Thrombophlebitis: diagnostic techniques

T D Painter

    Angiology
    |June 1, 1980
    PubMed
    Summary

    Diagnosing deep vein thrombophlebitis (DVT) is challenging as clinical signs are unreliable. Doppler ultrasound and impedance plethysmography show promise for diagnosing proximal DVT.

    Area of Science:

    • Vascular Medicine
    • Diagnostic Imaging
    • Thrombosis Research

    Background:

    • Deep vein thrombophlebitis (DVT) diagnosis relies on often unreliable clinical findings.
    • Pulmonary emboli occur frequently with calf DVT but are typically asymptomatic.
    • Established diagnostic methods like venography are impractical for widespread screening.

    Purpose of the Study:

    • To review the diagnostic literature for deep vein thrombophlebitis (DVT).
    • To evaluate the accuracy and practicality of various DVT diagnostic tests.

    Main Methods:

    • Literature review of diagnostic studies for DVT.
    • Comparison of clinical findings, venography, radioisotope-labeled fibrinogen, Doppler ultrasound, and impedance plethysmography (IPG).

    Main Results:

    • Clinical findings for DVT are unreliable.
    • Venography is accurate but not practical for screening.
    • Radioisotope-labeled fibrinogen is less accurate for proximal DVT.
    • Doppler ultrasound and IPG demonstrate 90% agreement with venography for proximal DVT.

    Conclusions:

    • Accurate diagnosis of DVT remains a clinical challenge.
    • Doppler ultrasound and IPG are effective, practical tools for diagnosing proximal DVT.
    • Further research may refine non-invasive diagnostic strategies for DVT.
