Thirty days complication rate following surgery performed for deep-brain-stimulation

Serious adverse events (SAEs) during the first 30 postoperative days after stereotactic surgery for Deep-Brain-Stimulation performed in 1,183 patients were retrospectively collected from five German stereotactic centers. The mortality rate was 0.4% and causes for death were pneumonia, pulmonary embolism, hepatopathy, and a case of complicated multiple sclerosis. The permanent surgical morbidity rate was 1%. The most frequently observed SAEs were intracranial hemorrhage (2.2%) and pneumonia (0.6%). Skin infection occurred in 5 of 1,183 patients (0.4%). Surgical complications caused secondary AEs (e.g. pneumonia) preferentially in older patients and in patients treated for Parkinson's disease (PD). Complication rates did not differ among the five centers. © 2007 Movement Disorder Society
