[Renovascular hypertension in infancy treated by aortorenal by-pass (author's transl)].

The writers record a severe case of renovascular hypertension resulting from fibromuscular dysplasia which appeared in the only main left renal artery. The first clinical symptoms were noticed at five months. The failure of medical treatment led to exploratory surgery at seven months with renal revascularisation by an aortorenal by-pass using a hypogastric arterial autograft. The writers stress the scarcity of hypertension symptoms among infants of less than one year and conclude the impossibility of prognosis in spite of an apparent cure after six months.
