title: [Intracerebral hemorrhage during multi-track microrecording of deep brain stimulation surgery: a report of three cases].
abstract: We described three cases with hemorrhagic complication during simultaneous multi-track microelectrode recording (MER) for stereotactic implantation of a subthalamic nucleus electrode. Although preoperative planning with gadolinium-enhanced T1-weighted MR images is recommended to prevent the occurrence of intracerebral hemorrhage, it should be noted that the danger from cerebral vasculatures is still underestimated. Multiple nonspecific white matter hyperintensities and asymptomatic lacunar infarcts may be suspected as potential risk factors, so, it is suggested that the number of MER penetrations should be restricted in such cases.
