Unexpected median somatosensory evoked potentials (SEPs) fluctuations during brain cavernous malformation resection with no post-operative deficit
Authors' conclusion
During brain cavernous malformation resection, significant fluctuations in the amplitude of different components of m-SEPs may occur. These changes may be due to excitability variations on m-SEP generators and do not translate into new post-operative neurological deficits.
Study context
- Population
- Patients undergoing cavernous malformation resection near the sensory-motor cortex, preoperative seizures only
- Participants
- 3 patients
- Outcome
- Intraoperative m-SEP changes and post-operative deficits
Main finding
As reported in the abstract
Two patients presented permanent changes in the cortical potentials
2
None of these patients developed new post-operative clinical deficits
0
Observational data: associations, not effects.
