[Hypertension and multiple renal arteries. Comparative studies on the frequency of multiple renal arteries in hypertensive patients and normotensives].

The frequency of multiple renal arteries in 394 aortographies was found to be 29.2%. The results were then grouped according to the indication for the investigation and according to the recorded blood pressure readings into a hypertensive and a normotensive group. Comparison of these two groups showed no significant difference in the frequency of multiple renal arteries. There were also no significant differences comparing double and multiple arterial supply of one kidney or one-sided or double occurrence of multiple renal arteries.
