Patients have traditionally been diagnosed as having DVT whenever thrombosis could be identified, irrespective of its extent or location. The diagnosis was usually established by venography, and anticoagulant treatment was then instituted. In recent years, the diagnosisVT has increasingly been made by noninvasive methods, many of which are relatively insensitive to minor forms of the disease, partiparticularlylarlys and calf vein thrombopthrombophlebitis. these newer diagnostic methods, the term "DVT" does not reflect all patientsthrombosis of the calf veins, which may not be diagnosed by the method employed.
Whether or not failure to detect such early forms of DVT is clinically important been a matter of considerable debate. Life-endangering embolism is due to mechanical obstructionight side of the heart, almost invariably due to large clots originating in the iliac, femoral, or popliteal veins. Thrombi in these locations are accurately detected
