摘要 目的:探讨多层螺旋CT(MSCT)在诊断肠缺血的应用价值。方法:收治缺血性肠病患者20例,采用多层螺旋CT进行扫描。结果:MSCT直接征象:①肠系膜上静脉血栓:主要表现为静脉血管腔内充盈缺损,静脉血管密度增高或呈等密度;②肠系膜上动脉痉挛:主要表现为血管重建显示动脉变细,分支减少;③肠系膜上动脉栓塞:主要表现为动脉腔内低密度充盈缺损,肠系膜上动脉密度增高;④肠系膜上动脉狭窄:主要表现为脉管腔狭窄,平扫多显示管壁钙化。本组20例患者肠系膜上静脉血栓11例,肠系膜上动脉痉挛4例,肠系膜上动脉栓塞1例,肠系膜上动脉狭窄4例。MSCT间接征象:主要表现为腹腔积液,肠壁积气,肠系膜水肿,增强肠壁不强化或强化减弱,肠管内气液平,肠管扩张,密度异常,肠壁厚度改变。结论:MSCT能准确诊断肠缺血并明确病因,有助于判断缺血程度。
