    Summary

    Intraarterial digital subtraction angiography (DSA) enhances vascular procedures by improving image quality and reducing contrast, time, and discomfort. This technique offers significant benefits for embolotherapy and angioplasty patients.

    Area of Science:

    • Vascular imaging
    • Interventional radiology

    Background:

    • Intraarterial digital subtraction angiography (DSA) is a key imaging modality.
    • Its application as an adjunct to vascular interventions is under investigation.

    Purpose of the Study:

    • To evaluate the utility of intraarterial DSA in interventional vascular procedures.
    • To assess the impact of intraarterial DSA on procedure efficiency and patient experience.

    Main Methods:

    • Intraarterial digital subtraction angiography (DSA) was employed in 56 patients undergoing embolotherapy or transluminal angioplasty.
    • DSA served as an adjunct to guide and monitor the interventional procedures.

    Main Results:

    • Intraarterial DSA demonstrated improved contrast resolution and immediate image availability.
