What is a Superficial Blood Clot? When blood clots in the superficial veins of the leg, it is known as a superficial thrombophlebitis (or commonly, phlebitis). Patients often may experience pain and tenderness on the surface of the leg with appearance of a tender lump or streak. Many times, patients recall a varicose vein in the same area prior to the phlebitis appearing. Varicose veins are a well-recognized risk factor for superficial thrombophlebitis. While phlebitis confined to the surface veins does not pose the same serious risk as DVT, we know that some patients with phlebitis progress to DVT as that surface clot extends to the deep venous system.
A blood clot, also known as deep vein thrombosis (DVT), occurs when blood accumulates or clots in one of the deep veins of the body. According to the Mayo Clinic, blood clots are a serious concern because they can detach themselves from the veins and travel through the bloodstream to the lungs.edness or Warmth. Many patients notice a warm spot near the area where the blood clot has formed. It may feel like a warm sensation or the area may actually feel warm to the touch. In addition, the area may appear red and inflamed.
