Application Value of DSA in the Bleeding of Small Bowel Angiodysplasia

目的 探讨DSA对小肠血管发育不良的应用价值 ,提高对小肠不明原因出血诊断的准确性。方法 肠系膜上动脉选择性插管DSA检查 ,结合手术病理所见 ,对 9例小肠血管发育不良出血者的DSA表现进行分析研究。结果 确诊为出血性毛细血管扩张病 5例 ,表现为节段性肠管小血管增多密集、浓染 ,伴造影剂外溢。动静脉畸形 4例 ,表现为粗大的供血动脉和连接扭曲成团的畸形血管巢 ,以及粗大的引流静脉。结论 DSA检查对小肠不明原因出血的诊断有着不可替代的作用 ,尤其对血管性病变 ,更是主要的检查手段。
