Dual microcatheter retrograde transvenous obliteration (DMRTO) of gastric varices enables dual microcatheters to be advanced to the gastric varices themselves or to a site adjacent to the varices. The sclerosing agent is infused through the first microcatheter following coil embolization of the outflow vessels through the second microcatheter, which is placed several centimeters back from the varices. We present two cases of gastric varices in whom balloon-occluded retrograde transvenous obliteration failed, because of angulated gastrosubphrenic shunt in case 1 and a tortuous and elongated gastrorenal shunt in case 2. DMRTO successfully achieved eradication of the gastric varices in both cases.
胃静脉曲张的双微导管逆行静脉闭塞术（DMRTO）可将双微导管推进至胃静脉曲张本身或其附近部位。在通过第二个微导管对流出血管进行弹簧圈栓塞后，通过第一个微导管注入硬化剂，第二个微导管放置在距静脉曲张几厘米远的位置。我们报告了两例胃静脉曲张患者，其中第1例因胃膈下分流成角，第2例因胃肾分流迂曲延长，导致球囊闭塞逆行静脉闭塞术失败。两例患者均通过DMRTO成功消除了胃静脉曲张。
