[Hypertension secondary to intrarenal aneurysms in childhood].

OBJECTIVES

Arterial hypertension due to renovascular dysfunction is uncommon in children. The most common cause is stenosis of the renal artery and, rarely, aneurysm of secondary arteries. The present case underscores the therapeutic difficulties. Treatment must be based on the clinical symptoms, location, size, number and etiology of these vascular malformations.

METHOD/RESULTS: We describe a 4-year-old patient with secondary arterial hypertension arising from several aneurysms in the primary and secondary arterial branches of the right kidney that had been diagnosed by arteriography. After medical treatment had failed, the patient underwent a right nephrectomy since local or conservative procedures could not be done.

CONCLUSIONS

It is widely advocated in the literature that patients with medically refractory arterial hypertension warrant surgical treatment. The type of surgery will depend on the location and the characteristics of the lesion.
