Introduction: We present a series of 158 cases of patients admitted to our Neurosurgery ward due to the presence of a Chronic Subdural Haematoma (CSDH) as the main pathology.
Materials and Methods: Clinical histories of 158 patients in a 3-year period were reviewed. The criteria for CSDH diagnosis used were an intracranial/extra-axial accumulation, iso-hypodense relative to brain parenchyma on CT-scan. The variables analyzed were sex, age, pharmacologic and traumatic history, clinical presentation, radiologic findings, type of treatment, corticoids at discharge, and outcome.
Results: Sex distribution showed a 65% male predominance. Mean age was 75 years. Anticoagulants or antiplatelet drugs had been taken by 46% of patients. A previous traumatic event was confirmed in 56% of cases. Cognitive impairment was present in 43%, headache in 35%, and focal neurological deficit in 82%. Side distribution was 45% left, 33% right, 21.5% bilateral y 0.5% interhemispheric. The average width was 19 mm, with a mean midline displacement of 7 mm on CT-scan. Surgical treatment was performed in 85% of patients, consisting in a burr-hole technique in all cases. Recurrence rate was 9%.
Conclusion: The prototypical CSDH patient is an elderly male, with history of traumatic event, and presenting with focal neurological deficit. The burr-hole surgical technique provides radiological resolution of the hematoma and clinical improvement in 90% of cases.
