Overview
Initial test in these patients should be a compression ultrasound if a previous ultrasound is available for comparison. A highly-sensitive D-dimer is also a possible initial test. If the compression ultrasound results are abnormal but non-diagnostic (increase in residual venous diameter of < 4 but ≥ 2 mm), further testing with venography or CT venography may be indicated. Patients suspected to have a recurrent episode of DVT may benefit from thrombophilia evaluation.
