摘要 目的对30例急性肠缺血和患者CT检查,来评价CT对急性肠缺血的诊断价值。方法30例急性肠缺血的患者均行CT平扫和增强扫描,均显示不同程度的有肠系膜及其血管(MRV)改变,并经手术病理及临床证实,其中肠系膜上动脉(SMA)栓塞10例,肠系膜上静脉(SMV)栓塞11例,肠系膜下静脉(IMV)栓塞2例,肠系膜动静脉栓塞4例(其中肠系膜扭转3例,小肠扭转1例)。非闭塞性肠灌注血量减少(NOI)3例(阑尾回盲部脓肿)。通过CT检查,详细分析其影像学表现特征。结果通过直接征象血管内充盈缺损27例,间接征象:局部肠腔狭窄伴近端扩张积液23例,肠壁增厚20例,肠壁密度改变26例,肠壁气肿15例,血管内积气2例,肠系膜水肿26例及腹水15例,腹腔及肠系膜处散在游离气体5例。结论对急性肠缺血病人行CT检查能较好显示MRV改变,结合其他的CT征象和临床实验室检查,均可对急性肠缺血做出较正确的诊断,同时也能观察到传统X线不能显示的并发症,较少漏诊及误诊率。
