Abstract

Background: In evaluation of non-traumatic subarachnoid hemorrhage CT angiography (CTA) has 97-98% sensitivity and near 100% specificity. Objective: This study was conducted to evaluate the CTA findings of CT positive non traumatic subarachnoid hemorrhage. Methodology: This is an observational cross sectional study performed in Neurology department of National Institute of Neurosciences and Hospital, Dhaka over one year period (January 2019 to December 2019). Total 87 CT positive subarachnoid hemorrhage cases were purposively included in this study. All CT positive patients underwent CTA of Cerebral vessels for further evaluation. The angiography were evaluated by competent neuro-radiologists blinded about the study. Result: Among 87 patients, 40.2% were male and 59.8% were female. The average age was 53.33±11.1 years. Among the studied patient the source of bleeding was found 78.16% aneurysmal and 21.84% non-aneurysmal. 85.30% patients had single aneurysm and 14.70% had multiple aneurysm. The highest number of patient had Acom aneurysm (41.17%) followed by MCA (22.05%), ICA (13.23%), ACA (7.35%) and vertebral artery (1.14%) in order of frequency. Among the multiple aneurysm group most of the patients had combination of Acom, MCA and ICA aneurysm. Conclusion: From this study, we can conclude that CTA can be used as the primary diagnostic tool in evaluation of spontaneous SAH.

自发性蛛网膜下腔出血的ct血管造影(CTA)评价

背景:在评价非外伤性蛛网膜下腔出血时，CT血管造影(CTA)的敏感性为97-98%，特异性接近100%。目的:探讨CT阳性非外伤性蛛网膜下腔出血的CTA表现。方法:这是一项观察性横断面研究，在达卡国家神经科学与医院研究所神经内科进行，为期一年(2019年1月至2019年12月)。本研究共纳入87例CT阳性的蛛网膜下腔出血病例。所有CT阳性患者均行脑血管CTA进一步评估。血管造影由对研究不知情的有能力的神经放射科医生评估。结果:87例患者中男性占40.2%，女性占59.8%。平均年龄53.33±11.1岁。动脉瘤性出血占78.16%，非动脉瘤性出血占21.84%。85.30%为单发动脉瘤，14.70%为多发动脉瘤。以中动脉瘤最多(41.17%)，其次为MCA(22.05%)、ICA(13.23%)、ACA(7.35%)、椎动脉(1.14%)。多发动脉瘤组以Acom、MCA、ICA合并为主。结论:通过本研究，我们可以得出结论，CTA可以作为评价自发性SAH的主要诊断工具。孟加拉国国家神经科学研究所学报，2020;6(2):78-81
