    Summary

    Descending venography is an effective diagnostic tool for saphenofemoral venous valvular incompetence. This method accurately evaluates chronic venous insufficiency, aiding surgical correction and postoperative assessment.

    Area of Science:

    • Vascular Surgery
    • Diagnostic Imaging
    • Venous Physiology

    Background:

    • Surgical techniques for lower extremity venous insufficiency have increased focus on venous valvular function.
    • Chronic venous insufficiency (CVI) affects a significant patient population, impacting quality of life.

    Purpose of the Study:

    • To evaluate the diagnostic accuracy of descending venography for venous valvular incompetence.
    • To compare descending venography with bidirectional Doppler ultrasound and ascending venography in patients with CVI.

    Main Methods:

    • A comparative study involving 32 patients with clinical signs of CVI.
    • Utilized descending venography, bidirectional Doppler ultrasound, and ascending venography.
    • Postoperative assessment included descending venography and Doppler ultrasound in 12 surgically treated patients.

    Main Results:

    • Descending venography demonstrated high effectiveness and accuracy in diagnosing venous valvular incompetence.
    • The technique specifically proved reliable for the saphenofemoral venous system.
    • Comparison with Doppler ultrasound and ascending venography supported its diagnostic value.

    Conclusions:

    • Descending venography is a valuable and accurate method for assessing saphenofemoral venous valvular incompetence.
    • This imaging modality is crucial for the preoperative evaluation and postoperative monitoring of patients undergoing correction for CVI.
    • The findings support the integration of descending venography in the diagnostic pathway for complex venous disorders.
