    Summary

    Digital subtraction angiography (DSA) via intravenous injection is useful for studying the aorta, especially in hypertensive patients and renal transplants. However, the arterial route remains necessary for certain applications, like assessing arterial angioplasty outcomes.

    Area of Science:

    • Medical imaging
    • Vascular radiology

    Background:

    • Digital subtraction angiography (DSA) is a key imaging modality for evaluating the aorta and its branches.
    • Intravenous DSA is commonly employed for hypertensive patients and renal transplant assessments.
    • Limitations of intravenous injection necessitate alternative approaches in specific clinical scenarios.

    Purpose of the Study:

    • To highlight the utility of Digital subtraction angiography (DSA) in vascular imaging.
    • To discuss the indications and limitations of intravenous versus arterial routes in DSA.
    • To emphasize the importance of the arterial approach for specific vascular interventions.

    Main Methods:

    • Review of Digital subtraction angiography (DSA) techniques.
    • Comparison of intravenous and arterial contrast injection methods.
    • Case examples illustrating DSA applications in hypertensive patients, renal transplants, and post-angioplasty evaluations.

    Main Results:

    • Intravenous DSA provides valuable insights into aortic and renal vasculature.
    • Arterial DSA is essential for detailed assessment of immediate post-intervention results, such as arterial angioplasty.
    • The choice of injection route depends on the specific clinical question and anatomical region.

    Conclusions:

    • Digital subtraction angiography (DSA) is a versatile tool for vascular imaging.
    • While intravenous injection is suitable for many applications, the arterial route offers distinct advantages for specific diagnostic and interventional scenarios.
    • Optimizing DSA technique, including the route of contrast administration, is crucial for effective patient management.
