[Multiple vascular stenoses in neurofibromatosis (author's transl)].

Vascular lesions due to neurofibromatosis have been predominantly reported in the renal arteries as cause of arterial hypertension, but they can occur everywhere. The angiography shows a smoothly bordered stenosis at the origin of the artery with an elongated funnel shaped poststenotic deformity. Collateral vessels are often present. Reconstructive arterial surgery is in a high percentage successful. The main differential diagnosis includes fibromuscular dysplasia. Arterial hypertension in a young person with neurofibromatosis should suggest the presence of pheochromocytoma or renovascular disease.
