摘　　要：目的：评价ＤＳＡ对不明原因消化道出血的诊断作用。方法：２２例不明原因的消化道出血患者进行ＤＳＡ检查，其中１７例经手术病理证实。结果：１４例ＤＳＡ发现病变，阳性率６３．６％，８例未发现异常。在１４例ＤＳＡ阳性患者中肿瘤６例，血管畸形５例，静脉曲张１例，溃疡１例，多发性息肉１例。８例ＤＳＡ阴性患者６例进行了手术探查，共５例发现病变，其中憩室２例，溃疡、息肉和腺瘤各１例。结合手术情况，在总结１９例阳性病例中有１０例病变位于小肠。结论：小肠疾病是引起不明原因消化道出血的主要原因，其中以肿瘤性病变多见。Objective:To evaluate the value of digital subtraction angiography(DSA)in diagnosis of gastrointestinal bleeding unknown causes.Methods:DSA was performed in 22 patient with gastrointestinal bleeding unknown causes,of which 17 patients were confirmed by surgery and pathology.Results:14 patients(63.6%) were demonstratd to be abnormal on DSA,among them there were 6 cases of tumor,5 cases of vascular malformation,1 case of esophageal varix,1 case of ulcer and 1 case of multiple polypi.6 of 8 patients who weren′t demonstrated to be abnormal on DSA underwent surgical operational exploration and lesions were found in 5 patients(dvertculum 2 cases,ulcer 1 case,polypus 1 case,adenoma 1 case).In combination with DSA and surgical information,it showed that in all of 19 positive patients,the lesions were located in small intestine in 10 cases.Conclusion:Small intestinal disease is main cause of gastrointestinal bleeding unknown causes,of which tumors are common.DSA is a useful method in diagnosis of gastrointestinal bleeding unknown causes.
