Abstract

Loefgren and Zwetnow (1972), in 1972 found that intracranial arterial bleeding is an essentially self-limiting process. Haematoma volume is determined by the interplay of 5 factors. Three of these factors, counterpressure, haemostasis and possibly vasospasm act to reduce bleeding. The remaining two factors, CSF outflow and cerebral homeostasis, consisting of autoregulation and increased O2 extraction, compensate for the presence of an intracranial haematoma
