Clinical features of renovascular hypertension in infancy: report of a 9-month-old infant.

Certain common but seldom recognized clinical features of renovascular hypertension peculiar to infancy are emphasized in this communication from the observations made in a 9-month-old infant. Failure to thrive, extreme irritability, hypotonia, anorexia, vomiting, diarrhea, respiratory distress, and congestive heart failure are common clinical findings. Unless the physician is aware of this symptomatology or blood pressure is routinely obtained in all infants, the condition is likely to be missed. Renovascular hypertension is malignant and carries a high mortality but if diagnosed early may be cured by surgical intervention.
