Structural remodeling of the renal vascular bed during experimental pulmonary stenosis and after its correction.

Renal vessels in pups with experimental pulmonary stenosis, animals with corrected defect, and control dogs were examined by histological and morphometric methods. Pulmonary stenosis was followed by remodeling of the renal vascular bed and adaptive and pathological reconstruction of veins, arteries, and glomeruli. Correction of the defect was followed by regression of pathological changes.
