Physical inactivity promotes the development of cardiovascular diseases. However, few data exist examining the vascular consequences of short-term reductions in daily physical activity. Thus we tested the hypothesis that popliteal and brachial artery flow-mediated dilation (FMD) would be reduced and concentrations of endothelial microparticles (EMPs) would be elevated following reduced daily ph...

BACKGROUND Popliteal fossa pseudoaneurysms as a result of trauma are not uncommon. However, spontaneous pseudoaneurysms as a result of non-traumatic rupture of posterior tibial artery (PTA), anterior tibial artery (ATA), or tibioperoneal trunk (TPT) artery segment are extremely rare. We report a case of spontaneous popliteal fossa pseudoaneurysm resulting from spontaneous avulsion of the ATA an...

Uncommon diseases of the popliteal artery include cystic adventitial disease, popliteal artery entrapment syndrome (PAES) and popliteal artery aneurysm (PAA). Because all of these conditions may present with pain or intermittent claudication, imaging is crucial for differentiating them and directing management. Delayed diagnosis can lead to major complications, including acute limb ischemia. Ou...

Popliteal artery injury is a very rare complication of anterior cruciate ligament (ACL) reconstruction. The authors experienced a case of popliteal arterial pseudoaneurysm after re-revision of ACL reconstruction using Rigidfix for femoral tunnel fixation. Pseudoaneurysm was detected in knee magnetic resonance imaging, which caused pain, limit of motion, common peroneal nerve palsy, leg swelling...

Pseudoaneurysms of the popliteal artery are a rare clinical entity, accounting for <4% of all popliteal aneurysms. Accurate diagnosis and effective intervention is required to prevent potentially limb-threatening complications. We present the case of a 37-year-old man with acute limb ischaemia due to distal calf vessel thrombosis secondary to a popliteal pseudoaneurysm that was managed with cov...

The authors evaluated risk factors potentially associated with the development of popliteal artery atherosclerosis in a population-based study and compared them with factors linked to carotid wall intimal-medial thickness. The Atherosclerosis Risk in Communities (ARIC) Study is a longitudinal investigation of cardiovascular disease in 15,800 individuals. The present analyses are based on the ba...

We recently showed that 5 days of reduced daily physical activity impair popliteal artery, but not brachial artery, flow-mediated dilation (FMD). However, the mechanisms by which physical inactivity causes leg vascular dysfunction are unclear. We reason that a reduction in leg blood flow-induced shear stress is a primary underlying mechanism by which reduced daily physical activity impairs popl...

OBJECTIVE/BACKGROUND The objectives were to report the management and outcomes of a 96-year-old man who presented with an acutely swollen right leg due to a ruptured popliteal aneurysm, and to review the relevant literature. METHODS A ruptured popliteal artery aneurysm is a rare diagnosis and is one that is often missed at time of presentation. Previous case reports have documented successful...

INTRODUCTION Blunt trauma of the popliteal fossa is an uncommon cause of lower limb ischemia and it is associated with a high risk for limb loss. REPORT The case of a young man with anterior dislocation of the right knee joint causing post-traumatic popliteal artery occlusion and severe lower limb ischemia is reported. DISCUSSION To our knowledge we first report a multidisciplinary approach...
