Abstract :
Background: Chronic SDH is a condition which usually affects the elderly population. Trauma is the most common cause of chronic subdural haematoma. Surgical Treatment of chronic subdural haematoma includes burr holes with or without drainage. In patients with membrane formation, craniotomy is considered.
Aims: To know the incidence of chronic subdural haematoma in different age groups, the risk factors for its occurrence and its surgical management.
Settings and Design: The incidence of chronic SDH in different age groups and the different surgical procedures done for its management were noted.
Materials and Methods: Fifty patients of chronic SDH who underwent surgical intervention were analysed.
Statistical analysis: Statistical evaluation was done
Results: Mean age was 62.06 years. 54% of patients were in the age group of >62 years. Mostly (56%) chronic subdural haematoma was on the right side. Right side chronic subdural haematoma patients had mean age of 60.8 years, left side chronic subdural haematoma patients had mean age of 56.7 years and bilateral chronic subdural haematoma patients had mean age of 75.6 years. Trauma (46%) was most commonly associated with chronic SDH formation. Burr hole evacuation was the preferred surgical treatment modality (92%).
Conclusion: Chronic SDH usually occurs in elderly population. Bilateral Chronic SDH is commonly seen in elderly patients. Traumatic brain injury is the commonest predisposing factor for its occurrence. In some elderly patients even a trivial injury may lead to the occurrence of chronic SDH.
