| Research Abstract |
The rupture of gastric varices results in high mortality rate because of larger blood flow. Recently, balloon-occluded retrograde transvenous obliteration (BRTO) has become a standard option for gastric varices in Japan. The technical success of treatment depends on sufficient stagnation of the sclerosing agent in the variceal cavity, but we have sometimes experienced technically difficult cases due to many collateral drainage veins and multiple afferent veins. In this study, we assessed safety and efficacy of B-RTO using coaxial balloon catheter system. The usefulness of temporary occlusion of splenic artery during B-RTO to reduce pressure gradient of variceal cavity was confirmed. Furthermore, we improved double coaxial balloon catheter system. Gastric varices can be treated more effectively and safely using these innovations.
