Aneurysms are abnormal bulges or weakening in the wall of a blood vessel, typically an artery, which can lead to potentially life-threatening complications such as rupture and hemorrhage. Research in this area focuses on understanding the underlying causes of aneurysms, developing improved diagnostic tools and treatments, and identifying risk factors for the development of aneurysms. This research is important for improving patient outcomes and reducing the morbidity and mortality associated with aneurysm-related complications.
