Abstract:
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.(J Intervent Radiol,2023,32:1230-1232)
