Specific guidelines are available for management of small (<2.5 cm) and large sized (4.0 cm <) SCH. But, literature is sparse for treatment of moderate sized SCH (2.5-4.0 cm).
MATERIAL and METHODS: In a retrospective analysis of 32 patients, with moderate sized acute SCH, external ventricular drainage (EVD) tube was inserted for evaluation of ICP and evacuation of cerebrospinal fluid. All patients with ICP >25 mmHg underwent emergency SCH evacuation. Postoperatively, EVD was continued for 48-72 hours for ICP monitoring. Patients showing no improvement or persistent ventriculomegaly underwent ventriculoperitoneal shunt (VPS) insertion for the management of hydrocephalus.
RESULTS: 29/32 patients needed operative intervention either in the form of hematoma evacuation or shunt placement. 10 patients improved to GOS 5 and 7 to GOS 4. Overall mortality was 25% (n=8). Despite SCH evacuation, none of the patients with ICP >40 mmHg experienced good outcome (p<0.0001).
CONCLUSION: 47% of patients with moderate sized SCH need surgical evacuation. EVD insertion not only helps in ICP management but also includes the ability to gradually decompress ventricular system by varying the outflow pressure. Apart from radiologic findings, ICP measurement should be a guideline in management decisions.
