Surgical complications of deep brain stimulation (DBS) are comparable to those of other neurosurgical procedures. Serious adverse events occur in 1–2% of patients. Brain hemorrhages can result in permanent neurologic sequelae (eg, aphasia, hemiparesis, and coma) or death. Intracranial hemorrhage occurs in 3.9% of patients. [32] Infection occurs in about 3-5% of patients and may require explantation of the device until the infection is resolved. Seizures are rarely described; postoperative confusion is relatively frequent but usually transient. The risk of surgical complicatoins may be similar between STN DBS and GPi DBS. However, GPi DBS may have a high risk of infection due to more frequent battery replacement.
