OBJECTIVE To build a prediction model that estimates the 3-year rupture risk of unruptured saccular cerebral aneurysms. METHODS Survival analysis was done using each aneurysm as the unit for analysis. Derivation data were from the Unruptured Cerebral Aneurysm Study (UCAS) in Japan. It consists of patients with unruptured cerebral aneurysms enrolled between 2000 and 2004 at neurosurgical departments at tertiary care hospitals in Japan. The model was presented as a scoring system, and aneurysms… CONTINUE READING
