急性肠道缺血需紧急诊断和治疗以防肠道最终梗死和坏死。对早期肠道缺血的临床估计可能错误,即使诊断早有怀疑,因需用侵入性影像技术如动脉造影致使确诊延迟。近年来发展用放射性核素技术诊断和定位心肌急性缺血或梗死。本文是应用相同的非侵入性闪烁图技术以期解决急性肠道缺血的诊断问题。方法:用65只3～5 kg兔作研究,在硫贲妥钠20mg/kg静脉诱导全麻下作腹部正中切口。其中5只兔假性手术后作非缺血性对照,其余60只兔分3组,每组20只。为使20～30 cm的末端回肠缺血,一组阻断游离的肠系膜静脉,一组阻断游离的肠系膜动脉,阻断方法是结扎肠系膜上动脉或静脉主要分枝并结扎
Acute intestinal ischemia is urgently diagnosed and treated to prevent the final intestinal infarction and necrosis. Clinical estimates of early GI may be wrong, even if the diagnosis is already suspected, due to the need for invasive imaging techniques such as angiography to delay the diagnosis. In recent years, the development of radionuclide technology to diagnose and locate acute myocardial ischemia or infarction. This article is the application of the same noninvasive scintigraphy technique to address the diagnosis of acute intestinal ischemia. Methods: A total of 65 rabbits weighing 3 to 5 kg were used in this study. The median abdominal incision was made under general anesthesia with 20 mg / kg thiopental sodium. Five of the rabbits were non-ischemic after pseudo-surgery, and the other 60 rabbits were divided into 3 groups of 20 rats each. One group blocks free mesenteric veins, one group blocks free mesenteric arteries, in order to cause ischemia in the terminal ileum of 20-30 cm. The blocking method is to ligate the main branch of the superior mesenteric artery or vein and ligate
