【摘要】 目的探讨急性消化道出血的动脉造影表现和栓塞治疗的疗效及临床价值。方法23例急性消化道出血患者分别行腹腔动脉、肠系膜上动脉和肠系膜下动脉造影,对其中造影明确诊断12例进行超选择插管并行栓塞治疗,栓塞材料分别为明胶海绵颗粒、明胶海绵颗粒+弹簧圈、聚乙烯醇微粒。结果23例中15例出现阳性征象,主要表现为对比剂外溢、动脉瘤、肿瘤血管和染色、动脉侵蚀、局部血管痉挛等,12例接受了栓塞治疗,其中10例出血停止,30d内无再出血,无肠缺血、肠坏死等并发症,1例栓塞后次日死于多器官功能衰竭,1例栓塞3d后复发出血,经外科手术治疗痊愈。结论动脉造影及栓塞治疗是急性消化道出血安全有效的诊断和治疗方法。更多还原

【Abstract】 Objective To evaluate the manifestation of arterial angiography and effect of intra-arterial embolization on the diagnosis and therapy of acute gastrointestinal tract bleeding.Methods Selective arterial angiography of celiac trunk,superior mesenteric artery and inferior mesenteric artery was performed on 23 cases of acute gastrointestinal tract bleeding.Intra-arterial embolization was performed in 12 cases with positive findings.The embolizing materials were gelfoam particles,gelfoam with coils and polyvinyl alcohol particle.Results 15 of 23 cases were presented with positive findings.The findings under angiography included contrast extravasation, aneurysm,neovascularization or tumorous stain,arterial invasion and local vascular spasm,etc.12 of the positive cases underwent intraarteial embolization.The bleeding was stopped in 10 cases without re-bleeding within 30 days,without intestinal ischemia or intestinal necrosis.One case died of multiple organ failure on the next day after embolization.Re-bleeding occurred in one case three days later and was cured after surgical intervention.Conclusion The application of angiography and intra-arterial embolization is safe and effective in diagnosis and therapy for acute gastrointestinal tract bleeding.更多还原
