Popliteal artery entrapment

Vascular complications in athletes are common and mimic musculoskeletal injuries such as muscle sprains, fractures, and cartilage abnormalities. They include traumatic vascular injuries and more subtle pathologies like entrapment syndromes, pseudoaneurysms, arterial occlusions, and venous thrombosis. Such vascular complications may be occult on imaging and can be difficult for a musculoskeletal radiologist to diagnose, resulting in a lack of timely diagnosis and potentially limb-threatening consequences. Although the final diagnosis may require multidisciplinary input from orthopaedic, sports and exercise medicine, and vascular and interventional radiology inputs, a musculoskeletal radiologist with prior knowledge of such conditions can be the first to diagnose such conditions aiding the athlete's performance...

A 23-year-old professional distance runner with several years of exertional calf pain was diagnosed with a unique mixed type III and functional popliteal artery entrapment syndrome (PAES). Surgical reduction of the obstructing tissue allowed her to return to professional running. This case highlights the importance of including PAES in the differential for chronic intermittent lower extremity claudication and outlines the work-up required to diagnose this vascular obstruction in younger athletes.

OBJECTIVES: Popliteal artery entrapment syndrome (PAES) is a rare condition where musculoskeletal structures compress the popliteal artery (POPA) leading to vascular compromise. This study investigates the effect of dynamic plantar- and dorsi-flexion loading on POPA hemodynamic parameters to develop a robust diagnostic ultrasound-based protocol for diagnosing functional PAES. METHODS: Healthy individuals (n = 20), recreational athletes (n = 20), and symptomatic (n = 20) PAES patients were consented...

CASE: The patient, a 21-year-old female Division I track and field athlete, presents with bilateral calf pain, tightness, numbness, and swelling during activity. Initially diagnosed with chronic exertional compartment syndrome (CECS), she underwent bilateral four-compartment fasciotomies. After 4 months, she experienced persistence of some of her prefasciotomy symptoms and was referred to vascular surgery. A fibrous band was compressing the popliteal artery, making the diagnosis of popliteal artery entrapment syndrome (PAES)...

Non-traumatic lower limb ischemic diseases are extremely rare among young people. Clinically, they are mainly seen in the form of popliteal artery entrapment syndrome (PAES). In addition, with the prevalence of COVID-19 infection, more and more studies report that COVID-19 infection may lead to arteriovenous thrombosis, which could cause lower limb ischemia. This case reported that a 31-year-old male amateur football player who developed intermittent claudication after recovering from COVID-19. After 2 months of consultation, he was ultimately diagnosed with PAES...

Popliteal artery entrapment syndrome (PAES) is compression of the popliteal artery from embryologic myotendinous variation or calf muscle hypertrophy. PAES necessitates prompt diagnosis and complete release of the entrapped vasculature for symptom relief and to prevent chronic cumulative vascular damage. Our patient is a 27-year-old female referred for progressive bilateral claudication. Workup was consistent with bilateral PAES with preoperative imaging notable for an atypically proximal origin of the anterior tibial artery, which was also encased anterior to the popliteus muscle...

INTRODUCTION: Functional popliteal entrapment syndrome (FPES) is an underrecognized source of leg pain caused by dynamic compression of the popliteal vessels by surrounding musculature in the absence of anatomic abnormality. Late recognition and difficulty capturing this entity across imaging modalities can lead to significant morbidity in an often young and active patient population. Surgical outcomes and optimal diagnostic strategies remain uncertain. METHODS: We performed a retrospective cohort study of all patients undergoing surgical decompression for FPES at an academic medical center between 2018-2022...

Popliteal artery entrapment syndrome, a rare vascular disease observed in young athletes, is characterized by intermittent claudication and is often overlooked by orthopedists. Popliteal artery entrapment syndrome should be treated promptly when diagnosed, as the vascular lesion can progress. We present a case of bilateral popliteal artery entrapment syndrome in a young professional boxer with no significant family or past medical history. He had developed intermittent claudication during a boxing match with pain in both calves, making it impossible for him to continue for more than three rounds...

Popliteal artery entrapment syndrome (PAES) is where the popliteal artery is compressed-typically by the medial head of the gastrocnemius muscle. PAES is typically treated surgically with popliteal artery release with or without bypass. Graft stenosis is a recognised complication of vein grafts. These are normally treated endovascularly. Endarterectomy of venous graft stenosis may be a useful tool in selected cases, where an endovascular approach was unsuccessful. Long-term follow-up of graft stenosis endarterectomy will allow us to determine effectiveness of this method of treatment where other options have failed...

INTRODUCTION: Popliteal artery entrapment syndrome (PAES) is a rare condition in which the popliteal artery becomes compressed by adjacent soft tissue structures causing progressive claudication. Due to its low incidence, this disorder and its surgical management is poorly described in the literature. This study presents our institutional data surrounding PAES management to further optimize care of this syndrome. METHODS: This retrospective study gathered demographic, surgical, and outcome data of all patients with PAES who underwent surgical decompression at our institution from 2015 to 2022...

