Abdominal Aortic Aneurysm News and Research

RSS

Abdominal aortic aneurysm (also known as AAA, pronounced "triple-a") is a localized dilatation of the abdominal aorta exceeding the normal diameter by more than 50 percent. It is caused by degeneration of the aortic wall, but the exact etiology remains unknown.

Mayo Clinic research shows that revascularization has reduced need for amputations by 40%

Peripheral arterial disease is a common circulation problem in which reduced blood flow can lead to complications that jeopardize the limbs, possibly even requiring amputation. Procedures known as revascularization have reduced the need for amputations 40 percent over two decades, Mayo Clinic research shows.

Handheld ultrasound devices: an interview with Warren Ortmann, Signostics

Ultrasound devices use sound waves to image the organs of the body safely, without the use of radiation. The sound waves are produced by applying a current to a piezoelectric crystal housed in a transducer. The crystal alters shape and creates a sound wave.

High HDL levels block development of aneurysms in the aorta

New research provides early evidence that 'good' cholesterol may possess anti-aneurysm forming properties. In laboratory-based investigations, scientists found that increased levels of high-density lipoproteins (HDL), the so-called good cholesterol, blocked the development of aneurysms - dangerous 'ballooning' in the wall of a blood vessel - in the body's largest artery, the aorta.

Similar survival rates with endovascular, open aneurysm repair

Endovascular and open repair of abdominal aortic aneurysm result in similar long-term survival rates, say researchers in TheNew England Journal of Medicine.

Study: Notch 1 signaling activated in abdominal aortic aneurysmal tissue

A gene known to be involved in cancer and cardiovascular development may be the cause of inflammation in the most common form of aortic aneurysm and may be a key to treatment, according to research from Nationwide Children's Hospital.

HDL may protect against abdominal aortic aneurysm

High levels of high-density lipoprotein cholesterol inhibit the formation of abdominal aortic aneurysm, findings from experimental mouse models suggest.

Endovascular repair for abdominal aortic aneurysms has low rate of complications

A minimally invasive procedure known as endovascular repair used for abdominal aortic aneurysms has a low rate of complications, even in high-risk patients such as those with kidney, heart or lung problems, a Mayo Clinic study shows.

Study raises cautionary note about preferential use of endovascular technique for ruptured AAA

A new study raises a cautionary note about the increasing use of a minimally invasive procedure to repair ruptured abdominal aortic aneurysms, according to vascular surgeon Dr. Jae Sung Cho of Loyola University Medical Center.

Rescreening men for aneurysm likely to be a cost-effective option

Aneurysm screening for men aged over 65 is cost effective and rescreening those at highest risk, at least once, should be considered, suggests a study published on bmj.com today.

Aneurysm rescreening for high risk men should be considered

Aneurysm screening for men aged over 65 is cost effective and rescreening those at highest risk, at least once, should be considered, suggests a study published on bmj.com today.

Currently available online information about abdominal aortic aneurysms need improvement

During the last decade use of the Internet has begun to pervade all aspects of modern life, including an "e-health revolution" where patients may research health issues online before seeking professional consultation. However according to researchers from Leeds in the United Kingdom (U.K), the quality and readability of online patient information specifically for abdominal aortic aneurysms (AAAs) is poor and requires significant improvement.

Contrast-enhanced ultrasound effective method for abdominal aortic aneurysms

Contrast-enhanced ultrasound is an effective, noninvasive method for monitoring patients who undergo endovascular repair for abdominal aortic aneurysms, according to a new study published in the journal Radiology.

Cardiovascular emergencies may benefit from regionalized systems of care

Experts are proposing a new model of care collaboration to diagnosis, treat and follow patients who present with various emergent cardiovascular conditions which require rapid, resource-intensive care and confer a high risk of mortality, in an article published April 24 in Circulation.

Endovascular aneurysm repair associated with lower mortality rates

A burst aneurysm in the abdominal aorta-the largest blood vessel in the body- is a deadly condition. In fact, about half of these patients don't make it to the hospital in time. Those who do more often than not face open surgery to repair the blood vessel. This study finds that a minimally invasive interventional radiology treatment for ruptured aneurysms called endovascular aneurysm repair is safer than open surgical repair and is associated with lower mortality rates, say researchers Society of Interventional Radiology's 37th Annual Scientific Meeting in San Francisco, Calif.

SIR to showcase latest minimally invasive treatments at 37th annual meeting

Health, science and medical reporters are invited to register now for the Society of Interventional Radiology's 37th Annual Scientific Meeting March 24 at Moscone Center (North), San Francisco, Calif. The meeting's theme, "IR Evidence," was chosen to focus on the results of care-changing investigations that showcase research into minimally invasive treatments that provide treatment options, advance patient care and improve quality of life.

Surgeon volume and in-hospital mortality for open AAA repair

Researchers from Southwestern Texas University's Division of Vascular and Endovascular Surgery and the Veterans Medical Center, both in Dallas, have reported that composite surgeon (overall) volume rather than operation-specific (annual) surgeon volume is a key determinant of in-hospital mortality for elective open abdominal aortic aneurysm surgery.
