Abdominal aortic aneurysm (AAA) research focuses on understanding and developing treatments for the dilation and weakening of the abdominal aorta, the main blood vessel that supplies blood to the lower body. AAA is a potentially life-threatening condition if the aneurysm ruptures, leading to severe internal bleeding. Researchers study the risk factors, genetic factors, and pathophysiology of AAA to improve early detection, monitoring, and treatment options for patients. This research area also explores new imaging techniques and screening methods to identify individuals at risk for AAA and prevent complications.
