Neonatal renal arterial embolism syndrome.
Attention is called to a poorly recognized syndrome of neonatal renal arterial embolism, presumably from the ductus arteriosum, resulting in malignant hypertension, congestive heart failure, respiratory distress, and increased renin secretion. Radiographic studies revealed a ductus diverticulum and multiple narrowed arteries including the lower pole branches of the right renal artery. Renal scan showed poor imaging of the lower pole of the right kidney. Nephrectomy resulted in a prompt return of the blood pressure into the normal range. Eight cases recorded in the literature resemble the one reported here, and six of the eight had an associated thrombosis of the ductus arteriosum. Our patient appears to be the first case recognized by modern techniques followed by nephrectomy and clinical cure.
