Portal veins The general rule is that arteries from the heart branch out into capillaries, which collect into veins leading back to the heart.

Sclerotherapy can also be performed using foamed sclerosants under ultrasound guidance to treat larger varicose veins, including the great saphenous and small saphenous veins.
