Risk factors for growth of conservatively managed unruptured intracranial aneurysms

Purpose Unruptured intracranial aneurysms (UIAs) occur in 2–3% of the adult population, but, once discovered, do not always require treatment. Untreated patients are usually followed with serial imaging to identify interval growth. In this study, we assessed the risk and risk factors for growth in a homogenous series of patients with conservatively managed UIAs.
