Hemolysis following correction of double-outlet right ventricle
A Singh, EA Letsky and J Stark
A 41/2-year-old child developed a severe degree of intravascular hemolysis
within 24 hours after intraventricular correction of double- outlet right
ventricle with a Dacron patch. The child developed jaundice, with a serum
bilirubin of 4.3 mg. per cent. The hematocrit value fell from 47 to 25 per
cent and the reticulocyte count rose to 22 per cent. The hemolysis
diminished after 3 weeks and completely disappeared after 6 weeks. We
presume that the hemolysis was due to turbulence caused by a long, curved
patch and that its disappearance coincided with the endothelialization of
the patch. The child is well 3 years after the operation.
