Intraoperative monitoring of brain-stem auditory evoked potentials.
Brain-stem auditory evoked potentials (BAEP) were monitored during 545 neurosurgical operations in the cerebellopontine angle. The BAEP were irreversibly obliterated in five patients who required deliberate section of the auditory nerve. Technical difficulties interfered with monitoring in three cases, and three patients had deafness and absent BAEP preoperatively. Reversible alterations in BAE...
متن کامل[Intraoperative monitoring of somatosensory evoked potentials].
Somatosensory evoked potentials (SEPs) were monitored during 20 operations, 13 for tumors in the posterior fossa and upper cervical region and seven for the treatment of aneurysms or carotid cavernous fistulae. Monitoring was technically satisfactory in 16 patients (80%). In two patients, monitoring was compromised by contamination with electrical noise. Two patients with mass le sions i...
متن کاملIntraoperative Monitoring of Motor-Evoked Potentials for Supratentorial Tumor Surgery
OBJECTIVE The purpose of this study was to assess the feasibility and clinical efficacy of motor evoked potential (MEP) monitoring for supratentorial tumor surgery. METHODS Between 2010 and 2012, to prevent postoperative motor deterioration, MEP recording after transcranial stimulation was performed in 84 patients with supratentorial brain tumors (45 males, 39 females; age range, 24-80 years;...
متن کاملA New Measure for Monitoring Intraoperative Somatosensory Evoked Potentials
OBJECTIVE To propose a new measure for effective monitoring of intraoperative somatosensory evoked potentials (SEP) and to validate the feasibility of this measure for evoked potentials (EP) and single trials with a retrospective data analysis study. METHODS The proposed new measure (hereafter, a slope-measure) was defined as the relative slope of the amplitude and latency at each EP peak com...
متن کاملClinical Utility and Limitations of Intraoperative Monitoring of Visual Evoked Potentials
OBJECTIVES During surgeries that put the visual pathway at risk of injury, continuous monitoring of the visual function is desirable. However, the intraoperative monitoring of the visual evoked potential (VEP) is not yet widely used. We evaluate here the clinical utility of intraoperative VEP monitoring. METHODS We analyzed retrospectively 46 consecutive surgeries in 2011-2013. High luminance...
