摘　　要：目的探究多层螺旋CT血管造影(CT angiography,CTA)在急性肠梗阻患者中的应用及诊断价值。方法选取急性肠梗阻患者90例为研究对象,经手术证实机械性肠梗阻34例、动力性肠梗阻29例、血运性肠梗阻27例,均给予X线平片、CT平扫、CTA检查,以外科手术结果作为“金标准”,分析X线平片、CT平扫、CTA检查的诊断效能。结果3种诊断方式对不同肠梗阻病因检出率,差异有统计学意义(P<0.05);CTA检查机械性肠梗阻和急性血运性肠梗阻检出率高于X线平片,差异有统计学意义(P<0.05),CT平扫、CTA诊断急性肠梗阻的敏感度、特异度、准确度高于X线平片;CTA诊断急性肠梗阻的敏感度、特异度、准确度高于CT平扫,差异有统计学意义(P<0.05)。结论通过CTA诊断急性肠梗阻疾病检出率较高,诊断效能良好,具有极高临床推广价值。Objective To explore the application and diagnostic value of multi-slice spiral CT angiography(CTA)in patients with acute intestinal obstruction(AIO).Methods A total of 90 patients with AIO were selected as the research subjects,including 34 cases of mechanical intestinal obstruction,29 cases of dynamic intestinal obstruction and 27 cases of hemovascular intestinal obstruction confirmed by operation.All patients were given X-ray plain film,CT plain scan and CTA examination,and surgical results were taken as the“gold standard”to analyze the diagnostic efficacy of X-ray plain film,CT plain scan and CTA examination.Results There was statistical significance in the detection rate of different causes of intestinal obstruction by the three diagnostic methods(P<0.05).The detection rate of mechanical intestinal obstruction and acute blood-transporting intestinal obstruction by CTA was higher than that by X-ray plain film,and the difference was statistically significant(P<0.05).The sensitivity,specificity and accuracy of CT plain scan and CTA in the diagnosis of AIO were higher than those of X-ray plain film.The sensitivity,specificity and accuracy of CTA in the diagnosis of AIO were higher than those of CT plain scan,and the difference was statistically significant(P<0.05).Conclusion CTA has a high detection rate and good diagnostic efficiency in the diagnosis of AIO,which is of high value in clinical popularization.
