Vena comitans is Latin for accompanying vein. 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. Venae comitantes are usually found with certain smaller arteries especially those in the extremities.
