不明原因下消化道出血的血管造影及导管治疗

目的：明确下消化道出血原因及止血治疗。材料与方法：对21例不明原因下消化造出血病人行选择性血管造影，并经导管灌注垂体后叶素、明胶海绵条栓塞。结果：血管造影诊断阳性率为76％，16例病人治疗后均止血。结论：血管造影是诊断不明原因下消化道出血的首选方法，垂体后叶素灌注短期（1周）止血效果显著，但易复发，栓塞治疗更重要的在于确定病变部位以利手术。

Arterial Angiography and Treatment of Lower Alimentary Tract Hemorrhage without Definite Cause

To identify the cause of hemorrhage and to stop the bleeding. Materials and Methods: Se-lective angiography was used in 21 patients of lower alimentary tract hemorrhage without definite cause. Pi-tuitrin infusion and gelfoam embolization were performed through the catheter. Results: The positiue rate of diagnosis by angiography is 76% and all bleeding stopped in 16 patients. Conclusion: Angiography was the first choice for the diagnosis of lower alimentary tract hemmorrhang without definite cause. Pitutrin infusion through the catheter stop the bleeding well in a short time (one week or so) but reocurrence frequently.The significance of edbolization was to define the site of bleeding and to make the operation easy.
