Vena comitans

Vena comitans is Latin for accompanying vein and is also known as a satellite vein.[1] It refers to a vein that is usually paired, with both veins lying on the sides of an artery. They are found in close proximity to arteries so that the pulsations of the artery aid venous return. Because they are generally found in pairs, they are often referred to by their plural form: venae comitantes.

Anatomical terminology

Venae comitantes are usually found with certain smaller arteries, especially those in the extremities. Larger arteries, on the other hand, generally do not have venae comitantes. They usually have a single, similarly sized vein which is not as intimately associated with the artery.
