Objective: To explore the application value and morphological characteristics of CT angiography (CTA) in the risk assessment of intracranial aneurysm rupture. Method: We included 82 patients with intracranial aneurysms from the Third Affiliated Hospital of Bengbu Medical College from October 2018 to October 2021. All study participants underwent CTA and digital subtraction angiography (DSA) examinations using Siemens 64 row 128 slice spiral CT and Siemens DSA machines. Statistical analyses were conducted on the condition of tumor rupture. The morphological characteristics of different tumor rupture cases, and the factors influencing intracranial aneurysm rupture were analyzed. Result: The rupture rate of 82 carotid artery patients in this group was 74.39% (61/82), and the non-rupture rate of the tumor was 25.61% (21/82). The number of sub-capsules (60.66%), area ratio, Size ration (SR), Aspect ratio (AR) and length of the ruptured aneurysm were greater than that of the unruptured aneurysm. The ruptured and unruptured aneurysms did not differ significantly in the incidence of single aneurysm (91.80%) and the distribution of aneurysms. Logistic regression analysis confirmed that area ratio, SR, AR, and tumor length were important risk factors for intracranial aneurysm rupture. Conclusion: CTA examination can clarify the morphological characteristics of intracranial aneurysms and evaluate the risk of tumor rupture.
