An aneurysm occurs when a portion of blood vessel walls becomes weak and subsequently dilates. A saccular aneurysm is a localized outpouching of the aortic wall, and it is the shape of a pseudoaneurysm. Depending on the location of the aneurysm, a rupture or clot can be life-threatening. A fusiform aneurysm refers to an aneurysm that has a circumferential and ballooning shape. An AAA should be repaired when the risk of rupture outweighs the risks of surgical repair. Fusiform-shaped aneurysm: Bulges or balloons out on all sides of the aorta; relatively more common. Aorta is the biggest blood vessel of humans and it is responsible to deliver blood from a person's heart to various other parts of the body. In false aneurysms, blood escapes between tunica layers and they separate. They are termed cylindrical if it involves a somewhat longer length. An aneurysm can be characterized by its location, shape, and cause. what is a saccular aneurysm. The saccular aneurysm, a localized outpouching that communicates with the arterial lumen by a narrow or wide opening, is the most common type, accounting for 93% of all aneurysms ( Zinman and Libertino, 1982 ).
