Stereotactic aspiration of intracerebral haematoma: significance of surgical timing and haematoma volume reduction.

We reviewed 63 patients with primary intracerebral haemorrhage (PICH) in basal ganglia treated by computed tomography (CT)-guided stereotactic aspiration to evaluate the impact of surgical timing and degree of haematoma volume reduction on neurological outcome evaluated with Glasgow Outcome Score (GOS). In 19 patients operation was performed within 24h from the symptom onset with more than 60% of haematoma volume reduction. At 3 weeks 11 patients (58%) achieved a favorable outcome (GOS 4 or 5). In the other 44 patients only 10 (23%) recovered to GOS 4 or 5. These differences were statistically significant. At 6 months a still larger proportion of patients with early radical decompression showed favorable outcome, however, the difference was not statistically significant. The results demonstrate that early and radical stereotactic aspiration provided a better neurological outcome at the early recovery phase, though the beneficial effect on the final outcome was not significant statistically.
