    Digital subtraction angiography (DSA) offers superior visualization of upper-extremity veins compared to conventional methods. DSA reduces iodine use and examination time, enhancing patient comfort for evaluating venous thrombosis.

    Area of Science:

    • Radiology
    • Vascular Imaging
    • Diagnostic Angiography

    Background:

    • Evaluating upper-extremity vein patency is crucial for diagnosing conditions like venous thrombosis.
    • Conventional angiography has limitations in visualization and patient experience.

    Purpose of the Study:

    • To compare the efficacy of digital subtraction angiography (DSA) with conventional angiography for upper-extremity venography.
    • To assess DSA's impact on imaging quality, contrast dose, examination time, and patient comfort.

    Main Methods:

    • Digital subtraction angiography (DSA) and conventional venography were utilized.
    • The study focused on evaluating the patency of upper-extremity veins, including innominate veins and the superior vena cava.

    Main Results:

    Related Experiment Videos

    • Venous thrombosis was readily diagnosed with both methods.
    • DSA provided enhanced visualization of the innominate veins and superior vena cava.
    • DSA required one-third the iodine concentration and reduced examination time by 50% compared to conventional venography.
    • Patients reported greater comfort and acceptance with DSA.

    Conclusions:

    • Digital subtraction angiography (DSA) is a superior imaging technique for evaluating upper-extremity veins.
    • DSA offers significant advantages in terms of image quality, efficiency, and patient tolerance in cooperative patients.
