Hematoma subdural subagudo y cronico: tratamiento quirurgico en 176 pacientes. Nuestra experiencia / Subacute and chronic subdural hematomas: surgical treatment in 176 patients. Our experience

RESUMEN

Objective: to describe our surgical experience in suvacute and chronic subdural hematomas. Method: 176 patients with subacute or chronic subdural hematomas were operated between June 1998 and May 2003. Hospital records were used to ascertain data. We did a comparative analysis of the different types of surgical procedures performed. Results: the surgical procedure commonly performed was a burrhole craniostomy with subdural closed - system drainage (66 por ciento). This procedure was associated with a low rate of complications and reoperations, in comparison with the burr hole craniostomy or the craniostomy without subdural closed-system drainge. Global recurrence rate was 13 por ciento and 20,4 por ciento of the cases required reoperation. Clinical improvement rate was 72,3 por ciento. Conclusion: In our cases, burr hole craniostomy with closed-system drainge was the method of choice for the initial treatment in subacute and chronic subdural hematomas. Craniotomy should be reserved for those cases of recurrence or residual hematoma
