RESUMEN
ObjectiveTo investigate the effects of minimally invasive key-hole drainage for treating acute subdural hematoma.MethodsThirty-five patients with acute subdural hematoma treated by key-hole drainage were retrospectively analyzed.CT-oriented key-hole drainage was performed to aspirate,liquefy and drain hematoma.The transfixion pin was removed after hematoma was basically cleared within 1 to 3 days.ResultsHematoma volume decrease was greater than 80％ by follow-up CT 24 hours postoperatively.Headache and vomiting in the preoperative conscious patients were significantly relieved after key-hole drainage.Glasgow Outcome Score (GOS) was 5 points in 16 patients,4 points in 15 and 3 points in four six months postoperatively.One patient was complicated with hydrocephalus and two with epilepsy.ConclusionsKey-hole drainage with disposable transfixion pin selective employed for patients with acute subdural hematoma is effective and has few complications.The treatment notably improves prognosis of the patients.
