title: [Arterial hypertension in children].
abstract: It is considered hypertension in children, the persistent increase of the blood pressure values above percentile 95 for age and sex, in no less than three determinations, with adequate register techniques. Blood pressure is maintained mainly by the regulation of metabolism of sodium and water in the intravascular space, through the adequate balance of intake, filtration, reabsorption and renal throughout. It is also regulated by hormonal factors. Weight gain control in teen-agers could be useful to prevent high blood pressure in adults. In children, it is generally secondary to renal, reno-vascular, endocrinological or tumoral diseases. Clinical manifestations and the recommended diagnostic procedures are analysed to detect the most frequent causes of hypertension at different ages. Most cases response with antihypertensive drugs in combination with hyposodic diet. For the hypertensive crisis, asa diuretics and powerful antihypertensive drugs may be employed. Patients with chronic renal insufficiency could also need dialytic treatments. Renovascular diseases require almost always invasive treatments. Better prognosis in children with severe high blood pressure is related with recent diagnostic procedures, surgical techniques and antihypertensive drugs improvements.
