[Digital angiography of the renal arteries by an intravenous route. A simplified technic].
Of the 1,000 patients addressed to us for intravenous digital angiography (IVDA) of the renal arteries for arterial hypertension, for control of the artery of a transplanted kidney or for preoperative check-up prior to transplantation of a kidney, 738 were examined by a simplified technique. Compared to the standard practice this method simply consists of a manual injection of a standard ionic contrast medium via an antecubital vein punctured with a large catheter needle (caliber 14 G), without preparatory injection of an intestinal antispasmodic. This method has produced a satisfactory arterial opacification in 96% of the cases. The advantages and disadvantages of the technique are discussed. Of the 262 remaining patients, 250 were also examined by the peripheral venous mode, but the technique had to be modified in at least one of its aspects for one reason or another. Only 12 patients were not examined by the peripheral venous mode (7 puncture failures, 4 permanent venous accesses already installed). The IVDA simplified technique appears to be reliable for detecting reno-vascular arterial hypertension and with certain limitations, for the control of kidney grafts. With regard to the preoperative check-up before kidney transplantation, IVDA still does not seem a suitable replacement for the traditional method of angiography.
