Abstract
To investigate the risk factors for recurrence of intracranial aneurysms (IAs) after
stent-assisted coiling (SAC). Methods: Total 446 patients with a total of 486 aneurysms who underwent SAC
treatment and completed digital subtraction angiography (DSA) follow-up at our institution between January
2014 and December 2023 were enrolled. Based on imaging follow-up results, the aneurysms were categorized
into a recurrence group (n=38) and a stable group (n=448). Demographic, clinical, surgical, and morphological
characteristics were analyzed using Logistic regression. Variables with significance in univariate analysis were
included in a multivariate Logistic regression using a stepwise forward method to identify independent risk
factors. The area under the curve (AUC) of the receiver operating characteristic (ROC) curve was calculated to
assess the predictive performance of the independent risk factors. Results: Independent risk factors for
recurrence after SAC included neck (P<0.001, OR=1.287), size ratio (P<0.001, OR=1.877), Raymond scale II or
III (P=0.034, OR=2.304), and Ruptured aneurysms (P=0.010, OR=3.058). The AUC values for neck size, size
ratio, Raymond Class II or III, and ruptured aneurysms were 0.807, 0.797, 0.636, and 0.567, respectively.
Conclusion: Neck, size ratio, Raymond grade II or III, and ruptured aneurysms are significant risk factors for
recurrence following SAC of IAs.
