目的探讨肠系膜损伤的CT表现特征。资料与方法回顾18例经手术证实肠系膜损伤患者的CT检查结果,采用多窗技术分析其CT征象。结果18例患者的CT图像均显示有腹膜腔内游离积液/积血及肠系膜脂肪内渗出,其中14例可见肠系膜内血肿,13例可见肠壁增厚及增强后异常强化,7例合并肠管损伤可见肠腔外游离气体,2例可见血管内对比剂外溢。CT表现均与手术结果一致。结论肠系膜损伤可出现多种CT表现,采用多窗技术分析并正确认识其CT征象有助于避免漏诊和误诊。
Objective To investigate the CT features of mesenteric injury. Materials and Methods 18 cases of mesenteric injury confirmed by surgery were retrospectively reviewed. The CT findings were analyzed by multi-window technique. Results The CT images of 18 patients showed peritoneal effusion / hemorrhage and mesenteric fat exudation. Among them, 14 cases showed mesenteric hematoma, thickened intestinal wall and enhanced abnormal enhancement in 13 cases, 7 cases were merged Bowel injury visible intestinal free gas, 2 cases of intravascular contrast agent spillover. CT findings are consistent with the surgical results. Conclusion There are many CT findings of mesenteric injury. Using multi-window technique to analyze and correctly diagnose CT signs can help avoid misdiagnosis and missed diagnosis.
