Overview

CUS stands for Compression Ultrasonography; D-dimer is the highly sensitive assay.

Adapted from ACCP guidelines.

Considerations

• Positive predictive value for compression ultrasonography is 94 percent (95% CI)
• Venography may be used, if noninvasive testing is not clinically feasible.
• A negative D-dimer assay, as a stand-alone test may be insufficient to rule out DVT, in a patient with a high venous thromboembolism probability.
