摘　　要：目的评估经导管动脉美蓝造影在下消化道动脉出血定位中的临床应用价值。方法 10例下消化道动脉出血患者行介入腹腔动脉造影,发现出血责任动脉后,将微导管超选置于出血责任动脉内,在外科术中经微导管注入美蓝注射液显示出血段肠管,为切除出血段肠管提供精准定位。结果 经导管动脉美蓝造影可清晰显示出血段肠管,10例患者的出血段肠管得到快速精准切除治疗,术后患者消化道出血停止,且无手术相关并发症发生。结论 经导管动脉美蓝造影可精准发现下消化道动脉出血段肠管,为外科手术快速切除出血段肠管提供精准定位,值得临床广泛推广应用。Objective To evaluate the clinical application value of transcatheter arterial methylene blue angiography in the localization of lower gastrointestinal arterial bleeding.Methods Ten patients with lower gastrointestinal arterial bleeding received interventional celiac artery angiography.After the bleeding responsible arteries were identified,a microcatheter was super-selectively placed in the bleeding responsible artery.During surgical procedure,the methylene blue solution was injected through the microcatheter to display the bleeding segment of the intestinal tract,providing precise localization of the bleeding intestinal segment for surgical resection.Results Transcatheter arterial methylene blue angiography could clearly display the bleeding segment of the intestinal tract.The bleeding segments of the intestinal tract in the 10 patients were quickly and accurately removed.After surgery,the gastrointestinal bleeding stopped,and no surgery-related complications occurred.Conclusion Transcatheter arterial methylene blue angiography can accurately detect the arterial bleeding segment of the lower gastrointestinal tract,which provides precise localization for quickly removing the bleeding segment of intestinal tract,therefor,this technique is worthy of widespread clinical application.
