Balloon-occluded retrograde transvenous obliteration of gastric varices by a microcatheter insertion method was performed in eight patients with large collateral veins or a large gastrorenal shunt. A 3-F microcatheter was selectively inserted into the gastric varices through a 6-F balloon catheter wedged in the left adrenal vein. Selective venography of the gastric varices and injection of the sclerosing agent, a mixture of 10% ethanolamine oleate and iopamidol, through the microcatheter system without occluding the collateral veins was accomplished in one treatment session in all patients. There have been no complications or recurrences of gastric varices in any of the patients during the follow-up period.
对8例伴有粗大侧支静脉或巨大胃肾分流的患者，采用微导管插入法行经皮球囊闭塞逆行静脉内胃静脉曲张闭塞术。通过楔入左肾上腺静脉的6F球囊导管，将3F微导管选择性插入胃静脉曲张内。在不闭塞侧支静脉的情况下，通过微导管系统对胃静脉曲张进行选择性静脉造影，并注射硬化剂（10%油酸乙醇胺和碘帕醇的混合物），所有患者均在一次治疗中完成。随访期间，所有患者均未出现胃静脉曲张的并发症或复发。
