- Abstract
Purpose: To measure common femoral artery (CFA) diameters in infants and children referred for cardiac catheterization and investigate if CFA diameters can be predicted upon the basis of age, body mass index (BMI), and height., Methods: CFA diameters were measured in 84 infants and children (50 boys; age range 1- 220 months) referred for diagnostic or therapeutic cardiac interventions. Sonographic measurements were made in a supine position utilizing a 7.5-MHz linear transducer; diameters were defined as the intima to intima distance. Age was described in months and height in centimeters. The Spearman correlation coefficient (rho) was used to test the similarity of diameters between sides; the Pearson correlation coefficient (r) was used to analyze the influence of age, height, and BMI on CFA diameter., Results: Diameters of the right and left CFA were similar (rho=0.951). Age and height were highly correlated (rho=0.956), but not BMI and height (rho=0.279). The best model was CFA diameter = -0.838 + 0.031 height + 0.046 BMI. Height was the most relevant determinant for CFA diameter (p<0.0001, 90% CI 0.027 to 0.036; BMI: p=0.093, 90% CI 0.001 to 0.090, and the intercept: p=0.032, 90% CI-1.475 to-0.200)., Conclusions: Common femoral artery diameter can be sufficiently predicted from height and BMI of infants and children prior to femoral catheterization or surgical reconstruction.
