title: Transient renal artery stenosis in infants: myth or reality?
abstract: We describe two infants with bilateral renal artery stenoses and severe hypertension. Adequate control of blood pressure was achieved by medical management. Endoluminal balloon dilatation of the renal arteries had been deferred because of their small size. On follow-up it was noticed that blood pressure had become progressively easier to control, with lesser amounts of antihypertensive medication. In fact, medication could be completely discontinued and blood pressure remained normal. On repeat arteriogram, bilateral renal artery stenoses had almost resolved in both patients. The etiology of the stenoses was not established in these patients. However, regardless of etiology, the transient nature of hypertension and renal artery stenoses in these two cases demonstrates that patient medical management of hypertension in infants can be a valid therapeutic option and occasionally obviate the need for unnecessary risky procedures.
