    Summary

    Ultrasound phlebography effectively detects early circulatory failure by assessing abdominal vein changes. This method is valuable for diagnosing circulatory issues in the greater circulation, especially when examining the inferior vena cava and liver veins.

    Area of Science:

    • Vascular Medicine
    • Diagnostic Imaging

    Background:

    • Circulatory failure poses significant diagnostic challenges.
    • Early detection is crucial for effective management of circulatory conditions.

    Purpose of the Study:

    • To evaluate ultrasound phlebography for assessing abdominal vein parameters in circulatory failure.
    • To determine the diagnostic utility of ultrasound phlebography for different venous systems.

    Main Methods:

    • Ultrasound phlebography was performed on 67 patients with circulatory failure and 40 healthy individuals.
    • Linear parameters of abdominal veins were analyzed, including changes during respiratory tests in horizontal and vertical positions.

    Main Results:

    • A correlation was observed between the severity of circulatory failure and reduced respiratory variations in major venous vessels.
    • Ultrasound phlebography of the inferior vena cava and hepatic veins identified early-stage circulatory failure.
    • Portal vein examination was informative only in late-stage circulatory failure.

    Conclusions:

    • Ultrasound phlebography is a valuable tool for early diagnosis of circulatory failure in the greater circulation.
    • The technique's effectiveness varies depending on the specific venous system examined, with inferior vena cava and liver veins being most informative early on.
