RESUMEN
Considering that there's a lack of information concerning the risks of radiation exposure in pregnancy, the author identifies such risks and estimates its magnitude. He underlines the fact that radiological examinations deliver lower doses in relation to those that can be proved to be malefic to the embryo, both in the somatic and genetic plan.

In the 59 hypertensive patients submitted to percutaneous transluminal angioplasty (PTA) of the renal artery, there was an immediate success in the blood pressure in 91.5% and a later one of 79.6%. In these patients we obtained better results: 81.4% in the unilateral lesions, more than in the bilateral ones--72.7%; 82.5% in the renal artery trunk lesions, more than in the ostium ones--71.4%; 88.9% in the lesions of fibromuscular origin, more than in the aterosclerotic ones--75%; 84.4% in up to 55 years old patients, more than in older ones--71.4%. These differences were not significant. The results of renal angioplasty in renovascular hypertension suggest this type of intervention as an alternative treatment.
