Study design

Descriptive study.

Place & Duration of study

Department of Neurosurgery, Jinnah Postgraduate Medical Centre Karachi, from August 2017 to December 2019.


Patients of all age groups and both genders were included. CT scan brain was used to confirm the diagnosis of CSDH at least three weeks after the insult. Patients with recurrent CSDH were excluded. All the patients underwent burr-hole with aspiration of hematoma and subdural drain placement. Postoperative complications were noted. All patients were followed in outpatients department and CT Scan brain was repeated. All of them were observed for clinical improvement or otherwise.

In 130 (81.8%)patients there was a history of trauma, 24 (15.1%) were using medication while 5 (3.1%) patients had bleeding disorder. Preoperative GCS score was 9.62+2.45 and postoperative GCS score 13.17+1.83. Postoperative complication rate was 15.09%. Four (2.5%) patients had CSF leak, 3 (1.9%) developed pneumocephalus, and wound infection occurred in 3 (1.9%) patients. Fourteen (8.8%) patients developed recurrent CSDH.
