Catheter drainage for chronic subdural hematoma.
Pak J Neuro Surg Jan ;23(2):85-92.

Objective: To evaluate the functional outcome of patients having chronic subdural hematoma (CSDH) in terms of Glasgow Outcome Scale subjected to single burr-hole craniostomy and catheter drainage without prior subdural space irrigation.Materials and Methods: This study was performed in Neurosurgery Department, PGMI Lady Reading Hospital, Peshawar, Pakistan from January 01, 2016 to December 31, 2016. Through a Descriptive Case Series, 116 patients presenting with CSDH were included in the study in a consecutive manner, subjected to single burr hole craniostomy and catheter drainage and followed up for up to 06 weeks.Results: The mean age group of the sample was 37.31 +/- 10.74 years, of which 69% were male and 31%female patients respectively. At the presentation, there were 37.06% of patients in Class I group with GCS13-14, 47.41% of patients in Class II group with GCS 9-12 and 15.52% of patients in Class III group with GCS 3-8. On follow up, Glasgow Outcome Score of the sample was 4.04 +/- 0.75, with 84.48% favorable and 15.52% unfavorable outcome respectively.Conclusion: This study suggested that chronic subdural hematoma managed with single burr hole subdural catheter drainage is associated with a high frequency of a favorable outcome in terms of Glasgow Outcome Score. Admission Glasgow Coma Scale of less than 8 and advanced age are associated with lesser frequency of favorable outcome and more prone to unfavorable outcomes.
