2- Lee JG, Park HB, Shin HY et al. Effect of trendelenburg position on right and left internal jugular vein cross-sectional area.
Indeed, the effects of posture on spinal fluid pressure [ 48] and internal jugular vein cross-sectional area [ 48, 49] have been evaluated in healthy subjects, and it has been shown that when humans are upright, the prevailing pressure for both the venous outflow and for the spinal fluid approaches zero at the base of the brain, so negating the idea that a siphon supports CBF.
In this study, the carotid sheath was defined as the ICA, the internal jugular vein, and the areas between them.

In previous investigations (Werner et al, 1999) it could be shown, that transcutaneous readings in the area of the deep jugular lymph node level II IV allow no exact identification of the sentinel nodes.
