The American College of Radiology Appropriateness Criteria Committee on interventional radiology has recently recognized balloon-occluded retrograde transvenous obliteration (BRTO) as a viable alternative to transjugular intrahepatic portosystemic shunt (TIPS) in certain anatomic and clinical scenarios for the management of gastric varices. However, it did not define these particular scenarios where BRTO would be a viable alternative. With the increased practice of BRTO in the United States, a debate ensues in the United States and Europe whether BRTO or TIPS should be the primary endovascular procedure of choice for gastric varices. From a conservative standpoint, BRTO is reserved for patients who are not TIPS candidates, while other institutions leave the decision to operator preference and "favorable anatomy" for either procedure. To add to the debate, there is a heightened interest in the improved efficacy of variceal embolization (metallic/bland embolization) concurrent with TIPS compared with TIPS without embolization, and a recent article describing a combination of TIPS and BRTO that demonstrated impressive results superior to BRTO or TIPS alone. This article discusses the most recent outcomes of TIPS and embolization of gastric varices as well as combining BRTO and TIPS.
美国放射学会介入放射学适用性标准委员会最近认识到,在某些解剖学和临床情况下,对于胃静脉曲张的治疗,球囊闭塞逆行经静脉闭塞术(BRTO)是经颈静脉肝内门体分流术(TIPS)的一种可行替代方案。然而,该委员会并未明确BRTO成为可行替代方案的具体情形。随着BRTO在美国应用的增加,美国和欧洲引发了一场关于BRTO和TIPS究竟哪一个应作为胃静脉曲张首选血管内治疗方法的争论。从保守的角度来看,BRTO适用于不适合TIPS的患者,而其他机构则将选择留给操作者的偏好以及两种手术中“有利的解剖结构”。更添争论的是,相较于未进行栓塞的TIPS,人们对TIPS联合静脉曲张栓塞术(金属/单纯栓塞)疗效的提升兴趣浓厚,并且最近有一篇文章描述了TIPS和BRTO联合应用,结果令人印象深刻,优于单独的BRTO或TIPS。本文讨论了TIPS和胃静脉曲张栓塞术的最新成果,以及BRTO与TIPS联合应用的情况。
