Clinically, fusiform or dolichoectatic aneurysms may present with headache or other symptoms related to compression of adjacent brain structures, with infarction or transient ischemic attacks, or with rupture and hemorrhage. The fusiform aneurysm increases the complexity of surgical repair by circumferential involvement of the parent vessel and involvement of the origins of distal vessels. Thoracic aortic aneurysms can cause aortic dissection (splitting of the aortic wall) and aortic rupture, leading to life-threatening internal bleeding.
