Dr. Rakesh Wahi, director of research at the Center for Vascular Medicine in Greenbelt, Maryland, also serves as consultant to the Loyola University Thrombosis Research Group. Rakesh Wahi, MD, has also published articles on deep vein thrombosis in such publications as Clinical and Applied Thrombosis/Hemostasis.
A serious and potentially life-threatening condition, deep vein thrombosis occurs when a blood clot forms in a vein located deep within the body. Clots in these veins are particularly dangerous because they can easily break away from their sources and travel through the bloodstream to the lungs. There, they can lead to a blockage of blood flow known as a pulmonary embolism.
Deep vein thrombosis is most common in the veins of the calf and thigh. They most often occur when the patient is inactive for a long period of time, whether due to medical incapacity or a forced and prolonged sedentary period such as a long plane flight. Patients most often notice a deep vein thrombosis when it causes the leg to become achy, tender, or swollen. The affected leg may also feel tender to the touch or exhibit redness, though smaller clots may be asymptomatic and only present a problem after they travel to the lungs and cause embolism.
