Abstract

Variations of external jugular vein are common. Here, we present a rare terminal bifurcation of the left external jugular vein. The left external jugular vein was formed by the union of entire retromandibular vein and posterior auricular vein. One inch above the clavicle, it bifurcated into medial and lateral divisions. The medial division terminated into the internal jugular vein and the lateral division terminated into the subclavian vein. Medial division received a common vein formed by the union of anterior jugular vein and an anonymous vein lying under the sternocleidomastoid muscle. The lateral division received a common vein formed by the union of suprascapular and transverse cervical veins. The knowledge about this variation could be useful to head and neck surgeons, radiologists and plastic surgeons.
