Gastrointestinal bleeding arterial intervention

He angiography, in order to save time and avoid missing for bleeding artery. The 8 patients were positive for the first time, contrast angiography was found bleeding artery or blood vessel disease, for the treatment of earned time. Arterial bleeding in the imaging of the most reliable signs for the contrast agent to leak out,Oakley Sunglasses, when the bleeding I-> 0.5ml / s when the DSA can --716-- Contemporary Medicine January 2009 Volume 15 l2 35 Interventional Radiology in China Topics December 2009 Volume 3, No. 6 Figure 1DSA intestinal adenoma showed tumor vessels and swollen bleeding diverticulum Figure 2DSA tumors showed staining of small intestine, and no contrast medium extravasation of blood appear, but with the resulting intestinal gas and bowel movements artifact identification. 3.1 The position of the catheter embolization in the branch of the celiac artery, collateral circulation due to their respective organs rich line catheter can reach the target artery embolization, but are likely to form collateral blood vessels should each embolization, to prevent the re-issue of blood. The 5 cases of bleeding in the abdominal artery branch artery embolization were made, results were satisfactory. For the mesenteric artery branch. Shown by Figure 3DSA anastomosis gastroduodenal artery blood supply to their respective single organ, and its collateral branches in its distal aortic arch and the walls of vascular network, improper embolism likely to cause intestinal segmental necrosis. Liu Jin Xin, proved more than three bowel artery branches exist,mbt schuhe, when the chosen site of embolization straight artery, aortic arch arteries and the last stage is a safe and hemostatic effect is good. When the embolization site selection in the terminal aortic arch artery, then there is likely to lead to intestinal infarction. Therefore the small intestine must be micro-catheter embolization, and must be plugged into the last stage aortic arch or beyond before the first branch can be when the embolization. The group l patients with small intestinal bleeding in patients with adenomas, we micro-catheter aortic arch through the terminal directly to the tumor anterior edge of the bolt into the small amount of ultra-lipiodol emulsion and gelatin sponge liquid particles, the effect is very good, no complaints were not specific and may independent of tumor blood supply related. 3.2 The choice of embolic agents embolic material is currently more commonly used gelatin sponge, stainless steel ring, PVA, ethanol, etc., for gastrointestinal bleeding,polo outlet online, the liquid embolic agent should be prohibited, concrete should be based on Arterial bleeding and lesions to decide. The 8 patients, in addition to l cases of superior mesenteric artery collateral due to the existence of stainless steel ring as a safer use of gelatin sponge particles. 3.3 Application of pituitrin difficult for superselective catheterization or angiography negative patients, reduced vascular perfusion hemostasis better. Catheter operation as close as possible bleeding site, such as can not find the bleeding point, put the catheter placed in the estimated blood loss based on clinical manifestations of vascular artery most likely the beginning part, the use of slow syringe pump infusion of vasopressin 8 ~ 16U, 30 minutes after the review of contrast, significantly reduced if the blood vessels, blood flow distal small vessels can enter, stop infusion. Gastrointestinal bleeding reported in the literature should be the first to use perfusion of vasoconstrictor substance to stop bleeding '; infusion treatment hemostatic effect in the short term hemostatic rate was 82.7%, 54.5% long-term efficiency. Although we are up to stop the bleeding in 3 cases the purpose, but the case of too little, yet not jump on. Gastrointestinal bleeding artery interventional therapy has been widely used in clinical practice,radii shoes, accurate and selective angiography can be found in time and site of arterial bleeding, the bleeding artery embolization or vasopressin infusion can rapidly and effectively and safely to achieve hemostasis purposes. Huazhong University of Science obtained in this paper, Union Hospital, Tongji Medical College Professor Zheng Chuansheng guidance and modified to express my sincere thanks!
