Abstract
Background and purpose: An intracranial vertebral artery dissecting aneurysm (iVADA) increases the risk of future subarachnoid hemorrhage, which is a severe complication with high rebleeding rates and poor outcomes. Identifying potential risk factors associated with iVADA growth is crucial for their effective management.
Methods: This observational study was carried out at a single center and included patients who had been diagnosed with iVADA based on neuroimaging findings. We divided the patients into two groups: with and without iVADA growth. Growth was defined as any enlargement of a dilated region or a morphological change in follow-up imaging. We measured the vertebral artery tortuosity index (VTI) in the contralateral vertebral artery (VA), defined as its actual length divided by its straight length. We investigated the factors associated with iVADA growth.
Results: This study included 124 patients. The median follow-up period was 7 months. We observed iVADA growth in 54 patients (43.5%), who were more likely to be current smokers (33.3% vs. 14.3%, p=0.012) and have a higher VTI (1.14±0.11 [mean±standard deviation] vs. 1.06±0.12, p=0.035) compared with those without iVADA growth. A multivariate analysis revealed that the VTI (adjusted odds ratio=28.490, 95% confidence interval=1.025-792.046, p=0.048) was independently associated with iVADA growth.
Conclusions: This study has identified an independent association between VA tortuosity and iVADA growth.
期刊介绍:
The JCN aims to publish the cutting-edge research from around the world. The JCN covers clinical and translational research for physicians and researchers in the field of neurology. Encompassing the entire neurological diseases, our main focus is on the common disorders including stroke, epilepsy, Parkinson''s disease, dementia, multiple sclerosis, headache, and peripheral neuropathy. Any authors affiliated with an accredited biomedical institution may submit manuscripts of original articles, review articles, and letters to the editor. The JCN will allow clinical neurologists to enrich their knowledge of patient management, education, and clinical or experimental research, and hence their professionalism.
