Abstract

We describe the usefulness of n-butyl-cyanoacrylate (nBCA)-assisted retrograde transvenous obliteration (NARTO) for gastric varices in 3 consecutive patients. In all patients, balloon catheters were inserted into the gastrorenal shunt via the left renal vein. After injecting sclerosant into the gastric varix under balloon occlusion, nBCA was injected to the proximal side of the shunt, to completely embolize the shunt. NARTO is a simple technique to achieve stagnation of the injected sclerosant in gastric varices and to occlude a gastrorenal shunt. This procedure is also cost-effective, and may improve procedure time compared with original or modified balloon-occluded retrograde transvenous obliteration.

摘要

我们描述了在3例连续患者中，氰基丙烯酸正丁酯（nBCA）辅助逆行经静脉闭塞（NARTO）对胃静脉曲张的有用性。在所有患者中，通过左肾静脉将球囊导管插入胃肾分流术。在球囊闭塞下将硬化剂注入胃静脉曲张后，nBCA被注射到分流管的近端,完全栓塞分流管.NARTO是一种简单的技术，可以使注射的硬化剂停滞在胃静脉曲张中并阻塞胃肾分流。此程序也具有成本效益，与原始或改良的球囊闭塞逆行静脉闭塞术相比，可以缩短手术时间。
