Transient paradoxical renal vasoconstriction following cardiac operation. Treatment with volume depletion.
Following cardiac operation complicated by inferior myocardial injury, a patient developed normal cardiac output congestive heart failure associated with severe renal vasoconstriction, oliguria and azotemia. The patient's renal dysfunction responded to volume depletion with hemofiltration. These paradoxical renal responses to volume changes may be caused by transiently altered cardiac volume receptor thresholds or afferent signals resulting in cardiorenal dysfunction.
