[Surgical treatment of renal artery stenosis in children].
Fifty six children with renal artery stenosis (unilateral in 42, bilateral in 14) underwent surgical treatment. Ten nephrectomies and 63 vascular repair procedures were performed. Postoperative follow-up varied from 1 to 14 years. After surgery, blood pressure returned to normal and subsequently remained so in 51 patients without any antihypertensive medication. This represents a 91% success rate. In five patients blood pressure remained high due to lesion of the renal parenchyma. Fibrous dysplasia of the renal artery was the prevailing pathologic findings. In children, associated lesions are especially frequent: coarctation of the abdominal aorta, stenosis, occlusion, aneurysms of the splanchnic arteries, pheochromocytoma. Postoperative prognosis of renovascular hypertension in children is good since atheroma and visceral or renal lesions are usually lacking.
