What is "angular vein"

n. a short vein formed by the supraorbital vein and the supratrochlear vein and continuing as the facial vein [syn: vena angularis]

The angular vein is the upper most segment of the facial vein, above its junction with the superior labial vein. It is formed by the junction of the supratrochlear vein and supraorbital vein, runs obliquely downward by the side of the nose, passes under zygomaticus major and joins with the superior labial vein.

The angular vein is linked with the cavernous sinus by the superior and inferior ophthalmic veins which are devoid of valves. It receives the lateral nasal veins from the ala of the nose, and the inferior palpebral vein.
