Subdural hematomas: an analysis of 1181 Kashmiri patients

World Neurosurg. 2012 Jan;77(1):103-10. doi: 10.1016/j.wneu.2011.06.012.


Background: We endeavored to analyze patients of subacute and chronic subdural hematomas studied in a 4-year period at the Sher-i-Kashmir Institute of Medical Sciences, Kashmir, India.

Methods: The study was a retrospective analysis of 1181 patients of subdural hematomas. Demographic characteristics, clinico-radiologic features, operative modalities, and outcome were studied. Acute subdural hematomas were excluded from the study.

Results: The mean age was 60.4 ± 12.4 and males outnumbered females. Chronic subdural collections were more common than subacute subdural hematomas and left side predominated. Two burr holes with closed-system drainage was used in most patients. Incidence of postoperative seizures is very low. Overall recurrence rates were low; however, multilocular hematomas had the highest incidence of recurrence. Morbidity and mortality were 7.53% and 2.96%, respectively. Preoperative neurologic grade correlated with outcome.

Conclusions: Subdural hematomas are common in elderly males. Preoperative neurologic grade dictates the outcome. Multilocular hematomas have a higher chance of recurrence. Craniotomy should be reserved for recurrent hematomas, and there may be a scope of craniotomy for multilocular chronic subdural hematomas at the outset. Antiepileptic prophylaxis is not routinely recommended.
