We investigated the effect of cerebrovascular atherosclerosis stenosis (CAS) on irregular morphology of IAs.Patients and Methods: This single-center case-control study included consecutive patients with IAs at our institution from September 2011 to September 2018. Cases were patients with irregular IAs, and age- and location-matched controls were patients with regular IAs. Conditional logistic regression models were used to assess the relationship between angiographic variables of CAS and aneurysmal irregularity.Results: A total of 140 cases of irregular IAs and 140 controls were included in the analysis. Sixteen patients with irregular IAs (11.4%) and eleven patients with regular IAs (7.9%) had > 50% parent artery stenosis; however, the differences were not statistically significant between these two groups. In addition, no significant between-group differences were observed in distributions of the cerebrovascular stenosis, number of arterial stenoses, and location of the stenosis. In the final adjusted conditional logistic regression model, only aneurysm size (≥ 7 mm) was significantly associated with irregular IA morphology (P = 0.022). Moreover, 89 cases of irregular IAs and 89 controls were included in the analysis of unruptured IAs (UIAs). In the final adjusted conditional logistic regression model, only aneurysm size (≥ 7 mm) was significantly associated with irregular UIA morphology (P = 0.020).Conclusion: Our findings indicate that the morphological irregularity of unruptured intracranial aneurysms is more related with aneurysm size rather than cerebrovascular atherosclerosis. Further studies are needed to use prospective data to identify causative factors responsible for aneurysmal irregularity.Keywords: atherosclerotic stenosis, intracranial aneurysms, irregular morphology, risk factors, aneurysm sizeQi PFeng XLu JWang JHu SWang DDove Medical Pressarticleatherosclerotic stenosisintracranial aneurysmsirregular morphologyrisk factorsaneurysm sizeGeriatricsRC952-954.6ENClinical Interventions in Aging, Vol Volume 16, Pp 665-674 (2021)
