title: Popliteal Artery Entrapment Syndrome.
abstract: Popliteal artery entrapment syndrome (PAES) may be implicated as a cause of lower leg pain in active individuals. Though a relatively rare syndrome, it is likely underdiagnosed. History often includes exertional lower leg pain, cramping, and/or paresthesias rather quickly relieved by rest, though examination may be benign. When suspected, imaging is recommended to assess anatomic variations versus functional entrapment of the artery in the calf. Because there are a number of diagnostic modalities available, it seems prudent to begin with noninvasive testing, such as ultrasound with Doppler and provocative maneuvers. Thereafter, advanced imaging (magnetic resonance imaging/magnetic resonance angiography) or arteriography may help identify a specific anatomic obstruction. Once confirmed, surgical exploration has historically been the treatment of choice, though less invasive interventions have been proposed. Though most patients reportedly return to high-level training, decision-making remains highly individualized. Further study of younger, active individuals with PAES will help to further define these criteria.
