    Summary

    Digital subtraction angiography (DSA) phlebography is a safe and effective method for diagnosing deep venous system disorders in the lower extremities. This study found it useful for identifying deep vein thrombosis and venous wall irregularities.

    Area of Science:

    • Vascular Imaging
    • Radiology
    • Venous Diagnostics

    Background:

    • Deep venous system disorders are a significant clinical concern.
    • Accurate diagnostic methods are crucial for effective patient management.

    Purpose of the Study:

    • To evaluate the safety and utility of digital subtraction angiography (DSA) phlebography for diagnosing lower extremity deep venous system disorders.

    Main Methods:

    • DSA phlebography was performed on 36 legs in 21 patients using a supine position and a dilute contrast medium.
    • Vein opacification and abnormal findings were assessed.

    Main Results:

    • Posterior tibial and peroneal veins showed high identification rates (94.7% and 97.4%).
    • Deep vein thrombosis was detected in 5 legs, reflux in 14, and venous wall irregularity in 16.

  • Anterior tibial vein opacification was suboptimal (63.2%), potentially due to tourniquet compression.

    • Conclusions:

    • DSA phlebography is a safe, comfortable, and useful diagnostic tool for deep venous system disorders.
    • It effectively identifies deep vein thrombosis, reflux, and venous wall irregularities.
