摘 要:Background and purpose Approximately 15%–45%of patients with unruptured intracranial aneurysms have multiple intracranial aneurysms(MIAs).Determining which one is most likely to rupture is extremely important for treatment decision making for MIAs *** study aimed to develop and validate a nomogram to evaluate the per-aneurysm rupture risk of MIAs *** A total of 1671 IAs from 700 patients with MIAs were randomly dichotomised into derivation and validation *** logistic regression analysis was used to select predictors and construct a nomogram model for aneurysm rupture risk assessment in the derivation *** discriminative accuracy,calibration performance and clinical usefulness of this nomogram were *** also developed a multivariate model for a subgroup of 158 subarachnoid haemorrhage(SAH)patients and compared its performance with the nomogram *** Multivariate analyses identified seven variables that were significantly associated with IA rupture(history of SAH,alcohol consumption,female sex,aspect ratio1.5,posterior circulation,irregular shape and bifurcation location).The clinical and morphological-based MIAs(CMB-MIAs)nomogram model showed good calibration and discrimination(derivation set:area under the curve(AUC)=0.740 validation set:AUC=0.772).Decision curve analysis demonstrated that the nomogram was clinically *** with the nomogram model,the AUC of multivariate model developed from SAH patients had lower value of *** This CMB-MIAs nomogram for MIAs rupture risk is the first to be developed and validated in a large multi-institutional *** nomogram could be used in decision-making and risk stratification in MIAs patients.
