Abstract

Background: Lately, there has been an increased utilization of computed tomography angiography (CTA) as the preferred first-line modality for the evaluation and diagnosis of most cerebral vascular lesions. Objective: The objective of this study was to evaluate suspected intracranial vascular cases, using CTA at a major referral tertiary hospital in South West Nigeria. Materials and Methods: This was a hospital-based retrospective study of suspected intracranial vascular cases in all ages and both sexes that had CTA from January 2011 to December 2018. Data were analyzed with IBM SPSS version 23.0, and P < 0.005 was considered statistically significant. Results: A total of 128 patients were studied, the mean age was 44.1 ± 17.7 years, and male: female ratio was 1:1.06. The leading clinical diagnoses were as follows: intracranial aneurysms (34/128), subarachnoid hemorrhage (27/128), intracranial vascular tumors (26/128), brain hemorrhage from vascular abnormality (19/128), and arteriovenous malformations (AVMs) (10/128). At CTA, 61 patients had vascular abnormalities: intracranial aneurysm was seen in 63.9% with a peak age range of 41–60 years, and the leading location of aneurysms was posterior cerebral artery (18.8%), followed by posterior communicating artery (16.7%) and the cavernous segment of the internal carotid artery (16.7%). AVMs were more common in patients aged 40 years and below (91.7%) in males (66.7%) and in the parietal lobe. Intracranial aneurysms were 3.25 times as common as brain AVMs. Conclusion: Intracranial aneurysms are the predominant vascular lesions, occurring mostly in the older age group. AVMs occurred mostly in younger people, more in males, and predominantly in the parietal lobes. The hospital incidence of aneurysms to AVMs was 3.25:1.
尼日利亚队列中疑似颅内血管异常的颅骨断层造影血管造影评估
背景:最近,计算机断层摄影血管造影术(CTA)作为评估和诊断大多数脑血管病变的首选一线方式,得到了越来越多的应用。目的:本研究的目的是在尼日利亚西南部一家主要转诊三级医院使用CTA评估疑似颅内血管病例。材料和方法:这是一项基于医院的回顾性研究,对2011年1月至2018年12月接受CTA检查的所有年龄和性别的疑似颅内血管病例进行了回顾性研究。数据采用IBM SPSS 23.0版进行分析,P<0.005被认为具有统计学意义。结果:共研究了128名患者,平均年龄为44.1±17.7岁,男女比例为1:1.06。主要临床诊断如下:颅内动脉瘤(34/128)、蛛网膜下腔出血(27/128)、颅内血管瘤(26/128),血管异常引起的脑出血(19/128)和动静脉畸形(AVMs)(10/128)。在CTA中,61名患者出现血管异常:63.9%的患者出现颅内动脉瘤,峰值年龄范围为41-60岁,动脉瘤的主要位置是大脑后动脉(18.8%),其次是后交通动脉(16.7%)和颈内动脉海绵体段(167%)。AVMs在40岁及以下患者(91.7%)、男性(66.7%)和顶叶更常见。颅内动脉瘤的发病率是脑动静脉畸形的3.25倍。结论:颅内动脉瘤是主要的血管病变,多发生在老年组。AVMs主要发生在年轻人中,更多发生在男性中,主要发生在顶叶。动脉瘤与动静脉畸形的住院发病率为3.25:1。
