Set feasibility of routine SEP monitoring in emergent internal carotid artery (ICA) recanalization.
05/2013 to 02/2015 were performed 12 emergent ICA recanalisations after acute ischaemic stroke (AIS). Mean age 72.7; ICA occlusion: 6 (50%), 90-99% stenosis: 6 (50%).
Inclusion criteria: AIS or crescendo TIA < 24 hours, ICA occlusion or stenosis, functional independence before stroke.
Exclusion criteria: hemorhagic stroke, ischaemia on CT scan.
Median SEP were monitored during carotid surgery.
Clinical finding was evaluated 3 months after surgery.
N20/P25 amplitude was decreased in 5 (41.7%) at symptomatic side (in 1 by > 50%) comparing to asymptomatic.
Successful recanalisation: 11 (91.7%), intraluminal shunt was placed in 1 according SEP amplitude decrease intraoperatively.
Mean muscle strength: arm: 2.4, leg: 3.3, speech disorder: 8 (66.7%).
3 month outcome: muscle strength: 3.9, 4.4 respectively, speech disorder: 3 (25.0%). Modified Rankin Score 0-1: 8 (66.7%), mRS 2: 3 (25.0%), mRS 6: 1 (8.3%).
Median SEP is feasible to monitor in emergent ICA recanalizations.
Median SEP amplitude seems to be promising marker of good clinical outcome.
