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.

UC research examines role of a metabolite in the development of abdominal aortic aneurysm

Each year, about 200,000 people in the United States are diagnosed with a bulge in the lower part of the aorta, the main artery in the body, called an abdominal aortic aneurysm (AAA).

COVID-19 infection may promote aortic aneurysms and new treatment may slow its growth

The intravenous delivery of immune-modulating cells may someday slow the expansion of bulges in the aorta, known as abdominal aortic aneurysms.

Drugs targeting FXR1 may treat vascular proliferative diseases

Vascular diseases, including myocardial infarction, stroke, renal failure, and peripheral vascular disease, continue to account for one third of all mortality in the United States, Europe, and the developing world (World Health Organization, 2021).

Computational model of the cardiovascular system for predicting and preventing aortic ruptures

An abdominal aortic aneurysm (AAA) causes the wall of a person's aorta, the largest artery in the body, to weaken and bulge outward. If left untreated, it can continue to grow and eventually rupture, which can lead to life-threatening bleeding.

Study finds higher mortality rate among Black men after elective surgery

Black men have a higher death rate within 30 days of surgery compared with any other subgroup of race and sex, finds a study of adults in the United States published in The BMJ.

UMSOM researchers unravel the molecular components involved in abdominal aneurysms

When the artery that supplies the stomach and the liver forms a bulge that ruptures, this medical emergency results in the deaths of 50 percent of patients before they reach the hospital.

Fibromuscular dysplasia and abdominal aortic aneurysm have a “shared complex genetic architecture”

One disease is more common in people assigned female at birth, while the other is more common in people assigned male at birth.

Abdominal aortic aneurysm repair in cancer patients linked to poor postoperative outcomes

Elective abdominal aortic aneurysm (AAA) repair in patients with a cancer diagnosis is associated with several poor postoperative outcomes according to a newly published study from researchers at the University of Missouri School of Medicine.

Study may pave the way for mechano-medical approaches to treating abdominal aortic aneurysm

Abdominal aortic aneurysm (AAA) is a complex and life-threatening vascular disease with high incidence worldwide. Termed the silent killer, most AAAs are asymptomatic, often going undetected until rupture, and involve a poorly understood set of mechanical and biochemical events.

Erectile dysfunction medication found to intensify abdominal aortic aneurysms in mice

In a laboratory study in mice, sildenafil, a commonly used erectile dysfunction medication, was found to worsen abdominal aortic aneurysms, indicating additional research may be needed to determine if the medication may have the same effect on people, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

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.
