EVALUATION OF BILATERAL CHRONIC SUBDURAL HEMATOMAS IN PATIENTS UNDER 50 YEARS OF AGE.

Objective: Chronic subdural hematoma (CSDH) is typically seen in elderly people with unilateral hemorrhages. The aim of this study was to examine the clinical outcomes of patients under the age of 50 who were treated at our clinic for bilateral CSDHs. Material and Method: This retrospective study included 20 patients under the age of 50 who had been diagnosed with bilateral CSDHs and treated with burr-hole drainage between 2000 and 2022 at Istanbul Faculty of Medicine, Department of Neurosurgery, Istanbul University. The patients’ demographic information, clinical data, and radiological images were obtained retrospectively from the hospital system. The data were subjected to descriptive statistical analysis using the IBM SPSS statistics 28.0.0 program. Result: There were 14 (70%) males and 6 (30%) females in our study, with a mean age of 20.5 years. The most common complaints among the patients were headaches in nine patients (45%), newly developed paresis in five patients (25%), and seizures in four patients (20%). It was discovered that 17 patients (85%) had no history of head trauma. CSDH was evacuated by bilateral burr-holes in 14 patients (70%). Three (21.4%) of 14 patients with bilateral burr-holes, and 3 (50%) of the remaining six patients were reoperated due to recurrent bleeding in the follow-up period. Conclusion: In our study, trauma history and use of antiaggregants and anticoagulants were low. More comprehensive studies on the etiology of bilateral CSDH in patients under 50 years of age are required. [ABSTRACT FROM AUTHOR]
