Nature of lesion in cerebrovascular stroke patients: clinical stroke score and computed tomography scan brain correlation.
OBJECTIVE
To differentiate between cerebral infarct and intracerebral haemorrhage on the basis of clinical stroke score (Siriraj Stroke Score and Guy's Hospital Score) and to find out the sensitivity and overall accuracy of these scoring systems by comparing it with CT scan findings.


METHODS
Two hundred patients with acute stroke were analysed by Siriraj and Guy's Hospital Score simultaneously CT scan was performed and patients with subarachnoid haemorrhage, tuberculoma, tumours and trauma were excluded.


RESULTS
CT scan revealed cerebral infarction in 152 (76%) patients and cerebral haemorrhage in 48 (24%) patients. The sensitivity of Siriraj Stroke Score was 92.54% for infarction and 87% for haemorrhage (equivocal and infratentorial cases were excluded) and it's overall accuracy was 91.11%. The Guy's Hospital Score had a sensitivity of 93.42% for infarction, 66.66% for haemorrhage and overall accuracy was 87%.


CONCLUSIONS
Siriraj Stroke Score is easier to use at bed side and has a greater accuracy (especially in diagnosis of haemorrhage) than the Guy's Hospital Score.
