Comparative study on the Out Come of Burrhole Craniostomy for Chronic Subdural Haematoma with or Without Drainage Tube.
Pak J Neuro Surg Jan ;14(1):15-8.

Object: To determine the role of drainage after burr hole craniostomy on the outcome of chronic subdural hematoma in terms of brain damage, infection, hospital stay and recurrence rate. Study Design: Quasi experimental. Place and Duration of Study: Neurosurgery department Bahawal Victoria Hospital Bahawalpur from Jan 2009 to Dec 2009. Methods: Forty patients were divided in two equal groups. In group A drain was placed and in group B patients were managed only with burrhole. Results: The study group was composed of 30 male and 10 female patients (mean age, 58.63 years, age ranges 40-70 years). In 35 patients there was a history of trauma prior to the onset of major neurological symptoms. In group A patients drain was placed. Drainage tube damaged the brain in 2 patients, Infection in 4 patients and seizure in 3 patients. In group B infection in 2 patients, seizure in one patient. Recurrence of CSDH in 2 patients in group A and 4 patients in group B. Conclusion: Chronic subdural hematoma is a discrete clinical entity. Trauma appears to be the primary causative factor that resulted in chronic subdural hematoma Bur hole drainage under local anesthesia forms the basis of treatment. Drainage tube after evacuation of hematoma should be avoided because it can damage the brain parenchyma and prevalence to infection with drain.
