A new technique--transvenous serial Xero-arteriography (TSXA)--was evaluated in order to avoid the risks of the commonly used angiographic methods in av-fistulas. The contrast medium is injected intravenously in the contralateral forearm, an average of 5 per cent of the total contrast medium appearing in the arm to be examined. The Xerox-system now allows visualisation of both arteries and fistulated veins. Using a cassette-changer morphologic and functional alterations can be examined. TSXA is largely free of risk, avoiding arterial access and patient discomfort. TSXA gives reliable information about the real haemodynamic situation of av-fistulas including morphologic and functional alterations. Thus, surgical procedures can be performed more precisely, more carefully and time-saving.
为避免动静脉瘘常用血管造影方法的风险，对一种新技术——经静脉连续干板动脉造影术（TSXA）进行了评估。将造影剂静脉注射到对侧前臂，平均有5%的总造影剂出现在待检查的手臂中。现在的干板系统能够显示动脉和瘘管化静脉。使用换片暗盒可以检查形态学和功能改变。TSXA基本无风险，避免了动脉穿刺和患者不适。TSXA能提供有关动静脉瘘真实血流动力学情况的可靠信息，包括形态学和功能改变。因此，手术操作可以更精确、更仔细且更节省时间地进行。
