Abdominal aortic coarctation, renovascular, hypertension, and neurofibromatosis.

Abdominal aortic coarctation and renal artery stenosis associated with neurofibromatosis is an unusual cause of renovascular hypertension in children and young adults. Sustained hypertension despite pharmacological treatment carries significant end-organ deterioration, failure to thrive, and potentially lethal complications. Timely arterial reconstruction can render these children normotensive, allowing normal development and reducing long-term morbidity. Progression of the arterial occlusive process, however, may occur after surgery. Therefore, careful follow-up is mandatory following aortorenal reconstruction in children with neurofibromatosis.
