    This study established a formula to determine normal pulmonary vein diameter in children using height. The findings provide a practical method for assessing venous size in pediatric cardiology.

    Area of Science:

    • Pediatric Cardiology
    • Anatomy
    • Medical Imaging

    Background:

    • Accurate measurement of pulmonary veins is crucial for diagnosing and managing various pediatric cardiac conditions.
    • Existing data on normal pulmonary vein dimensions in children is limited, hindering precise clinical assessment.

    Purpose of the Study:

    • To establish a normative reference for pulmonary vein diameter in children.
    • To correlate pulmonary vein diameter with anthropometric parameters for a predictive formula.

    Main Methods:

    • Autopsy examination of 24 normal children's hearts and great vessels.
    • Measurement of pulmonary vein diameters.
    • Multivariate regression analysis correlating diameters with height, body surface area, weight, and age.

    Main Results:

    • Pulmonary vein diameter showed the strongest correlation with patient height.
    • A regression formula was derived: normal pulmonary vein diameter (mm) = 0.07 × height (cm).

    Conclusions:

    • Height is the most reliable predictor of normal pulmonary vein diameter in children.
    • The derived formula offers a practical tool for estimating normal pulmonary venous dimensions in pediatric clinical practice.
