| 摘 要： | 目的:探讨双源CT(DSCT)腹部血管成像在肠缺血性疾病诊断中的价值。方法:对8例临床拟诊为肠缺血性疾病的患者行DSCT腹部动静脉血管成像,利用工作站分别对腹部血管尤其是肠系膜动静脉血管进行重组,结合横断面图像对疾病进行诊断,评价缺血肠管出现的异常征象,并将DSCT与数字减影血管造影(DSA)结果进行比较。所有患者均经介入或手术治疗。结果:8例患者DSCT腹部动静脉血管成像:诊断肠系膜上动脉栓塞4例,动脉期DSCT横断面、MIP及VRT重组图像表现为肠系膜上动脉不同程度的充盈缺损;肠系膜上动脉斑块并形成致相应管腔明显狭窄(管腔的狭窄程度大于75%)的1例;肠系膜上静脉血栓形成3例,其中伴有门静脉血栓1例,DSCT显示肠系膜上静脉不规则的充盈缺损。DSCT表现为不同程度肠梗阻5例,表现为肠腔内见气液平,其中4例强化后肠壁呈层状增厚,腹腔内不同程度积液。与手术及DSA结果比较DSCT诊断准确率100%。结论:DSCT能准确诊断急性肠缺血并明确病因,是肠系膜血管缺血性疾病理想的检查方法之一。
