Blood clots, also known as Deep Venous Thrombosis, or “DVT”, is a common medical problem affecting approximately 1 million people in the US every year. Blood clots can effect the deep veins (DVT) or the superficial veins. DVT have an increased risk of causing complications such as Pulmonary Embolism or Post-Thrombotic Syndrome. Superficial blood clots (superficial thrombophlebitis) are a common problem presenting with linear pain, redness and swelling.
