A Detailed Analysis of Equivocal Duplex Findings in Patients With Suspected Deep Venous Thrombosis

Abstract

Even if a duplex examination is equivocal, it is still possible to extract clinically useful information by categorizing the duplex results into subgroups with low, intermediate, and high probability of deep venous thrombosis. This can have implications for the diagnostic or therapeutic handling of these patients and thus can increase the utility of sonography in patients with inconclusive duplex findings.
