Fusiform aneurysms have different underlying pathologies, hemodynamics, anatomical distributions, natural histories, and treatments compared to the saccular variety. Renal artery aneurysms are uncommon, and are generally discovered during diagnostic procedures performed in relation to other conditions. Infrarenal saccular aneurysms generally require tube graft replacement because the coexistent atherosclerosis makes patch repair difficult. A saccular aneurysm is a rounded sac containing blood, that is attached to a main artery or one of its branches. Inherited conditions, especially those that affect connective tissue (such as Marfan syndrome and Ehlers-Danlos syndrome ).

Weakness- all 3 layers of the arterial wall. Rather than ballooning off to one side, fusiform aneurysms lead to a widening of the artery and do not have a definite neck. The most common cause is arteriosclerosis. Often there are no symptoms, but a ruptured aneurysm can lead to fatal complications. High blood pressure creates stress along the walls of blood vessels in the lenticulostriate arteries, which promotes atherosclerosis (i.e., the build-up of fatty deposits in the artery) and increases smooth muscle cell proliferation. Mycotic aneurysm develops after an infection (typically in your heart valves) has weakened an artery wall. A false aneurysm may be the result of a prior surgery or trauma.

In addition, these drugs can cause hemorrhage from preexisting vascular abnormalities such as AVMs or saccular aneurysms because of their ability to cause surges of increased systemic blood pressure to high values. The first symptom of a cerebral aneurysm is subarachnoid hemorrhage. About 75% of people with a ruptured brain aneurysm survive longer than 24 hours. The shape of an aneurysm is described as being fusiform or saccular, which helps to identify a true aneurysm.
