Does a combined diagnostic approach using Doppler ultrasound and impedance outflow testing improve diagnostic accuracy in patients with suspected venous thromboembolism?
A combined noninvasive diagnostic approach significantly improves the accuracy of detecting venous thromboembolism and safely identifies patients who do not require treatment.
James S.T. Yao (1974) conducted an observational in Venous thromboembolism (n=162). Combined diagnostic approach (Doppler ultrasound and impedance outflow testing) vs. Independent use of diagnostic techniques was evaluated on Diagnostic accuracy. A combined diagnostic approach using Doppler ultrasound and impedance outflow testing increased diagnostic accuracy for venous thromboembolism to 95%, compared to 82.9% and 70.9% independently.
