What is deep vein thrombosis? Deep vein thrombosis (DVT) is a blood clot (thrombus) in a deep vein, usually in the legs. Clots can form in superficial veins and in deep veins. Blood clots with inflammation in superficial veins (called superficial thrombophlebitis or phlebitis) rarely cause serious problems.
