Prognostic value of the amount of post-traumatic subarachnoid haemorrhage in a six month follow up period.
Clinical and radiological patterns from 148 patients with post-traumatic subarachnoid haemorrhage (TSAH) were analysed with specific regard for the amount and distribution of blood in subarachnoid spaces to verify if these variables have any influence on overall outcome. The degree and extent of TSAH were classified according to Fisher's criteria: in 93 patients it was grade 1, in 36 grade 2, in 13 grade 3, and in six grade 4. ⋯ The results of the present study confirm that TSAH is a negative prognostic factor. Whereas the degree of TSAH is mainly related to clinical conditions at admission, the presence of subarachnoid blood clots both in basal cisterns and over the cerebral convexity indicates a poor outcome.
