A method for assessing the patency of the H-graft interposition mesocaval shunts by computerized tomography is described. Five patients with such shunts were examined with a 5.5 second CT scanner. After locating the graft a 50 cc bolus of 76% diatrizoate was injected into a cubital vein and 3-4 scans were executed at a preselected level. A distinct vessel like enhancement appeared if the shunt was open. With dynamic CT-scanning the flow can be demonstrated in graphical form as time-density curves.
本文描述了一种通过计算机断层扫描评估H型移植脾肾分流术通畅性的方法。使用5.5秒CT扫描仪对5例接受此类分流术的患者进行了检查。在确定移植血管位置后，将50毫升76%泛影葡胺团注注入肘静脉，并在预选层面进行3 - 4次扫描。如果分流术通畅，会出现明显的血管样强化。通过动态CT扫描，血流可以以时间 - 密度曲线的图形形式显示出来。
