説明

We constructed an anatomical snuff box type or an anterior arm type (namely, Brescia Cimino type) arteriovenous fistulae in two groups of 10 patients with chronic renal failure, respectively, and compared these two types in terms of pre and post arteriovenous anastomosis blood flows using an ultrasound duplex system composed of a doppler flowmeter and B-mode colour scanner. 1. The mean major diameter of the radial artery was significantly smaller in the anatomical snuff box type than in the anterior arm type. However, the mean major diameter of the cephalic vein immediately after arteriovenous anastomosis was not significantly different between the two types. 2. The mean blood flow volume of the radial artery was lower, and that of the ulnar artery was higher in the anatomical snuff box type than in the anterior arm type. There were no differences between the two types in the mean blood flow volumes of the brachial artery and cephalic vein. 3. The increasing volumes of the ulnar artery, from the pre-operative value, and the ratio of this volume to the sum of the increasing blood flow volumes of radial and ulnar artery, from pre-operative values, were higher in the anatomical snuff box type than in the anterior arm type.<br>It was concluded that the blood flow from the radial artery to the shunt was lower in the anatomical snuff box type than in the anterior arm type, but that the blood flow from the ulnar artery to the shunt was higher in the former than in the latter. Thus, there was no difference in the shunt flow volume between these two types of arteriovenous fistulae.
