Popliteal artery entrapment syndrome (PAES) is a rare vascular disease, and cases of bilateral PAES associated with distinct symptoms in each of the affected legs are very rare. In an effort to improve current understanding regarding the presentation and treatment of this condition, a case of bilateral PAES is herein described with a corresponding review of the associated literature. The overall process of diagnosing and treating one patient affected by bilateral PAES was retrospectively assessed to provide comprehensive insight regarding this disease...

Intramuscular ganglion cyst (IMGC) is a very rare lesion with an unidentified pathogeny that originates within the muscle. We encountered a case of 49-year-old man who complained of intermittent claudication in the right lower limb for 2 months. An intramuscular ganglion cyst in the biceps femoris muscle was diagnosed and located by Computed tomography angiography (CTA) and magnetic resonance imaging (MRI), which compressed the popliteal artery and resulted in ischemia in the right lower limb. Six months after surgical resection, there was no recurrence of the cyst and the popliteal artery was patency...

OBJECTIVE: Functional popliteal artery entrapment syndrome (fPAES) is an underdiagnosed and undertreated etiology of atypical claudication. Symptoms of fPAES include deep posterior muscle cramping and pain with exercise and, unlike anatomic PAES, there are seldom vascular complications. Common noninvasive diagnostic modalities include ankle-brachial index, arterial duplex Doppler ultrasound (DUS) examination, and cross-sectional imaging such as magnetic resonance angiography (MRA). Entrapment can be difficult to reproduce during diagnostic testing, requiring provocative maneuvers...

INTRODUCTION: Popliteal artery entrapment syndrome (PAES) is a rare cause of lower limb claudication in young sportsperson without cardiovascular risk factor. We reported our diagnostic approach, surgical management and short term outcomes of this syndrome, over a 10-year period. MATERIAL AND METHOD: Sportsperson with intermittent claudication systematically received color duplex ultrasonography with dynamic maneuvers in the sport medicine department. In case of PAES suspicion, diagnosis was confirmed by dynamic computed tomography or dynamic magnetic resonance angiography...

Stent fractures have been described after femoropopliteal interventions with relevant clinical sequelae, including restenosis and reocclusion. We report 2 cases of fractures of a novel interwoven nitinol stent with high radial strength and fracture resistance as a result of entrapment syndrome of the popliteal artery. ( Level of Difficulty: Advanced. ).

Vascular compression syndromes include a group of rare vascular changes due to extrinsic compression of veins or arteries by surrounding structures. These pathologies are often underestimated due to their rarity, clinicians' poor level of knowledge, and the non-specificity of their symptoms. The best known are Eagle syndrome, thoracic outlet syndrome, nutcracker syndrome, May-Thurner syndrome, Dunbar syndrome, and popliteal entrapment syndrome. This work summarizes the main ultrasonographic characteristics, symptoms, and treatments of choice for these syndromes...

Popliteal artery entrapment syndrome is a rare source of claudication in young people. We present the case of a 15-year-old male athlete who presented with intermittent numbness of his right foot with exertion. Imaging revealed classic compression from a right type III popliteal artery entrapment. The left popliteal artery was chronically occluded with a large collateral vessel. He underwent release of the accessory bands of the gastrocnemius muscle with significant arteriolysis on the right side via a posterior approach...

BACKGROUND: Popliteal Artery Entrapment Syndrome (PAES) is a rare clinical entity without a standardized algorithm for diagnosis and treatment. The objective of this study was to evaluate the clinical outcomes of a unique diagnostic and management algorithm for patients with PAES managed at a quaternary referral center. METHODS: We retrospectively reviewed patients diagnosed with PAES at a single institution between 2013 and 2021. Demographics, physical exam findings, noninvasive imaging results, and angiographic images were assessed to validate a diagnostic and management algorithm (Figure 1)...

Popliteal artery entrapment syndrome (PAES) occurs when the popliteal artery is compressed by abnormally developed or hypertrophied muscles adjacent to the popliteal fossa. When symptomatic, it most frequently presents with leg cramping while walking or running. We describe the case of an 18-year-old female runner presenting with claudication and exercise intolerance. After MRI was non-diagnostic, diagnostic ultrasound demonstrated that she had functional (Type VI) PAES. She subsequently underwent popliteal artery release surgery...

Popliteal entrapment syndrome (PES) describes a set of symptoms related to compression of the neurovascular bundle in the popliteal fossa, with popliteal artery involvement the most widely recognized variation. Popliteal vein entrapment is a rare variation which can easily go undiagnosed. This is most commonly due to an anomaly of the medial head of the gastrocnemius muscle, but other etiologies include excess adipose tissue or cysts within the popliteal fossa, popliteal artery aneurysm, fibrous bands, thickened perivenous fascia, compression by the popliteus muscle or muscular hypertrophy independent of anomalous anatomy, or variant origin of the short saphenous vein...

Popliteal artery entrapment syndrome (PAES) is an uncommon cause of lower extremity exertional claudication due to external compression of vascular structures in the popliteal fossa. A developmental anomaly due to an aberrant relationship of the artery with the surrounding myofascial structures contributes to the vascular compromise. PAES presents in younger, athletic patients without atherosclerotic risk factors. Typical presentation of unilateral or bilateral, intermittent claudication in the feet and calves specifically after exercise and relieved by rest in a young person should prompt further evaluation...

OBJECTIVE: Peripheral artery disease (PAD) is often caused by atherosclerosis. However, causes other than atherosclerosis is often overlooked. Popliteal artery entrapment syndrome (PAES) and popliteal artery adventitial cystic disease (PACD) are two common nonatheromatous causes of claudication and critical limb ischemia. The purpose of this study is to present early results of treatment of PAES and PACD involving the lower limbs. METHODS: From December 2019 to February 2021, 10 patients with PAES underwent surgeries, and 1 patient with PAES received conservative treatment...

CASE: Tibial plateau fractures can be associated with arterial injuries or dysvascular limbs, particularly in settings of trauma. Dysvascular limb in the setting of fracture is commonly due to dissection of the artery. Entrapment of the artery within the fracture is rare. We report a 48-year-old man who presented with left popliteal entrapment within a left tibial plateau fracture status-post external fixation and stent placement in the popliteal artery. CONCLUSION: Findings from this case highlight entrapment of an artery as a mechanism of a dysvascular limb in the setting of high-energy lower-extremity fractures and specifically for tibial plateau fractures...

Claudication of the young patient is a very rare symptom for orthopaedic surgeons and it is often overlooked. We report a rare case of popliteal artery entrapment syndrome (PAES), discovered during a vascular claudication following post-traumatic anterior instability of the knee. The diagnosis was confirmed by CT angiography which showed a PAES, with a pathway in the inter-condylar notch. The patient had a releasing of the trapped vessel by myomectomy, with disappearance of vascular symptoms six months later...

Popliteal artery entrapment syndrome (PAES) is a rare condition that produces calf claudication in young patients. It is most commonly a result of aberrant anatomy of the popliteal fossa. If undiagnosed, PAES can lead to acute ischemia and a threatened limb as a result of complete arterial occlusion or embolism. Ice hockey is a contact sport, and slashing on the covered legs is well described as a strategy and contact point. We present a unique case that highlights a blunt popliteal artery injury in a young player with an underlying type 2 PAES...
