Indicación de estimulación cerebral profunda en casos complejos de enfermedad de Parkinson. Experiencia en el Hospital Clínico Universidad de Chile

Introduction: Deep brain stimulation (DBS) is a standard surgical procedure for the treatment of advanced Parkinson Disease (PD) with motor complications that cannot be adequately managed by medical treatment. Currently available literature can guide physicians on basic aspects of patients’ selection and indications for DBS. However, there is a range of real-world clinical settings where the indications of DBS for Parkinson disease are debatable. Objective: to present the experience on PD patients with complex clinical manifestations treated with DBS in our hospital. Method: Report of four PD cases treated with DBS. Case 1: 63-year old woman with advanced PD and severe motor complications; Case 2: 60-year old man with 5 years of disease duration and mild motor complications; Case 3: 67-year old man with severe ventriculomegaly that may have precluded direct electrode passage to the surgical target; Case 4: 67- year-old woman with putative severe axial disability. Results: After one year of follow-up, all patients showed improvement on motor symptoms as well as quality of life. Discussion: We provide a brief rationale for the patient selection in each case to support the decision-making in the management of PD patients with complex clinical cases.
