Deep veins of the leg, from Gray's Anatomy

The deep vein is a term used to describe veins that are deep in the body. This contrasts with superficial veins that are close to the body's surface. Deep veins are usually found alongside arteries of the same name, for example, the femoral vein accompanies the femoral artery in the femoral triangle.

Anatomy

Deep veins are typically located within the muscle fascia and accompany corresponding arteries. They play a crucial role in the venous return system, carrying blood back towards the heart. The deep veins in the legs are responsible for the majority of blood return from the lower limbs.

Clinical significance

Deep veins are of particular clinical significance due to the risk of deep vein thrombosis (DVT), a condition where blood clots form in the deep veins of the body, most commonly in the leg. This can lead to serious complications such as pulmonary embolism.
