目的：评价DSA与X线电影摄影对消化道出血检查的敏感性。材料与方法：50例病人，其中急性消化道出血24例，慢性消化道出血26例，全部病例均行腹腔动脉，肠系膜上、下动脉造影，必要时加做胃左动脉、胃十二指肠动脉、肝动脉造影。其中7例行栓塞治疗。栓塞剂为明胶海绵颗粒或不锈钢圈。结果：阳性发现38例（38／50），其中20例可见造影剂从血管内外溢，7例栓塞治疗后即刻止血。10例同时先后使用了DSA和Cine，7例栓塞病人选用DSA。DSA提示可疑出血或失败者均采用X线电影摄影。结论：DSA检查适用于易配合及栓塞治疗的病例．具有快速实时成像及分辨率高；X线电影适用于不易配合及显示细微病变者，不受病人运动及肠蠕动影响，图像清晰。
Objective: To evaluate the sensitivity of DSA and X-ray photography to gastrointestinal bleeding examination. Materials and Methods: 50 patients, including 24 cases of acute gastrointestinal bleeding, chronic gastrointestinal bleeding in 26 cases, all cases underwent celiac artery, superior mesenteric artery angiography, if necessary, plus gastric left artery, gastroduodenal Arterial and hepatic arteriography. Seven of them received embolization. Embolization agent is gelatin sponge particles or stainless steel ring. Results: 38 cases (38/50) were found positive, of which 20 cases showed the intravascular excretion of contrast medium, and 7 cases stopped bleeding immediately after embolization. DSA and Cine were used in 10 cases and DSA in 7 cases. DSA prompt suspicious bleeding or losers are using X-ray photography. Conclusion: DSA examination is suitable for the case of easy cooperation and embolization. With fast real-time imaging and high resolution; X-ray film is not suitable for patients with minor lesions and display, from the patient’s movement and bowel movements, the image is clear.
