    Summary

    Peripheral intravenous digital subtraction arteriography offers adequate vessel visualization in 93% of patients. This minimally invasive technique is suitable for various arterial studies, with limitations including cardiac performance and patient cooperation.

    Area of Science:

    • Medical Imaging
    • Vascular Surgery
    • Radiology

    Background:

    • Digital subtraction arteriography (DSA) is crucial for vascular imaging.
    • Peripheral venous injection offers a less invasive alternative to central arterial access.

    Purpose of the Study:

    • To describe a technique for peripheral intravenous digital subtraction arteriography (PIV-DSA).
    • To evaluate the efficacy and limitations of PIV-DSA in a large patient cohort.

    Main Methods:

    • Retrospective review of 504 PIV-DSA studies in 469 patients.
    • Assessment of image quality for anatomical definition of vessels.
    • Analysis of failure rates and causes.

    Main Results:

    • Adequate opacification for vessel definition was achieved in 93% of studies.

  • PIV-DSA was suitable for pulmonary arteries, left ventricle, and systemic arteries.
  • Failure causes included impaired cardiac performance (2.4%) and poor cooperation (1.4%).
  • Angina pectoris led to premature study termination in 1.6% of cases.

    • Conclusions:

    • Peripheral intravenous digital subtraction arteriography is an effective imaging modality.
    • The technique demonstrates high success rates for diverse vascular examinations.
    • Limitations are primarily related to patient's physiological status and cooperation.
