Abstract
ABSTRACT: Objectives: This study was performed to establish role of CT Brain in establishing frequency of different type and subtypes of stroke in Pakistani population and to correlate CT findings with risk factors and duration of onset of symptoms that lead patient to take admission in hospital and outcome of different types of stroke. Methodology: A sample of hundred patients was taken from SOCIAL SECURITY HOSPITAL MULTAN ROAD LAHORE over a period of nine months starting from October 2014 to June 2015.A prospective study with convenient sampling technique was performed. Equipment used was 64 slice TOSHIBA CT scanner machine. Patients with incomplete data, pediatric age group to age 14 years, stroke due to trauma, infections or tumours were excluded from this study. A detailed questionnaire was used to collect data from the patients that included age, sex, type of stroke, time of onset of symptoms, location of lesion on CT brain, odema of cerebral tissues, midline shift predisposing risk factors like HTN, DM, oldage, high cholesterol levels, CLDetc and outcome of stroke and time of death in some cases was recorded.The collected data was analyzed by SPSS-20. Results: Shows that infarctive stroke was more prevalent type of stroke in Pakistani population and the frequency increases with increasing age and stroke was more prevalent in men than in women.It shows that subdural hematomas were more prevalent out of hemorrhagic strokes than other subtypes of extraaxial type of hemorrhagic strokes.Complications like odema of cerebral tissues,midline shift and disabilities were more common in hemorrhagic strokes than in infarctive strokes.Also the cases of stroke due to rupture of a blood vessel presented earlier to hospital because of early onset of symptoms as compared to cases of stroke due to blockade of a blood vessel.
Highlights
Stroke is one of the leading causes of death in developed as well as in underdeveloped countries of the world

Out of hundred stroke cases,54% were male and 46% were females. Another such study was performed on the West Europe that shows that incidence of stroke is 33% higher in males than in females.The result I got from this study is that incidence of infective stroke is greater as compared to hemorrhagic stroke like out of hundred stroke cases 82% are of infective stroke and 18% were diagnosed to have hemorrhagic stroke
Summary
Stroke is one of the leading causes of death in developed as well as in underdeveloped countries of the world. For example in Pakistan, stoke prevalence study conducted on adult pashtun community residing in Karachi reported a prevalence of 4.8% which was alike in men and women. This was the highest ever reported prevalence of stroke in world. Computed tomography (CT) is a non-invasive diagnostic imaging procedure that uses a combination of x-rays and computed technology to produce horizontal and axial images called slices of the body. A CT-scan shows images of any part of the body which are more detailed than standard x-rays. CT has played a great role in diagnosis of Corresponding Author: Dr Nayab Alia, Associate Professor, Madina Teaching Hospital University Medical and Dental College, Faisalabad
