目的探讨肠系膜上动脉栓塞(SMAE)的CT表现。资料与方法回顾性分析7例急性SMAE患者资料,男4例,女3例,平均年龄62岁,7例均行腹部CT平扫加增强扫描,用最大密度投影(MIP)、容积再现技术(VRT)图像后处理重组。结果肠系膜上动脉内充盈缺损7例,肠壁增厚5例,肠系膜上动脉增粗5例,肠腔扩张、肠壁菲薄和增厚3例,肠系膜上静脉及门静脉弥漫栓塞并肝缺血1例;腹腔积液2例。结论MSCT是诊断SMAE的一种可靠且无创的影像检查方法,对不明原因腹痛或临床怀疑SMAE的患者,应尽快行螺旋CT检查。
Objective To investigate the CT findings of superior mesenteric artery embolism (SMAE). Materials and Methods Retrospective analysis of 7 cases of SMAE patients, 4 males and 3 females, mean age 62 years old, 7 cases underwent abdominal CT scan and enhanced scanning with maximum density projection (MIP), volume rendering technology ( VRT) Image post-processing recombination. Results 7 cases of superior mesenteric artery filling defects, 5 cases of intestinal wall thickening, 5 cases of superior mesenteric artery thickening, intestinal dilatation, thin and thickening of the intestinal wall in 3 cases, superior mesenteric vein and portal vein embolism and liver ischemia 1 Case; 2 cases of ascites. Conclusion MSCT is a reliable and noninvasive imaging method for the diagnosis of SMAE. Spiral CT examination should be performed as soon as possible in patients with unexplained abdominal pain or suspected SMAE.
