FEW Adverse Effects with DBS By Alex Morrisson SYDNEY, Australia -- June 21, 2013-- Treatment of movement disorders with deep brain stimulation (DBS) can be accomplished with few adverse events, researchers said here at the 17th International Congress on Parkinson’s Disease and Movement Disorders. In a retrospective analysis of 94 patients who underwent 128 procedures, researchers said there were no complications in 84 patients. There was 1 infection, 1 intracranial haemorrhage that resolved without sequela, 1 lead malfunction, 2 lead migrations, and 5 cases of transient delirium, said Padmaja Vittal, MD, Tulane University Health Sciences Center and Ochsner Medical Foundation, New Orleans, Louisiana. In procedures performed from 2008 to 2010, the infection rate was 1.06% among the 94 patients and was 0.78% for all 128 procedures. Lead migration was 2.12%. The researchers scrutinised the medical charts of patients at the centre who had undergone DBS at the centre and looked for any infections or any complications. “We excluded patients who had the procedure performed at other institutions and came to us for replacement of leads or things like that,” said Dr. Vittal. “Our study only reviewed the patients who were treated by our neurosurgeon.” “The majority of our patients reported that they achieved improved symptom control after undergoing the procedure,” he said. More than 96% of patients treated self-reported improvement in their movement disorder symptoms, she reported. In the study, 70 patients (58 men, 12 women) were treated for symptoms of Parkinson’s disease and 22 patients were treated for symptoms of essential tremor. Three patients were treated for other movement disorders. “Systematic analysis of surgical data from different movement disorder centres will help us share information regarding techniques, outcomes, and complications,” said Dr. Vittal.
