目的 探讨试验性栓塞对造影阴性的动脉性消化道大出血的指征和疗效。资料与方法 对 15 0例消化道大出血患者根据临床表现和内镜检查结果提示行相应动脉造影 ,阴性者 6 4例作试验性栓塞治疗 ,其中胃十二指肠动脉 5 2例 ,胃左动脉 6例 ,直肠上动脉 2例 ,直肠下动脉 4例。栓塞剂采用明胶海绵颗粒及钢圈。结果 栓塞技术成功率为 10 0 %,出血控制率为 5 6 %(36 /6 4)。未见胃肠道缺血坏死等严重并发症发生。结论 动脉造影阴性的消化道大出血根据临床表现和内镜检查结果提示的部位行试验性栓塞可控制部分出血 ,且技术上较安全可行。
Objective To investigate the indications and curative effects of experimental embolization on angiography-negative arterial gastrointestinal hemorrhage. Materials and Methods 150 patients with gastrointestinal bleeding based on clinical manifestations and endoscopic findings prompted the corresponding arterial angiography, the negative were 64 cases of experimental embolization treatment, including gastroduodenal artery in 52 cases, the left gastric artery 6 cases, 2 cases of rectal artery, 4 cases of rectal artery. Embolization agent using gelatin sponge particles and steel ring. Results The success rate of embolization was 100% and the bleeding control rate was 56% (36/64). No serious complications such as gastrointestinal ischemic necrosis occurred. Conclusions Arteriography-negative gastrointestinal hemorrhage is based on clinical manifestations and endoscopic findings prompted by experimental embolization can control part of the bleeding, and technically safer.
