Abstract: (58 Views) |
Background: The study investigates the relationship between aneurysm morphology and incidence angle measured by Computed Tomography Angiography (CTA) and the risk of intracranial aneurysm (IA) rupture. Materials and Methods: We analyzed data from 150 patients with intracranial aneurysms, comparing those with ruptured and non-ruptured aneurysms. Statistical methods were applied to identify key risk factors for rupture. Results: Significant differences were observed in aneurysm morphology, incidence angle, and risk scores between the ruptured and non-ruptured groups. Factors such as irregular aneurysm shape, larger diameter, aspect ratio (AR), size ratio (SR), and incidence angle were associated with higher rupture risk. Conclusion: CTA-measured aneurysm morphology and incidence angle, along with patient-specific factors, are crucial in assessing the risk of IA rupture. These findings can guide clinical decision-making and improve patient outcomes. |
