Feasibility of Magnetoencephalography after endovascular Treatment of ruptured intracranial aneurysms

摘要: Objective: Amongst good outcome survivors of aneurysmal subarachnoid hemorrhage (aSAH), only 23% have normal neurocognitive performance, despite imaging that is often normal. The aim this work to explore the use magnetoencephalography (MEG) after endovascular treatment ruptured aneurysms. Methods: Good aSAH patients treated with coiling and matched controls were recruited. Clinical assessments resting-state MEG anatomical MRI images obtained. Brain space was normalized standard Montreal Neurological Institute (MNI) brain. Areas interest identified Automated Anatomical Labeling (AAL) “virtual electrodes” reconstructed using vector beamformer. Spectral power density estimates for each location averaged across brain derive mean signal power. Virtual-sensor data closest coil assessed quality. Results: Thirteen 13 Mean age 54.5 years (SD=9.9) 56.8 (SD=11.8) aSAH. majority aneurysms (62%) in midline. time from 18.8 months (2.4 67.5; SD=19). Data quality comparable both groups, including virtual-sensors close mass. showed no significant spectral alterations group. Conclusion: Magnetoencephalography feasible treatment. Our results suggest strength presence coils does not interfere testing. Considering common complaints could be developed diagnose, quantify monitor problems
