Long-term economic impact of coiling vs clipping for unruptured intracranial aneurysms.

Background: : Treatment of unruptured intracranial aneurysms (UIAs) involves endovascular coiling or aneurysm clipping. While many studies have compared these treatment modalities with respect to various clinical outcomes, few studies have investigated the economic costs associated with each procedure.

Objective: : To determine the reoperation rate, postoperative complications, and inpatient and outpatient costs associated with surgical or endovascular treatment of patients with UIAs in the United States.
