Baseline Amplitude Ratios of Median Nerve Somatosensory Evoked Potentials: Clinical Implications During Carotid Endarterectomy
Authors' conclusion
In CEA patients, a decreased IAR reflects the acuity of an infarction or injury but does not predict clamp-induced ischemia. Contralateral carotid artery occlusion showed a trend toward predicting clamp-induced ischemia.
Study context
- Population
- Patients after carotid endarterectomy (CEA) with mSSEP monitoring, 2015–2019228 for clamp-ischaemia predictors
- Participants
- 221 patients
- Exposure
- Ipsi-to-contralateral mSSEP baseline amplitude ratio (IAR) across symptom/infarction (S/I) subgroups vs +S/+Ia
- Outcome
- Mean IAR by S/I subgroup
