Abstract
Purpose
To evaluate the recent topics of Ballloon-occluded retrograde trasnvenous obliteration(B-RTO).
Method
We overviewed the recent scientific papers regarding B-RTO.
Result
B-RTO is a treatment method for occluding varices retrogradely using a sclerosing agent under balloon occlusion of a major draining vein. It has been recognized as an effective treatment method for gastric varices. Hepatic function reserve is improved and liver volume is increased after B-RTO. In recent years, various technical options, such as plug-assisted retrograde transvenous obliteration, coil-assisted retrograde transvenous obliteration, or foam B-RTO, have also been reported. In performing B-RTO, portal hemodynamics must be thoroughly examined radiologically. Judging the classification of the grade of collateral venous hemodynamics is important to select the appropriate embolization technique of B-RTO and to successfully occlude varices. Finally, the word “portosystemic shunt syndrome” has been proposed and the condition should be considered while selecting a treatment for gastric varices.
Conclusion
B-RTO is effective for gastrointestinal varices and portosystemic shunts.
