OBJECTIVE To evaluate magnetic resonance imaging (MRI) and digital subtraction angiography (DSA) findings in popliteal artery entrapment syndrome. METHODS Seven limbs of 6 patients (5 men and 1 woman; mean age, 36 +/- 12 years) with popliteal artery entrapment syndrome were evaluated retrospectively. Both MRI and DSA were performed on each affected limb. RESULTS MRI findings established the diagnosis of type-3 popliteal artery entrapment syndrome in 4 limbs, and type-2 in 3 limbs. Abnormal MRI findings included popliteal artery thrombosis with aneurysm in 2 limbs (29%), popliteal artery thrombosis without aneurysm in 1 limb (14%), aberrant fibrous band in 3 limbs (43%), aberrant thick muscle bundle in 1 limb (14%), insertion anomaly of medial head of the gastrocnemius muscle (MHG) in 3 limbs (43%), lateral deviation of the MHG in 4 limbs (57%), hypertrophy of the MHG in 1 limb (14%), and atrophy of the MHG in 2 limbs (29%). Deviation of the popliteal artery in 4 limbs (57%) and distal crural embolic occlusions in 2 limbs (29%) were detected with both angiography and MRI imaging. DSA was diagnostic in 2 limbs of 1 patient, and MRI was diagnostic in all limbs examined. CONCLUSIONS Popliteal artery entrapment syndrome should be considered in patients younger than 50 years of age with isolated popliteal artery stenosis or occlusion. MRI is the preferred imaging modality for diagnosis of entrapment syndrome, and may obviate the use of DSA.

UI	MeSH Term	Description	Entries
D007383	Intermittent Claudication	A symptom complex characterized by pain and weakness in SKELETAL MUSCLE group associated with exercise, such as leg pain and weakness brought on by walking. Such muscle limpness disappears after a brief rest and is often relates to arterial STENOSIS; muscle ISCHEMIA; and accumulation of LACTATE.	Claudication, Intermittent
D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D001157	Arterial Occlusive Diseases	Pathological processes which result in the partial or complete obstruction of ARTERIES. They are characterized by greatly reduced or absence of blood flow through these vessels. They are also known as arterial insufficiency.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
