The role of computed tomography in the evaluation of cerebrovascular accidents

Lokesh Kumar T., Vinay N. Gore, G. C. Patil


Background:Cerebrovascular accidents (CVA) or stroke ranks first in frequency and important among all the neurological diseases of adult life. 50% of neurological disorders in a hospital are of this type. It is the third leading cause of death throughout the world. The prolonged morbidity and extended hospitalization required by these patients makes the disease one of the most devastating in medicine. The purpose of the present study was to document the presence or absence of hemorrhage or infarct, to determine the size, location of infarct, reasonably assessing the territory to blood vessels involved and to detect the incidence of negative cases of clinically suspected stroke.

Methods:100 cases admitted to KIMS, Hubli and those referred to the NMR scan centre, Hubli with the clinical diagnosis of acute stroke were taken up for the study. The study was done from May 2010 to April 2012.

Results:Out of 100 patients clinically suspected of CVA, submitted for CT scan study of the brain, 69 patients had infarcts, 21 patients had hemorrhage, 8 patients had CVT, 1 patient had SAH and 1 patient had normal scans. Infarcts (69%) formed the major group of the CVA cases involving most commonly the LMCA territory in 10 (14.49%) patients. Hemorrhage (21%) formed the second major group of CVA cases involving most commonly the RMCA territory 9 (42.85%) patients.

Conclusions:CT scanning is a gold standard technique for the diagnosis and management of stroke and can be ideally done in all cases.
