目的:探讨DSA成像技术在消化道出血诊疗中的应用。方法:选择合适的数字减影血管造影(DSA)技术参数,对55例消化道出血患者行腹腔动脉、肠系膜上动脉、肠系膜下动脉数字减影血管造影检查,根据情况对部分患者行超选择性DSA检查。结果:55例中,31例获得满意的DSA检查效果,出血部位和原因诊断清楚,通过介入治疗成功地达到了止血目的;24例未能明确诊断消化道出血。结论:良好的DSA成像质量是消化道出血诊断与治疗的保证。
Objective: To investigate the application of DSA in the diagnosis and treatment of gastrointestinal bleeding. Methods: The appropriate parameters of digital subtraction angiography (DSA) were selected and 55 cases of gastrointestinal bleeding were examined by digital subtraction angiography of the celiac artery, superior mesenteric artery and inferior mesenteric artery. According to the situation, some patients underwent superselective DSA check. Results: Among the 55 cases, 31 cases achieved satisfactory results of DSA examination. The bleeding site and cause were clearly diagnosed. The purpose of hemostasis was successfully achieved by interventional therapy. No diagnosis of gastrointestinal bleeding was confirmed in 24 cases. Conclusion: Good DSA imaging quality is the guarantee of diagnosis and treatment of gastrointestinal bleeding.
