Effect of Head Rotation on Jugular Vein Patency Under General Anesthesia. The Canadian journal of neurological sciences. Le journal canadien des sciences neurologiques Burbridge, M. A., Min, J. G., Jaffe, R. A. 2019: 1–3

Abstract

Head rotation causes compression and occlusion of the ipsilateral internal jugular (IJ) vein. This can result in raised intracranial pressure and increased bleeding if the patient is having or has recently had surgery. The amount of head rotation in adults resulting in occlusion of the ipsilateral IJ vein is unknown however. We measured the amount of head turn that produced occlusion of the ipsilateral IJ vein in 25 patients having surgery under general anesthesia. On average, 80% of IJ veins occlude at a mean of 55.6° on the left and 53.3° on the right.
