| Abstract |
|
PRA’s in peripheral vein, both renal veins, and inferior vena cava (IVC) were measured in 25
normotensive children without renal disease undergoing cardiac catheterization for their underlying
cyanotic congenital heart disease. And we presented the results as reference values/ranges of PRA in
children.
1) There was no significant difference in PRA between both side renal veins at any absolute PRA
levels with a mean ratio (RT/LT) of 0.97±0.22.
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 1.19, and the 95% confidence limit was 1.0 to 1.59. And 3 children(12%)
showed a ratio higher than 1.5 with a highest value of 1.68.
3) The increase in hematocrit correlated linearly with the increase in peripheral vein PRA, with a
coefficient of correlation of 0.67 (p< 0.005).
In conclusion, a more prudent judgment for the meaning of measured PRA’s should be needed in
children with severe polycythemia. |
