Posterior external jugular vein

The posterior external jugular vein (or the vein of Kocher) is usually described as the superficial vein of the neck that arises in the occipital region and has various termination sites. It may be a tributary not only of the external jugular vein, but it can alternatively flow into the common facial vein, internal jugular vein, jugular venous arch, or even directly into the brachiocephalic vein. However, we will review this vein as a tributary of the external jugular vein.
