We retrospectively evaluated the clinical features and therapeutic outcomes in 13 consecutive patients with the diagnosis of fusiform aneurysm of the vertebrobasilar system. Four patients (31%) presented with compressive symptoms and 10 (77%) with ischemic symptoms; one patient presented with both types of symptoms. No patient presented with rupture of the fusiform aneurysm. Based on the attending physician's choice, treatment included antiplatelet therapy in five patients, anticoagulation in seven, and no medication in one. Five patients died, four treated with antiplatelet agents and one not treated with any medication. The cause of death was progressive brainstem ischemia in three, sepsis in one, and gastrointestinal bleeding in one patient. All seven patients who received anticoagulants were alive, with no recurrence of symptoms or hemorrhagic complications after a mean follow-up period of 18 months. Based on previous and current series, we conclude that rupture of fusiform aneurysms is rare. Our results suggest a more favorable outcome in the management of these aneurysms with anticoagulation therapy to prevent progressive thrombosis and embolization.
