Background and Objective: Chronic subdural hematomas (CSDH) is frequently encountered in neurosurgical practice. The aim of this study was to investigate the factors associated with the outcome of Burr Hole Craniotomy.
Methods: This study was conducted on 116 patients with CSDH in Be'sat Hospital, an educational hospital, in Kurdistan province, Iran. We used Glasgow outcome scale (GOS) at times of discharge and 1 month after stitch removal as favorable outcome. Student t-test or corresponding nonparametric test (Mann-Whitney U test) and logistic regression were used to assess the relationship between investigated variables and favorable outcome.
Results: The results indicated that the chance of success after surgery in patients with CSDH was different based on several variables. The chance of cure after surgery among CSDH male patients (OR = 12.5), patients who have no atrophy (OR = 25.0), patients with no cardiovascular diseases (OR = 7.14), patients who had no medical complications after surgery (OR = 2.08), and patients with higher GCS score at the time of hospitalization (OR = 1.31) was higher.
Conclusions: Burr hole drainage technique is a simplified, efficient and reliable method of treating patients with CSDH. Our study highlights various factors including female gender, diffuse brain atrophy, postoperative medical complications, a previous history of cardiovascular disease, and lower GCS score at the time of admission can be related to patients' worse outcome.
