A method of renal arteriography with insertion of a combination of two vascular catheters via the deep femoral artery into the abdominal aorta.
One of the catheters was used for injection of the contrast medium and another was equipped with a balloon to obstruct the blood flow to the lower extremities.
In this paper the method was introduced with a report of the results.
1) In this method, the quantity of the contrast medium required for visualization of the artery was found to be from 15-20cc. Both sides of the renal artery were visualized as clearly as a selective angiography. Other large arteries such as the lienal, hepatica communis, gastroduodenalis, superior or inferior mesenterica arteries were not so clearly visualized.
2) Clear visualization of the renal artery was made, when the distance from the balloon to the tip of the injection catheter was about 5cm.
3) In this method, the density of arteriogram and nephrogram of both sides was found to be about equal.
The III-IV degree of difinition was found in 96.8 per cent of arterograms taken in this series, whereas in the existing method it was 57.1 per cent.
4) As the complication of this method, a case of thrombosis and 4 cases of hematoma were experienced in this series, but renal failure or the changes of serum electrolytes was not encountered.
