Variables of interest included demographics, underlying diagnoses, and the presence of a Doppler\u2010confirmed median artery. Ultrasonographic examinations were performed on both upper extremities by a single investigator. Patient\u2010 and limb\u2010level analyses were performed. A multivariable generalized logistic regression analysis was used to test the association between the prevalence of limb\u2010specific persistent median arteries and age.

The patient\u2010specific prevalence rate (persistent median arteries present in 1 or both limbs) was 26.7%. Among these patients (n\u2009=\u200936), a persistent median artery was present bilaterally in 55.6% (n\u2009=\u200920). The limb\u2010specific prevalence rate (proportion of limbs with a persistent median artery) was 20.7%. After adjusting for race, for every 1\u2010year increase in age, the odds of a persistent median artery decreased by 4.4%. After adjusting for age, African Americans were significantly more likely to present with a persistent median artery (odds ratio, 3.78; 95% confidence interval, 1.25\u201311.48).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Ultrasonography can effectively visualize anatomic variants, such as persistent median arteries, in the pediatric population.
