DVT (Blood Clot in the Leg)
Phlebitis in the deep veins
Deep venous thrombosis (DVT) refers to a blood clot embedded in one of the major deep veins of the lower legs, thighs, or pelvis. A clot blocks blood circulation through these veins, which carry blood from the lower body back to the heart. The blockage can cause acute pain, swelling, or warmth in the affected leg. Blood clots in the veins can cause inflammation (irritation) called thrombophlebitis.
