What defines a fusiform aortic aneurysm?

A fusiform aortic aneurysm is characterized by symmetrical dilation that involves the entire circumference of the artery. This means that the aorta bulges out uniformly across its width, rather than forming an out-pouching in a localized area. This type of aneurysm typically occurs in sections of the aorta that are affected by atherosclerosis, leading to weakening of the vessel wall. The symmetrical nature of the dilation distinguishes fusiform aneurysms from other types, such as saccular aneurysms, where the abnormal bulging occurs more on one side of the vessel.

Recognizing the shape and characteristics of different types of aneurysms is crucial for diagnosis and treatment, as they may have different implications for the patient’s health, including risks of rupture or dissection. Understanding the definition of a fusiform aortic aneurysm assists healthcare professionals in monitoring and managing cardiovascular health effectively.
