[Abnormalities of the renal arteries in arterial hypertension in adults]

Results of arterial surveys on the basis of renal arteriograms in 100 consecutive unselected and hospitalized cases of lone arterial hypertension of the adult. Abnormal polar arteries with direct branching from the aorta were observed in 52 cases, combined with a stenosing or parnechymatous arterial anomaly in 7, quite isolated in 45 cases (61.8 percent of 73 cases). The very great incidence of abnormal polar arteries is a fundamental epidemiological datum of lone arterial hypertension of the adult.
