CT assessment of subarachnoid haemorrhage. A comparison between different CT methods of grading subarachnoid haemorrhage.
A number of different CT classifications of subarachnoid haemorrhage (SAH) were applied to a consecutive series of 50 patients with aneurysmal SAH. The best correlation with delayed ischaemic deficits (DID) was obtained with a score formed by the sum of the individual cisternal grades except that of the cortical subarachnoid space. The findings emphasize the significance of the extent of the SAH, rather than the presence of a localized cisternal clot with regard to the development of DID.
