    Digital subtraction angiography (DSA) is a valuable diagnostic tool for pediatric patients, offering high accuracy with minimal radiation exposure. This study highlights its effectiveness in diagnosing various conditions in children, particularly intracranial diseases.

    Area of Science:

    • Pediatric Radiology
    • Vascular Imaging
    • Diagnostic Angiography

    Background:

    • Intravenous digital subtraction angiography (DSA) in pediatric populations is not widely established.
    • Despite limited experience, DSA shows promise due to its ease of use, low complication rates, and diagnostic accuracy.

    Purpose of the Study:

    • To evaluate the utility and diagnostic yield of intravenous DSA in infants and children.
    • To assess the feasibility of DSA in pediatric patients, addressing potential challenges like patient movement and radiation exposure.

    Main Methods:

    • Conducted 87 DSA examinations on 74 pediatric patients.
    • Employed sedation and meticulous technique to minimize patient movement and vessel overlap.
    • Utilized a low-radiation dose system (2-38 mR/frame).

    Main Results:

    • Achieved sufficient diagnostic detail in most examinations.
    • Demonstrated wide applicability across multiple organ systems.
    • Found DSA particularly useful for intracranial diseases and preoperative evaluation of neoplasms.

    Conclusions:

    • Intravenous DSA is a safe and effective imaging modality for pediatric patients.
    • DSA's diagnostic accuracy and low complication rate support its broader use in pediatric radiology.
    • Further studies are needed to define specific indications for DSA in children.
