Combined modality ultrasound (compression ultrasound with either Doppler or color Doppler) is the initial test of choice for suspected<unk><unk>  deep vein thrombosis (UEDVT).  If the initial ultrasound is negative and the clinical suspicion is still high, further testing with serial ultrasound, D-dimer, or venography should be performed.  Anticoagulation therapy with either low molecular weight heparin or fondaparinux is the preferred initial treatment for UEDVT over intravenous or subcutaneous unfractionated heparin. If the UEDVT is associated with a central venous catheter, the duration of anticoagulation therapy is 3 months if the central venous catheter is removed, or as long as the central venous catheter is present in case it was not removed.
