目的 分析DSA检查及栓塞治疗在 临床诊断和治疗急性消化道大出血的效 果。方法 本次研究的对象是随机选取了 2014年6月-2015年6月我院收治的30例消 化道出血的患者，进行腹腔动脉、肠系 膜上下动脉造影，对可能出血的部位进行 选择性插管造影，其中17例患者明确诊断 并行栓塞治疗。结果 30例患者中20例造 影阳性(66.7%)，10例阴性(33.3%)。18例 接受了栓塞治疗，16例出血停止，一个月 内无复发出血；1例栓塞后次日死亡；1例 栓塞三天后复发出血，进行外科手术后痊 愈。结论 DSA检查对急性消化道大出血具 有较好的诊断价值，栓塞介入治疗对消化 道出血止血效果优良，值得临床深入研 究。

Objective To analyze the clinical effect of DSA and embolization therapy in acute gastrointestinal hemorrhage. Methods The study object, 30 cases with gastrointestinal bleeding, were randomly selected from June 2014 to June 2015 in our hospital, all of them had celiac artery and mesenteric angiography, and have selective catheterization to the possible bleeding sites, including 17 patients with definite diagnosis who had embolization. Results Twenty cases of angiography in 30 patients were positive (66.7%) and 10 (33.3%) were negative. 18 cases underwent embolization, and 16 cases stopped bleeding after embolization, with no recurrence of bleeding for a month. One case died the next day after embolization, one case had the recurrence of bleeding after three days of embolism, but recovered after surgery. Conclusion DSA examination has good diagnostic value of acute digestive tract hemorrhage. The hemostatic effect of embolization in interventional therapy for gastrointestinal bleeding is good and worthy of clinical research.
