The bulging aneurysm can put pressure on a nerve or the surrounding brain tissue. Aortic aneurysms can occur anywhere in the aorta and may be tube-shaped (fusiform) or round (saccular). Cerebral aneurysms are 90% saccular aneurysms (also known as berry aneurysms), unlike aortic aneurysms, which are about 94% fusiform. Symptomatic aneurysmssuch as those causing back or abdominal painhave a higher risk of rupture than asymptomatic aneurysms. An AAA should be repaired when the risk of rupture outweighs the risks of surgical repair. All three tunica layers are involved in true aneurysms (fusiform and saccular).
