Abstract

Background: Cerebral aneurysm is a disease that proceeds silently, causing few symptoms for the patient, until severe complications appear, such as: aneurysm rupture causing subarachnoid hemorrhage, cerebral hemorrhage, cerebral edema, increased intracranial pressure, brain hernias,... computed tomography angiography (CTA) can detect and provide many imaging features of cerebral aneurysms, suggest treatment options, and patients monitoring. Objectives: Characterizing the imaging features of cerebral aneurysms on CTA and evaluating the diagnostic accuracy of CTA in detecting and investigating imaging characteristics of cerebral aneurysms.

Materials and methods: This is a prospective, cross-sectional descriptive study performed in patients with suspected intracerebral hemorrhage due to ruptured aneurysm or suspected  unruptured cerebral aneurysm undergoing CTA and digital subtraction angiography at Can Tho Central General Hospital from May 2021 to May 2023. Results: The study recorded 51 suitable cases as research subjects (21 men and 30 women), discovered 48 cerebral aneurysms. 85% of patients had ruptured aneurysm, causing 100% subarachnoid hemorrhage and accompanying complications: intraventricular hemorrhage, cerebral hemorrhage, cerebral infarction. CTA accurately detected cerebral aneurysms in 94.12% of patients. The sensitivity and specificity of  CTA in detecting cerebral aneurysms were 93.02%, 100%. Conclusions: CTA is a quick, convenient and accurate imaging technology in the diagnosis of cerebral aneurysms in patients with intracranial hemorrhage, as well as in characterizing aneurysm morphology with high risk of rupture.
