Exploration of postural effects on the external jugular and diploic venous system using upright computed tomography scanning

ConclusionCompared to the supine position, the contribution of external jugular tributaries to head venous drainage decreased in the sitting position, whilst most diploic veins maintained their contribution. These results could enhance our understanding of the physiology and pathophysiology of the head region in upright and sitting positions.
