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.

New initiative boosts surveillance imaging, cuts mortality after aortic aneurysm repair

Through a statewide partnership, hospitals in Michigan drastically increased the number of patients who receive follow up imaging after undergoing aortic aneurysm repair, according to a recent study.

Postoperative geriatric syndromes signal high vulnerability and poor outcomes in older adults

Older adults who develop a new geriatric syndrome - such as dehydration, delirium, or malnutrition - after major surgery face a dramatically higher risk of poor outcomes, including more complications, fewer days spent at home, and a significantly increased likelihood of dying within a year, according to findings published in the Journal of the American College of Surgeons.

Study finds divergent relationship between different sugar sources and cardiovascular disease risk

A little of what you fancy does you good… unless it's a fizzy drink. Scientists studying the impact of sugar on the risk of cardiovascular disease have found that eating too much added sugar increases your risk of stroke or aneurysm, but eating a few treats is associated with a lower risk of cardiovascular diseases.