BACKGROUND: Numerous conditions are grouped under the generic term exercise-induced leg pain (EILP), yet clear diagnostic guidelines are lacking. This scoping review was conducted to clarify the definition and diagnostic criteria of nine commonly occurring EILP conditions. METHODS: Three online databases were searched from inception to April 2022 for any English language original manuscripts identifying, describing, or assessing the clinical presentation and diagnostic criteria of the nine most common conditions that cause EILP...

Popliteal artery entrapment syndrome (PAES) is a rare vascular disorder characterized by the compression of the popliteal artery behind the knee, primarily affecting physically active individuals. This is a case of a 36-year-old man who presented with a 1-week history of sudden-onset left leg pain. Diagnostic evaluation, including physical examination, color duplex ultrasonography, computed tomography, and magnetic resonance imaging, revealed a popliteal artery pseudoaneurysm caused by type 5 PAES. The patient underwent surgical exploration to release the entrapment, followed by an interposition graft with the ipsilateral great saphenous vein...

BACKGROUND: Popliteal artery entrapment syndrome (PAES) is an underreported and underdiagnosed condition that affects the lower extremities. Previous case reports mainly presented young and uncomplicated PAES. Here, we report the cases of complicated PAES in middle-aged patients. Furthermore, we discuss the importance of a multidisciplinary team approach from diagnosis to treatment to obtain favourable clinical outcomes against this rare disease. CASE SUMMARY: Two middle-aged patients presented with recent claudication and were diagnosed with popliteal artery obstruction due to a complicated PAES...

The accurate diagnosis of exertional leg pain in athletes is often delayed because of vague presenting symptoms and nonspecific physical examination findings. This case report outlines exertional leg pain in a runner caused by combined popliteal artery entrapment and soleal sling syndromes, 2 uncommon causes of exertional leg pain. This case report highlights the overlapping clinical presentation of these 2 diagnoses and the intricate differences in diagnostic workup and surgical approach to management.

OBJECTIVE: Popliteal Artery Entrapment Syndrome (PAES) is a rare vascular condition with significant equipoise on how to properly diagnose and evaluate relevant imaging. This can lead to misdiagnosis and delay in surgical management. The objective of this study is to describe and compare distinct imaging features of dynamic versus static images to help determine the ideal imaging modality for diagnosis of PAES. METHODS: This is a retrospective review of patients referred for PAES at a single institution...

INTRODUCTION: Functional popliteal artery entrapment syndrome (fPAES) is a subtype of PAES without anatomic abnormalities entrapment of the popliteal artery. One of the management of symptomatic fPAES is surgical exploration of the popliteal region with popliteal artery release with lysis of fibrous bands. There is a lack of data regarding the long term functional results of this surgery, most of the studies focusing on vascular patency in anatomical PAES. OBJECTIVE: The aim of this study was to assess the efficacy of surgery in functional PAES, focusing on long term physical activity return after surgery with the Tegner activity scale...

OBJECTIVE: Surgical treatment is an established method for popliteal artery entrapment syndrome (PAES), which, however, mainly derives from single centre experiences where PAES cases are centralised and treated periodically. This study evaluated clinical outcomes of surgical treatment for PAES in a clinical setting where PAES cases were not centralised. METHODS: Multicentre, retrospective cohort study using a national clinical registry. From a Japanese nationwide clinical registry, data for patients who underwent surgical treatment for PAES between 2013 and 2018, including 58 limbs from 41 institutes, were retrieved and evaluated...

The popliteal artery is located in the popliteal fossa. In addition to its other branches, it divides into two terminal branches, the anterior and posterior tibial arteries, which are subject to numerous morphological variations. The purpose of this review is to compile several authors' classifications of the patterns of terminal branching of the popliteal artery among adults and to describe the division among foetuses, as described in the current literature. Pathologies of the popliteal artery such as popliteal artery aneurysm and popliteal artery entrapment syndrome and methods for treating them, like open surgery and endovascular interventions are also discussed...

OBJECTIVE: Functional popliteal artery entrapment syndrome (fPAES) is a rare form of nonatherosclerotic claudication most often seen in young athletic patients. Diagnosis remains challenging, with various imaging modalities showing equivocal or subtle findings that may be missed. We sought to critically examine and quantitate the utility of intravascular ultrasound (IVUS) imaging, a common diagnostic tool for vascular compression syndromes, in diagnosis and characterization of fPAES. METHODS: Patients presenting to a single tertiary care center between 2019 and 2022 with symptoms of PAES but without an anatomic etiology or equivocal workup were selected...

Popliteal artery entrapment syndrome (PAES) is a type of arterial obstruction seen in athletic and young patients with no cardiovascular risk factors. It is caused by aberrant anatomy affecting the position of the popliteal artery or gastrocnemius muscle or functional obstruction resulting from a hypertrophied gastrocnemius muscle. Rich's classification has been used to define the various entities. PAES presents as unilateral claudication exacerbated by physical exertion. However, such a clinical presentation is shared amongst not only vascular diseases but also musculoskeletal diseases...
