Arterial aneurysms are abnormal bulges or ballooning of blood vessels, typically occurring in arteries. Resulting from weakened vessel walls, common causes include atherosclerosis, genetic factors, and trauma. The most prevalent type is the abdominal aortic aneurysm (AAA), often asymptomatic until rupture, posing a life-threatening emergency. Early detection through imaging studies, such as ultrasound or CT scans, is crucial for intervention. Treatment options range from monitoring small aneurysms to surgical repair for larger ones. Lifestyle modifications, blood pressure control, and addressing risk factors are essential preventive measures. Timely diagnosis and management play a vital role in preventing complications associated with arterial aneurysms.
