目的：探讨介入诊断和治疗对急性消化道出血的应用及其价值。方法：急性消化道出血病例34例，常规在腹腔动脉和肠系膜上、下动脉插管造影并作出出血的定位和定性诊断。造影后停留导管持续灌注垂体后叶素，或行栓塞治疗，追踪手术病理结果和观察止血情况。结果：定位和定性诊断的准确率为100％。23例行灌注，11例行栓塞治疗。33例在介入治疗后止血，1例死亡。结论：动脉造影是急性消化道出血最直观又最准确的诊断方法，介入灌注血管加压素和栓塞治疗安全有效，可作为外科手术的补充疗法。“,”Purpose: To discuss the usage and value of trans-catheter diagnosis and treatment in acutehemorrhage of digestive tract. Methods: 34 patients with acute hemorrhage of digestive tract were perfomed catheterizations from celiac arteries, superior and inferior mesenteric arteries to locate and realize thebleeding sites through angiography. 23 patients were treated by arterial infusion of hypophamine, and theother 11 treated by embolization with gel foam or coils. Results: The accuracy of angiograghic diagnosis foracute hemorrhage of digestive tract reached to 100 %. 33 patients bleeding were ceased after treatments, 1patients died of shock. Conclusion: Arterial angiography is the most precious diagnostic method for acutehemorrhage of digestive tract. Trans-catheter infusion and embolization are safe and effective.
