Recurrence Rate, Burr hole drainage, Chronic sub-dural hematoma.


Objective:  One of the most often carried out procedures in the neurosurgical field is the drainage of chronic subdural hematomas (CSDHs). According to Scotti, subdural hematoma was identified radiologically as a subdural collection that was hypodense to parenchyma and manifested 21 days following trauma. This definition was based on the CT scan. In this study, we want to find the effectiveness of subdural drain in managing chronic subdural hematoma from the perspective of recurrence in our setup.

Materials and Methods:  After the procedure, the patients were admitted to the ward for 48 hours and the drain was removed after 48 hours. Then the patients were discharged and follow-up was taken one month for diagnosis of recurrence. Recurrence was labeled positive if postoperative symptomatic recurrence of hematoma that needs re-operation of any type within one month of primary surgery.

Results:  Among 85 patients mean age was 51 years with a standard deviation ± 7.55. 60(71%) patients were male and 25(29%) patients were female. Moreover s10 (12%) patients had recurrence while 75(88%) patients didn’t have recurrence.

Conclusion:  According to our research, patients with Chronic Subdural Hematoma (CSDH) had a 12% recurrence incidence following the placement of a subdural drain.
