Altered renovascular resistance after spontaneous recovery from XXXX .

@entity1 @entity8 @entity137 @entity1494 @entity294 @entity11849 @entity1381
Twenty-three @entity1 were evaluated from 1-15 (mean 6) years after recovering from an episode of @entity294 -associated associated childhood @entity1381 (DA- @entity11849 ). All @entity1 had received only conservative treatment; none had been given experimental, anti-coagulant, or immunological therapies. Follow-up studies included morphologic and duplex Doppler sonograms. Doppler sonography was used to determine the resistive index, a measure of renovascular resistance. Histories and physical examinations revealed no abnormalities. Results of laboratory studies, which included calculated glomerular filtration rates, were all within normal limits, except for one @entity1 with minor @entity1494 . Renal sonograms showed no significant @entity8 or parenchymal appearance. However, Doppler sonographic examinations revealed that the DA- @entity11849 @entity1 demonstrated less of a decrease in renovascular resistance with age than did the control group (p < 0.0002). After recovery, @entity1 treated exclusively with conservative management during an acute episode of DA- @entity11849 appeared to have an excellent long-term prognosis. Comparison of our results with those from other studies in which investigational therapies have been used during the acute phase of DA- @entity11849 suggests that latent @entity137 which cause long term sequelae may not have been appreciated previously. The clinical significance of the altered renal vascular resistance remains to be delineated.
