摘要
目的:探讨MSCT血管成像(MSCTA)在儿童肠旋转不良伴中肠扭转中的诊断价值。方法:回顾性分析经手术证实的11例肠旋转不良伴中肠扭转患儿的临床资料和CT表现,其中男8例,女3例,年龄13天~8岁,中位年龄2.3岁。11例患儿均行CT平扫及增强检查,并采用多平面重组(MPR)、最大密度投影(MIP)、容积再现(VR)技术对图像进行后处理。结果:10例患儿表现为"漩涡征",1例患儿表现为"换位征",6例患儿可见"鸟喙征",5例患儿表现为肠管扩张、积液,4例可见肠壁及肠系膜肿胀,4例可见腹盆腔积液。结论:MSCTA对诊断儿童肠旋转不良伴中肠扭转具有重要价值。
Objective：To assess the value of multi-slice spiral CT angiography （MSCTA） in the diagnosis of malrota tion with midgut volvulus in children. Methods：The clinical and MSCTA findings of eleven pediatric patients with rnalrota tion with rnidgut volvulus proved by surgery were retrospectively analyzed. There were 8 males and 3 females,with the age ranged {rorn 13d^8y,mean age 2.3y. All patients underwent CT scanning without and with contrast administration, post processing techniques including multi-planar reformation （MPR）, maximum intensity projetion （MIP） and volume rendering （VR） were performed. Resuts： Among these 11 cases,＂whirl sign＂ was demonstrated in 10 cases, inversion of SMA and SMV in one case,＂beak sign＂ in 6 cases, dilatation of intestinal lumen and fluid retention in 5 eases, edema of intestinal wall and mesentery in 4 eases, abdominal and pelvic ascites in 4 cases. Conclusion： MSCTA has important value in the diagnosis of malrotation with rnidgut volvulus in children.
