[Effectiveness of roentgeno-endovascular dilatation in the treatment of renovascular hypertension].

The techniques and methodology of roentgeno-endovascular dilatation, used as part of the treatment for renovascular hypertension in 50 patients with 66 arterial stenoses of varying etiology, are described. The factors that may affect the efficacy of the procedure are discussed: the duration and etiology of the disease, stenosis localization, the number of affected renal arteries, plasma renin activity in renal veins, the dilating catheter used, etc. The stenosed portion of an artery could not be passed in 4 patients. In 38 (82.6%) of 46 patients, whose stenosed renal arterial segments were successfully passed and roentgeno-endovascular dilatation was attempted, systemic arterial BP eventually returned to normal or diminished.
