[Neurofibromatosis as a cause of arterial hypertension in children].

Hypertension can complicate the course of neurofibromatosis. When it appears in adulthood (after 18 years of age) it is usually due to pheochromocytoma, but in children the cause is a stenotic lesion of the renal arteries or the suprarenal aorta. Its treatment follows the general principles used in the treatment of the more common forms of renovascular hypertension. We report four patients that developed renovascular hypertension after being diagnosed of neurofibromatosis, they had different localizations of the stenotic lesion, and the diverse types of surgical treatment are analyzed.
