CTA, three-dimensional CTA, and magnetic resonance angiography (MRA) have shown reliable results in detecting aneurysms equal to or grater than 2 to 3 mm in diameter. Of these, 14 aneurysms (in six men and eight women with mean age of 63 years) underwent surgical repair. Objective: However, treatment may also be indicated for patients with unruptured aneurysms smaller than 7 mm if young and with known risk factors for development and rupture of intracranial aneurysms. J Vasc Surg Cases Innov Tech. The location of the aneurysms was equally distributed between the internal and common carotid arteries. Surgical repair was safe and effective with no significant morbidity or mortality and good midterm stroke prevention. If the outer diameter exceeds 5.5 cm, the aneurysm is considered to be large.
