    Area of Science:

    • Vascular Medicine
    • Lymphatic System Research

    Background:

    • Lymphatic hypoplasia is a potential, yet understudied, cause of lymphedema.
    • Understanding the prevalence of lymphatic abnormalities in the general population is crucial for diagnosing primary lymphedema.

    Purpose of the Study:

    • To determine the prevalence of lymphatic hypoplasia in the lower limbs of adults without clinically apparent lymphedema.
    • To investigate potential differences in prevalence between males and females.

    Main Methods:

    • A prospective study design was employed.
    • 744 adult patients without lymphedema were assessed for lymph vessel abnormalities in their lower limbs.

    Main Results:

    • Lymphatic hypoplasia was identified in 7 patients, yielding a prevalence of 0.94% (95% CI: 0.24-1.64%).

  • Prevalence was slightly higher in males (1.1%) than females (0.5%), though not statistically significant.

    • Conclusions:

    • The prevalence of lymphatic hypoplasia in asymptomatic individuals is higher than previously estimated for primary lower limb lymphedema.
    • Lymphatic hypoplasia is likely one contributing factor among others in the development of clinical lymphedema.
