    Summary
    This summary is machine-generated.

    Percutaneous transpopliteal venography offers a novel method to assess lower extremity deep venous valve function. This technique accurately evaluates valve competence, identifying primary valvular incompetence even when superficial valves remain functional.

    Area of Science:

    • Vascular Surgery
    • Diagnostic Imaging
    • Venous Physiology

    Background:

    • Ascending and descending venography have limitations in fully assessing deep venous valve function.
    • Evaluating the competence of lower extremity deep venous valves is crucial for diagnosing venous insufficiency.

    Purpose of the Study:

    • To introduce and evaluate percutaneous transpopliteal venography as a new diagnostic method.
    • To assess the function and competence of deep venous valves in the lower extremity.

    Main Methods:

    • Percutaneous puncture of the popliteal vein in the popliteal fossa.
    • Cephalad insertion of a catheter for venographic study of venous valves.
    • Visualization of the ilio-femoropopliteal vein and individual valve competence testing.

    Main Results:

    • The ilio-femoropopliteal vein was clearly visualized.
    • Accurate, one-by-one testing of valve competence was achieved.
    • Identified cases where distal femoral and popliteal valves were incompetent despite competent superficial femoral vein valves.

    Conclusions:

    • Percutaneous transpopliteal venography effectively overcomes limitations of traditional venography.
    • This method accurately diagnoses primary valvular incompetence of deep veins in the lower extremity.
    • It highlights the importance of evaluating distal valve function in the deep venous system.
