ABSTRACT

Background: Stroke is the most common cause of morbidity and mortality worldwide. There are two types of stroke, ischaemic stroke and haemorrhagic stroke. The most important diagnostic tool of acute stroke is CT scan of brain. In acute ischaemic stroke, there are diverse CT scan findings especially in respect of anatomic location of ischaemic change or character. After the event of acute ischaemic stroke the patient may become completely stable or may develop complications or may die within a few days. Objective: This study is designed to determine the relationship between CT scan findings and short term outcome of acute ischaemic stroke. Methodology: This is a prospective observational study done in Rangpur Medical College Hospital during the period of July, 2015 to June,2017. Total 60 cases were enrolled from the admitted patients in Medicine and Neuro medicine department of Rangpur Medical College Hospital, in this study by purposive consecutive sampling technique fulfilling the inclusion and exclusion criteria. CT scan of brain was done for each patient after taking informed consent. Radiological evidence of acute ischaemic stroke was ascertained by radiologist. Data were collected from each patient and/or attendants by taking meticulous history, clinical examination and relevant investigations. Clinical status and afterwards outcome after 7 days of admission was measured by Modified Rankin Scale. All data were collected in individual predetermined case record form and analysed by SPSS version 17.0. Results: Total number of patients was 60. Male female ratio was 1.2:1. During study period 22% (N=13) died out of 60 patients. Thirty six (60%) patients had infarction due to proximal occlusion of artery mostly middle cerebral artery and 24(40%) patients had lacunar infarcts. Morbidity was measured by modified Rankin scale at the time of admission and during follow up after 7 days. Morbidity was found to be significantly increased in proximal occlusion stroke than lcunar sroke (P value <0.05). Mortaliy was also significantly higher in proximal occlusion stroke than lacunar stroke (P value 0.04). Conclusion: In this study it is found that CT scan findings can predict the short term outcome of acute ischaemic stroke. This will provide insight about better understanding in predicting accuracy of CT scan of brain.
