship between the popliteal artery and adjacent muscles or fibrous bands in the popliteal fossa. The anterior suprapatellar fat pad is enlarged with mass effect on the adjacent suprapatellar recess and quadriceps tendon 1-3. Magnetic resonance imaging (MRI) analysis of the knee was incon-clusive and no muscular abnormality could be identified. A developmental anomaly due to an aberrant relationship of the artery with the surrounding myofascial structures contributes to the vascular compromise. Popliteal Artery Entrapment Syndrome: Role of Imaging in the Diagnosis. Magnetic resonance imaging is reported as the diagnostic method of choice when there is clinical evidence or duplex Doppler imaging suggestive of popliteal artery entrapment syndrome 24). Objectives: The purpose of this study was to report our experience with popliteal artery entrapment syndrome (PAES) with special emphasis on the applicability of duplex ultrasound scanning (DUS) when diagnosing PAES. Two forms of PAES exist: anatomical and functional. Awareness of the imaging findings is impotant to tailor the examination for confirmation of the diagnosis and surgical planning. Popliteal artery entrapment syndrome (PAES) is an uncommon cause of lower extremity claudication. Popliteal artery entrapment syndrome (PAES) is a relatively rare condition that occurs in young patients as a result of anomalous anatomic relationships between the popliteal artery and the surrounding musculotendinous structures. Popliteal artery entrapment syndrome was diagnosed non-invasively by multidetector CT and MRI. Because all of these conditions may present with pain or intermittent claudication, imaging is crucial for differentiating them and directing management. 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.

History often includes exertional lower leg pain, cramping, and/or paresthesias rather quickly relieved by rest, though examination may be benign. Eur Radiol 8(6):1025-1029. It is caused by an anomalous relationship of the gastrocnemius muscle and artery in the popliteal fossa resulting in extrinsic arterial comression. Introduction. Anderson Stuart as a cause of acute lower-extremity intermittent claudication. However, to this date, it remains underdiagnosed. The angiographic imaging demonstrated the deviation of the popliteal artery out of its natural tract. Popliteal artery entrapment syndrome: clinical, noninvasive and angiographic diagnosis. (PMID: 9683714) [3] Di Cesare E, et al. (PMID: 7949691) Popliteal artery entrapment syndrome is a condition caused by direct compression of the popliteal artery as it passes within or exits the popliteal fossa. All of these methods rely on the . In type I entrapment (Heidelberg classification system), the popliteal artery has an atypical course; in type II, the muscular insertion is atypical; and in type III, both conditions are present. PAES can be further classified by anatomical type (I-VI, table 1). Popliteal artery entrapment syndrome is a condition characterized by constriction of the popliteal artery by adjacent muscles, tendons or fibrous tissue. McDonald PT, Easterbrook JA, Rich NM, et al. Discussion. Popliteal artery entrapment syndrome (PAES) is an important albeit relatively uncommon circulatory disease that affects the legs of young adults causing leg pain during exercise. The following is a case report of a 19 year old female, in whom popliteal artery entrapment syndrome was diagnosed, and successfully treated surgically. PAES is caused by an aberrant anatomic relationship between the popliteal artery and the neighbouring muscles and tendinous structures [1]. Background. Popliteal artery entrapment syndrome (PAES) is an important, yet unusual cause of vascular claudication. When the condition is diagnosed and treated early, a full recovery is expected, and your symptoms should disappear. Popliteal artery entrapment syndrome (PAES), described by Stuart in1879, is an uncommon limb-threatening vascular entity comprising approximately 0.17%-3.5% of the general population in the United States (US) [1] [2] [3] .
