Popliteal artery aneurysms are often incorrectly diagnosed and subsequently mismanaged with resultant preventable complications. We present a case of a swollen lower extremity clinically resembling a deep vein thrombosis (DVT), following tibial fracture fixation. It was treated as a DVT on the basis of ultrasound imaging at a different hospital. Subsequent imaging showed a popliteal artery pseu...

Functional popliteal artery entrapment syndrome can be difficult to diagnose, as the imaging modalities presently employed are designed to detect anatomic entrapment. We describe a novel imaging technique to aid in diagnosis in this cohort. A 22-year-old cyclist presented with exercise-limiting claudication. Magnetic resonance angiography with provocative maneuvers was nondiagnostic. Digital su...

The Falck fluorescence histochemical method was used to compare the adrenergic innervation in segments from the proximal saphenous artery, the distal saphenous artery and the popliteal artery. Adrenergic neurons penetrated the media of the proximal saphenous artery but not that of the distal saphenous artery or the popliteal artery. Responses of these vessel segments to exogenous Z-norepinephri...

For the differential diagnosis of popliteal phymas, popliteal artery aneurysms are evaluated. They are frequent among peripheral aneurysms. However, diagnosis is difficult in some patients because clinical symptoms vary. We report 2 patients who consulted our hospital for popliteal phymas. In these patients, surgery was performed via a posterior approach. In 1 patient, reconstruction was conduc...

Context: Popliteal artery entrapment syndrome (PAES) is a non-atherosclerotic cause of claudication and acute ischemia of the legs in young individuals. Objective: To report on a case of popliteal artery entrapment that was treated surgically. Case report: The patient was a 46-year-old hypertensive male diver who had been experiencing pain in his right leg for around six months, which worsened ...

BACKGROUND Paralysis of the external popliteal sciatic nerve is a frequent pathological condition that occurs after trauma. However, etiologies other than trauma, such as tumors, are also possible. The sensory collaterals of the external popliteal sciatic nerve have a small territory of innervation at the knee, and tumors involving these nerves become symptomatic after compression of the motor ...

OBJECTIVES To investigate the immediate effects of intermittent pneumatic foot and calf compression (IPFCC) on popliteal artery blood flow in symptom-free volunteers and to determine the reproducibility of color flow duplex imaging in the popliteal artery. DESIGN Cohort study. SETTING A university associated tertiary care hospital. PATIENTS Forty lower limbs of 30 volunteers without sympt...
