Nonatheromatous Popliteal Artery Disease.

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. 2 patients with PACD underwent surgery. Patient data including age, gender, etiology of vascular pathology, diseased vessel, surgical method, and hemodynamic status were collected retrospectively. RESULTS: The mean follow-up duration was 5.64 ± 3.72 months (range, 1-12 months). All patients had their symptoms improved or resolved. The success rate of surgery was 100%, the rate of freedom from reintervention for any reason was 100%. There were no death, bleeding, embolism, or skin ulcers during late follow-up. CONCLUSIONS: PAES and PACD require early diagnosis and intervention, and early surgery may lead to good early- and mid-term results.

About a rare cause of calf pain in an athlete: the popliteal artery entrapment syndrome (a case report).

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. Through this case, we wanted to draw the attention of orthopaedic surgeons to the fact that the PAES can be asymptomatic. Its symptomatology can be triggered by a traumatic instability of the knee. Its presence represents a risk of lesion of the popliteal artery during arthroscopic ACL reconstruction. Therefore, it is important to think about this disease if a calf pain occurring after a ligament injury of the knee.

Bilateral Popliteal Artery Entrapment Syndrome in a Young Female NCAA Division-I Collegiate Basketball Player: A Case Report.

CASE: Popliteal artery entrapment syndrome (PAES) is rarely on the differential for exertional lower extremity pain in the young athlete. This article illustrates a case of a 20-year-old female National Collegiate Athletic Association (NCAA) Division-I college basketball player who was diagnosed with PAES after conservative treatment of medial tibial stress syndrome and comprehensive evaluation for chronic exertional compartment syndrome. She received bilateral popliteal artery releases through a posterior approach and made an asymptomatic return to Division-I collegiate basketball. CONCLUSION: PAES is a rare potentially limb-threatening disease that must be included on the differential of young athletes who present with exertional lower extremity pain.

Popliteal Artery Entrapment Syndrome.

A 37-year-old military service-member was referred to physical therapy with a greater-than-6-month history of low back pain with intermittent and worsening left posterolateral lower-leg pain and paresthesia with activity. He was diagnosed by his primary care physician with exertional compartment syndrome and referred to orthopaedic services. Following examination, the physical therapist ordered a duplex ultrasound, which demonstrated an anomaly at the popliteal artery, resulting in a diagnosis of popliteal artery entrapment syndrome, confirmed by computed tomography angiography and magnetic resonance imaging.

Popliteal artery entrapment syndrome secondary to a femoral osteochondroma.

BACKGROUND: Osteochondromas (or exostoses) are the most common benign tumors of the bone. Vascular complications of these tumors are rare but have been increasingly reported in recent literature. AIM: Throughout an unusual case report of popliteal artery entrapment syndrome secondary to a femoral osteochondroma, we highlight the necessity of thorough clinical and radiological examinations as well as meticulous and prompt surgical resection. CASE REPORT: A 27-year-old male patient, who had been diagnosed with multiple osteochondromas and had never been operated on, presented with a one-year history of exercise-induced left calf pain, paresthesias of the left leg and pallor in cold weather. After radiographic and Computed Tomography angiographic evaluation, we diagnosed distal femur osteochondroma associated with an arterial compression of the left popliteal artery. A surgical treatment of all lesions was performed. No operative complications occurred. The pain was relieved. Good postoperative results have been noticed. CONCLUSION: Popliteal aretery entrapment syndrome may be caused by solitary or multiple osteochondromas around the knee. Therefore, prophylactic resection of exostoses in the surrounding area of a vessel should be performed. Moreover, the orthopedic surgeon should consider and prevent vascular complications during surgical resection of knee osteochondromas.
