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.

FB-EVAR is safe and effective for treatment of aortic aneurysms, study shows

A recent study revealed that endovascular repair of complex aortic aneurysms using fenestrated and branched endografts provides a safe and effective alternative to open surgical repair, with the lowest ever reported mortality rate in this patient population, according to researchers at The University of Texas Health Science Center at Houston and Memorial Hermann Heart and Vascular Institute Aortic Center.

Study casts doubt on promotion of 'Heat not Burn' products as less harmful alternative to cigarettes

The impact on lung cells of Heat not Burn products--a hybrid between traditional cigarettes and electronic vaping devices--may be no less harmful than that of conventional cigarettes, suggest the findings of a small comparative study, published online in the journal Thorax.

New model to better predict risk of abdominal aortic aneurysms

An abdominal aortic aneurysm (AAA) can be a ticking time bomb if undiscovered in time. However, researchers at the University of Pittsburgh are developing a new model to better predict at-risk patients. And the tools they are using apply mechanical testing to the human body - which is itself a complex machine.

Study identifies genes linked with abdominal aortic aneurysm

A veteran's study identified more than a dozen genes associated with abdominal aortic aneurysm (AAA) that could be used to better identify people at risk for the often-deadly condition, according to new research published today in the American Heart Association's flagship journal Circulation.

Temple research suggests new way to prevent abdominal aortic aneurysm therapeutically

The main thoroughfare that carries oxygen-rich blood from the heart to the abdomen is known as the abdominal aorta.

Doxycycline is not effective in reducing the growth of abdominal aortic aneurysm

A new landmark study by researchers at the University of Maryland School of Medicine (UMSOM) found that patients with a vascular condition, called an abdominal aortic aneurysm, received no benefits from taking a common antibiotic drug to reduce inflammation.

Abdominal aortic aneurysm in older men associated with levels of leukocyte subsets

Abdominal arterial (or aortic) aneurysm in older men is associated with levels of certain subtypes of white blood cells, a study from the University of Gothenburg shows.

Loyola Medicine expert detects and treats abdominal aortic aneurysm

When 64-year-old Robert Johnson of Highland, Indiana thought he had kidney stones, he visited his primary care physician who couldn't see anything of concern. He pushed, saying "I'm not making up this pain. It's waking me up every night."

Common cardiac blood test before surgery can predict post-operative complications

A common cardiac blood test done before surgery can predict who will experience adverse outcomes after most types of surgery, says an international study led by Hamilton researchers.

Study offers promising methodology to capture biomechanical behaviour of aneurysm

An abdominal aortic aneurysm is a focal dilation of the abdominal aorta, that if not treated, tends to grow and may rupture. The most common treatment is EndoVascular Aneurysm Repair (EVAR), which requires patients to undergo lifelong postoperative surveillance based on computed tomography angiography (CTA) due to the possible appearance of complications. These complications may again lead to aneurysm dilation and rupture.

New cause of serious aortic disease discovered

Researchers have discovered that a family of lipids (fats) contribute to the development of a serious aortic disease, by driving clotting in the blood vessel wall.

Researchers track where tetracycline antibiotics go in human cells

We know that antibiotics treat bacterial infections. We also know why they work. Tetracycline antibiotics, for example, stop bacteria from making protein. Like a boot on a wheel, the drugs bind to the bacterial cell's ribosome--where protein is made--and prevent it from working. Without protein, the bacteria weaken and die.

Perioperative beta blockers could increase deaths and strokes one year after surgery

During the 12 months after undergoing noncardiac surgery, patients with or at risk for heart disease who were treated with the beta blocker metoprolol for 30 days were less likely than patients who received a placebo to have a heart attack, but more likely to die or have a stroke, according to research presented at the American College of Cardiology's 67th Annual Scientific Session.
