| Abstract |
|
PRA in peripheral vein, both renal veins and both inferior vena cava (JVC) both proximal and distal to the drainage of the both renal veins was measured in 80 normotensive children with no renal disease undergoing routine cardiac catheterization due to congenital heart disease which did not cause significant hemodynamic changes in most of them. And we presented the results as reference values/ranges of PRA in children. 1) PRA did not differ significantly between both renal veins at any absolute PRA levels with, a mean ratio (RT/LT) of 0.97±0.18. 2)The mean PRA ratio of one renal vein with higher PRA level to the contralateral renal vein with lower PRA level (R/RC) was 1.165, and the 95% confidence limit was 1.0 to 1.463. 3)The mean PRA ratio of the contralateral renal vein to the distal IVC(RC/D) was 1.22, and the 95% confidence limit was 0.51 to 1.93. 4)The PRA in peripheral veins showed rough but significant inverse relationships with both age and body surface area.
