CLINICAL AND IMAGING CHARACTERISTICS AND TREATMENT OUTCOMES IN PATIENTS WITH UNRUPTURED INTRACRANIAL ANEURYSMS AT S.I.S CAN THO INTERNATIONAL GENERAL HOSPITAL
Main Article Content
Abstract
Background: Unruptured intracranial aneurysms are estimated to occur in 3.2% of the general population. Unruptured intracranial aneurysms are often asymptomatic, but rupture leads to subarachnoid hemorrhage with very serious consequences. Each treatment method for unruptured intracranial aneurysms has different benefits and risks, and it is currently unclear which method is ideal. Objectives: To describe the clinical and imaging features and evaluate treatment outcomes in patients with unruptured intracranial aneurysms at S.I.S Can Tho International General Hospital. Materials and methods: A cross-sectional descriptive study was conducted on 108 patients treated for unruptured intracranial aneurysms at S.I.S Can Tho International General Hospital. Results: From January 2025 to December 2025, 132 unruptured intracranial aneurysms were detected, and
108 aneurysms were treated. The mean patient age was 57.8 ± 13.1 years, with females comprising
64.8%. Headache was the most common presenting symptom (79.6%). The mean aneurysm size was 5.9 ± 2.6 mm. Saccular aneurysms accounted for 95.4%, while irregular, multilobulated, or daughtersac-containing morphologies were observed in 48.1%. The most frequent aneurysm locations were the internal carotid artery (54.6%) and the middle cerebral artery (23.1%). The treatment modalities applied were as follows: surgical clipping in 24/108 (22.2%), endovascular coiling in 39/108 (36.1%), flow diversion in 44/108 (40.8%), and stent-assisted coiling in 1/108 (0.9%) patients. Overall, 95.4% of patients achieved a favorable outcome following treatment, defined as a Glasgow Outcome Scale– Extended (GOS-E) score ≥ 5. Conclusion: Treatment of unruptured intracranial aneurysms yields favorable results. However, the decision to treat must be individualized, based on patient-specific characteristics, and reached through shared decision-making between the patient and the treating physician, given that the risk of serious adverse events persists.
