【摘要】 目的：通过血管造影对１８ 例“不明原因”慢性肠道出血（ＣＩＢＵＣ） 的诊断，结合术后病检，评价其应用价值。方法：对我院１８ 例“不明原因”慢性肠道出血患者，通过肠系膜上、下动脉造影诊断，并经手术及病理证实，与小肠灌肠、内窥镜检查进行比较。结果：１８ 例病例小肠灌肠、内窥镜检查均无明确诊断或可疑阳性诊断，血管造影示肿瘤性病变１４ 例、非特异性溃疡１ 例，血管畸形３ 例。结论：小肠灌肠、内窥镜检查，不易显示病变和血管畸形以及容易漏诊之小肠引起的消化道出血，而血管造影有较高的诊断率更多还原

【Abstract】 Purpose: To evaluate the diagnostic value of angiography for chronic intestinal bleeding of unknown origin Methods: Superior and inferior mesenteric arteriography were performed in 18 cases of chronic intestinal bleeding with unknown origin followed by surgical operation Results: The 18 cases of this series either failed barium enema examination or endoscopy with negative or dubious findings comprised 14 cases of neoplasms, 1 non-specific ulcer and 3 vascular malformation and all were diagnosed by angiography Conclusion: Angiography is of high diagnostic value in patients with chronic intestinal bleeding of unknown origin更多还原
