Hematoma subdural crónico: una enfermedad del adulto mayor / Chronic subdural hematoma: a disease of elderly people

RESUMO

The lack of specificity and heterogeneity of the clinical picture of chronic subdural hematoma, hampers its diagnosis. Aim: To report the experience of a Neurosurgical Service in chronic subdural hematoma. Patients and methods: One hundred patients (77 male, mean age 77ñ13 years) with chronic subdural hematoma were analyzed. Results: The main clinical presentations were mental status changes (50 percent) and progressive focal neurological deficit (46 percent). Five cases presented as a transient neurological deficit. All patients were treated with burr hole drainage. Thirteen had recurrence of the hematoma and they were reoperated. The surgical mortality was 3 percent. Eighty seven patients were followed for a mean of 66 months. Eighty one of these had a complete recovery, 6 had permanent neurological deficit and 2 of these were unable to care for themselves. Bad prognosis was associated with the absence of a previous trauma to explain the hematoma and symptoms of dementia as the clinical presentation. Conclusions: Most patients with chronic subdural hematoma treated with burr hole drainage have a good outcome:
