BACKGROUND

Data on Computed tomographic (CT) pattern of stroke abound in literature but they are predominantly from studies done in the Western world. Though most of the reports agree that ischaemic rather than haemorrhagic stroke is prevalent in most climes,no strictly radiology based study can be quoted in the Port Harcourt area. Thus there is the need for accurate data on stroke pattern in Nigerians of the South-South region.

AIMS

This study was done to establish the CT pattern of stroke seen in University of Port Harcourt Teaching Hospital (UPTH) and to determine the relationship between the different stroke patterns and age, sex, including time of presentation.

METHODOLOGY

A prospective study of 203 subjects with clinical diagnosis of stroke who had CT of the brain performed during a 12month period (November 2012 to November 2013).A 2-slice helical CT was used to obtain images in the axial plane. Images were classified as normal or abnormal scans. Abnormal scans were analyzed as ischaemic infarcts, intracerebral haemorrhage, subarachnoid haemorrhage (SAH), subdural haematoma, abscess, neoplasm, meningitis, and cerebral atrophy. The clinical diagnosis, age, sex and time of presentation of the patients were recorded. Statistical analysis was done with the Statistical Package for the Social Sciences (SPSS) software version 20.0.Means were compared using Student's t test. Pearson's correlation coefficient was used to correlate CT findings with clinical diagnosis ,age, and sex.P values < 0.05 were considered significant.

RESULTS

The age distribution of the study population ranged from 6-90 years with a mean of 58.3+14.9years. The over 70 age group was most frequent with 24.1% of the subjects. Males were predominant at 51.7% of the sample size. Findings of ischaemic cerebrovascular disease (CVD) were more common than haemorrhagic CVD at 63.2%.

CONCLUSION

This study revealed a higher incidence of ischaemic stroke compared to haemorrhagic stroke.

背景

关于中风的计算机断层扫描（CT）模式的数据在文献中大量存在，但它们主要来自西方世界进行的研究。尽管大多数报告都认为，在大多数地区缺血性中风而非出血性中风更为普遍，但在哈科特港地区却没有严格基于放射学的研究可供引用。因此，需要获取关于南南地区尼日利亚人中风模式的准确数据。

目的

本研究旨在确定哈科特港大学教学医院（UPTH）所见中风的CT模式，并确定不同中风模式与年龄、性别以及就诊时间之间的关系。

方法

对203例临床诊断为中风的患者进行前瞻性研究，这些患者在12个月期间（2012年11月至2013年11月）接受了脑部CT检查。使用2层螺旋CT在轴向平面获取图像。图像被分类为正常或异常扫描。异常扫描被分析为缺血性梗死、脑内出血、蛛网膜下腔出血（SAH）、硬膜下血肿、脓肿、肿瘤、脑膜炎和脑萎缩。记录患者的临床诊断、年龄、性别和就诊时间。使用社会科学统计软件包（SPSS）20.0版进行统计分析。采用学生t检验比较均值。使用Pearson相关系数将CT结果与临床诊断、年龄和性别进行相关性分析。P值<0.05被认为具有统计学意义。
