Vascular & Endovascular

This channel includes news on non-coronary vascular disease and therapies. These include peripheral artery disease (PAD), abdominal and thoracic aortic aneurysm (AAA and TAA), aortic dissection, pulmonary embolism (PE), critical limb ischemia (CLI), carotid artery and stroke interventions, venous interventions, deep vein thrombosis (DVT), and interventional radiology therapies. The focus on most of these therapies is minimally invasive, catheter-based procedures performed in a cath lab.

NEJM: Cholesterol efflux capacity is inversely related to CIMT, CAD risk

Cholesterol efflux capacity from macrophages has a sizeable inverse association with carotid intima-media thickness (CIMT) and the risk of angiographic coronary artery disease (CAD) that is independent of HDL cholesterol, according to a study published in the Jan. 12 issue of the New England Journal of Medicine.

AngioDynamics books positive Q2

AngioDynamics, a developer of medical devices for the minimally-invasive treatment of cancer and peripheral vascular disease, has reported slightly higher net income in its financial results for the fiscal 2011 second quarter, which ended Nov. 30, 2010.

How RESILIENT is SFA Stenting?

Study results evaluating stenting of the superficial femoral artery (SFA) have been conflicting, with stent fractures playing a major role in patency loss. However, newer nitinol stents show more promise than previous-generation stents because of their flexibility and durability.

Stroke Feature: High stroke death, readmissions require multi-pronged solution

Two-thirds of discharged ischemic stroke patients died or were rehospitalized within one year, suggesting a need for multidisciplinary strategies to improve outcomes, according to a study published online Dec. 16 in Stroke.

JVS Feature: Carotid stenting more costly, riskier than endarterectomy

Utilizing carotid artery stenting (CAS) as the gold standard to repair stenosis remains unlikely despite improvement in outcomes due to higher costs and an increased risk of mortality and stroke compared to carotid endarterectomy (CEA), which is particularly true for patients who present with neurological symptoms, based on a study published online Nov. 19 in the Journal of Vascular Surgery.

CDC: Stroke drops to fourth leading cause of death in U.S.

Chronic lower respiratory diseases have replaced stroke as the third leading cause of death, moving stroke to fourth on the list, according to new data published by the Centers for Disease Control and Preventions (CDC) National Center for Health Statistics.

NEJM: Rivaroxaban may prove useful for VTE

Rivaroxaban offers a simple, single-drug approach to the short-term and continued treatment of venous thrombosis that may improve the benefit-to-risk profile of anticoagulation, according to the EINSTEIN researchers, who published their results Dec. 4 in the New England Journal of Medicine.

Commonality of stroke can be prevented, says new AHA/ASA guidelines

To better understand the onset of a first stroke, members of the American Heart Associations Stroke Council and the American Stroke Association, worked to assess what common factorseither modifiable or non-modifiableputs patients most at risk.
