Area of Science:

  • Vascular Medicine
  • Diagnostic Imaging

Background:

  • Acute deep venous thrombosis (DVT) is a significant vascular condition.
  • Identifying risk factors for thrombi formation is crucial for patient management.

Purpose of the Study:

  • To evaluate the diagnostic accuracy of duplex ultrasonography and Doppler examination in identifying acute deep venous thrombosis.
  • To identify factors influencing discrepancies between duplex and Doppler findings.

Main Methods:

  • Duplex ultrasonography was used to identify acute deep venous thrombosis in 127 extremities across 96 patients.
  • Doppler examination was performed concurrently, and results were compared with duplex findings.

Main Results:

  • Duplex ultrasonography identified acute deep venous thrombosis in 127 extremities.

Related Experiment Videos

  • Doppler examination correlated with duplex results in 61% of cases (77 extremities).
  • Discrepancies were noted, particularly with proximal and occlusive thrombi, and Doppler's accuracy was insufficient for guiding anticoagulation decisions.

    • Conclusions:

    • Duplex ultrasonography is effective in diagnosing acute deep venous thrombosis.
    • Doppler examination has limitations in accuracy for deep venous thrombosis diagnosis, especially in lower extremities, impacting treatment decisions.
