Deep vein thrombosis (DVT)

Deep vein thrombosis occurs with the lack of movement of blood, resulting in a clot (thrombus) within a deep vein. Deep vein thrombosis may or may not have symptoms such as pain and swelling. Deep vein thrombosis is a serious condition because a clot (thrombus) can break off easily by movement since the veins are lodged deep within muscle. When a clot breaks free of the vein wall it is characterized as an embolus. The embolus can travel to the heart or lungs causing what is known as a pulmonary embolism (PE).

What causes the formation of DVT?

Some people have predisposing conditions affecting the coagulation rates of their blood. The three main causes of DVT are trauma, lack of movement, or hyper coagulation conditions. Factors that increase the risk of DVT include trauma, congestive heart failure, obesity, smoking and venous insufficiency. Each patient seen at Medical Vein Clinic is screened for deep vein thrombosis (DVT) by duplex ultrasound interrogation.
