Abdominal aortic aneurysm (AAA) is a ballooning of the aorta, the largest blood vessel in the human body, which extends into the abdomen. If the wall of this blood vessel becomes weakened, it can stretch, "balloon" out and rupture. A rupture, if left untreated, can lead to life-threatening internal bleeding. The exact cause of this condition is unknown. However, it often occurs in older adults, especially males, those with a high cholesterol level, and in smokers. There also tends to be a genetic link to this disorder.
UT Southwestern Medical Center is the No. 1 hospital in Dallas-Fort Worth – the nation's fourth-largest metro area – and ranks among the top 50 hospitals nationally in 10 specialties ranging from brain to heart care, according to U.S. News & World Report's annual Best Hospitals report released today. Six of the specialties rank in the top 25.
A new guideline aimed at helping clinicians identify the difficult-to-diagnose acute aortic syndrome is published in CMAJ (Canadian Medical Association Journal).
A team of researchers and health care providers at Hamilton Health Sciences and McMaster University have launched Canada's first study to remotely manage patients after surgery.
The main thoroughfare that carries oxygen-rich blood from the heart to the abdomen is known as the abdominal aorta.
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 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.
A breakthrough medical technology can save the lives of children with heart defects. Scientists have developed the first-ever heart valve that grows with the child, reducing the need for risky heart surgeries in the future.
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."
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.
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.
It is the 'silent killer' that claimed the life of Albert Einstein and affects 1% of men over the age of 65, but researchers at the University of Dundee believe they may be able to reduce the number of fatalities caused by abdominal aortic aneurysms.
When James Inman, 59, first experienced chest pain one night, he tried to brush it off and go back to sleep. But the pain became unbearable and Inman felt like something was wrong, so he called 911.
A new study of New York City firefighters has found that exposure to 9/11 World Trade Center dust is associated with a significantly increased long-term risk of cardiovascular disease.
The notion that more medical errors occur in July compared to other months due to an influx of new medical school graduates starting their in-hospital training does not apply to heart surgery, according to research in The Annals of Thoracic Surgery, published by Elsevier.
The system connects the arteries to the veins. There are 100,000 miles of blood vessels in the adult human body.
The pivotal trial to determine the safety and effectiveness of a modular device designed to be the first completely off-the-shelf endovascular solution for aortic aneurysms involving the visceral branch vessels is successfully underway with its first surgery at UNC Hospitals in Chapel Hill, NC.
New University of Alberta research is paving the way for the first medical treatment to help protect people from cardiovascular disease by boosting the body's natural defenses.
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.
Paracetamol or other painkillers taken during pregnancy are unlikely to cause asthma in the child, according to a large study by researchers at Karolinska Institutet and Queen Mary University of London.
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.
