The fusiform aneurysms are mostly located in the posterior circulation, mainly in the VA with a ratio of 20% vs 80% in anterior vs posterior circulation [ 14 ]. An aneurysm occurs when a portion of blood vessel walls becomes weak and subsequently dilates. An aneurysm can be characterized by its location, shape, and cause. AAAs typically begin below the renal arteries (infrarenal) but may include renal arterial ostia; about 50% involve the iliac arteries. We conducted a systematic review for articles on the treatment of FIA with . It typically grows by ~1mm every year, and surgery is recommended when diameter . The aneurysm's location was just distal to the ophthalmic artery, where the entire circumference of the carotid was involved. They are thought to arise from traumatic, mycotic, or congenital etiologies. These aneurysms are also frequently filled with thrombus. They typically occur in arteries; venous aneurysms are rare. pre-existing neurological conditions, location of the aneurysm, extent of bleeding, and time elapsed between the rupture and treatment. The more common fusiform-shaped aneurysm bulges or balloons out on all sides of the blood vessel. In larger lesions, mass effect, partial thrombosis, and poor wall malleability frequently preclude direct vessel reconstruction and encourage the use of cerebral bypass techniques.

For fusiform aneurysms the basilar location showed the largest maximal diameter (11.7 mm, range 8.5-17 mm) and, for dolichoectasia, disease affecting both the vertebral and basilar arteries showed the largest diameter (11.5 mm, range 7-16 mm). Approximately 85% of aneurysms are located in the anterior circulation, predominately at junctions or bifurcations along the circle of Willis.
