ASSESSMENT OF CEREBROVASCULAR ACCIDENTS ON COMPUTED TOMOGRAPHY

Abstract

BACKGROUND: Cerebrovascular accident is acute onset of a neurological deficit due to
vascular cause. CT is an imaging modality performed quickly and safely on critically ill patients,
and is relatively inexpensive.Methods: This prospective study includes sixty patients with
clinical diagnosis as CVA with or without persistent neurological deficit. Non contrast CT was
done in each case,contrast study was done when indicated .The results of study were
systematically collected, assimilated and analyzed to draw valid conclusions.Results:The range
of patient age was found from 27 – 83 years. Mean age + SD of patients in this study were
57.5+13.2 years. Male to female ratio was found to be 1.1:1. Hypertension was the commonest
risk factor in this study and 23.3% cases had history of diabetes mellitus and11.6% cases had
previous history of TIA/CVA. 43 cases (71.7%) were diagnosed clinically as ischemic stroke and
17 cases (28.3%) were diagnosed clinically as hemorrhagic stroke. Conclusion: CT brain
remains an essential imaging study in stroke patients due to its sensitivity for the detection of
blood and infarction. CT scan done to differentiate the two types of stroke and thus helps in
improved management and therapeutic outcome in patients of stroke
