Figure 1. Representative ultrasound images of the right carotid artery (top) and right (R) and left (L) prefrontal-to-frontal (Fp1-F3) electroencephalographic (EEG) waveforms (bottom) obtained shortly before (A) and after (B) release of the second tourniquet. After deflation of the second tourniquet (B, top), multiple intravascular emboli (E) were observed in the carotid artery (CA) but not in the internal jugular vein (IJ). Release of the second tourniquet was also associated with marked bilateral slowing and reduction of fast EEG activity (B, bottom) as compared to the EEG activity before tourniquet deflation (A, bottom).
