The superior mesenteric arteries of twelve dogs were occluded with an inflated balloon on the tip of an endhole catheter while diatrizoate meglumine and diatrizoate sodium (Renografin 76) was injected distal to the occlusion. The balloon was immediately deflated at the end of contrast injection. Films taken over a 33-second period showed consistently excellent visualization of the mesenteric arteries and veins as well as the portal veins. Comparison with studies performed by the conventional, nonocclusion technique confirmed the superiority of the films obtained with the balloon occlusion method. Histologic examination of the mesenteric artery at the site of balloon inflation and of the small and large bowel revealed no abnormalities.
用端孔导管尖端的充气气球阻塞12只狗的肠系膜上动脉，同时在阻塞部位远端注入泛影葡胺和泛影酸钠（76%泛影葡胺）。造影剂注射结束后立即将气球放气。在33秒内拍摄的X线片显示，肠系膜动脉、静脉以及门静脉始终显示极佳。与采用传统非阻塞技术进行的研究相比，证实了气球阻塞法获得的X线片具有优越性。对气球充气部位的肠系膜动脉以及小肠和大肠进行组织学检查，未发现异常。
