| 中文摘要: |
| 目的：总结急性肠系膜缺血（AMI）的临床资料及CT 影像特征并探讨多层螺旋CT（multi-slice spiral computed tomography，
MSCT）对该病的诊断价值。方法：回顾性分析经临床或手术证实的54 例AMI 患者的CT 和临床资料，包括其发病时间、主要症
状、体征、相关实验室检查指标，评价并分析异常的MSCT 表现。结果：54 例均以非特异性腹痛为首发症状，其中肠系膜上静脉
血栓形成(SMVT)38 例，肠系膜上动脉栓塞(SMAE)12 例，肠系膜上动脉血栓形成(SMAT)4 例。MSCT诊断AMI 的直接征象为血
管内充盈缺损（43 例），间接征象包括：肠壁增厚35 例，“靶征”16 例，肠管扩张20 例，“缆绳征”22 例，肠壁积气征13 例，“薄壁样
征”12 例，腹腔积液34 例。结论：AMI的临床表现缺乏特异性，MSCT 检查可准确诊断AMI并明确缺血程度、范围，对指导治疗具
有较高的应用价值。 |

| Objective: To sumup the clinical data and CT features of the acute mesenteric ischemia (AMI) and explore the value
of multi-slice spiral computed tomography (MSCT) in diagnosis of AMI.Methods:CT features and clinical data of 54 cases with clinical
or surgically proven AMI were retrospectively analysed,including the onset time, main symptoms, signs and the indexes of laboratory
examination, and the abnormal MSCT findings were analyzed. Results: All 54 cases presented with initial symptom of non-specific
abdominal pain, including superior mesenteric venous thrombosis (SMVT,n=38), superior mesenteric artery embolization(SMAE,n=12),
superior mesenteric artery thrombosis (SMAT,n=4). The direct sign of AMI in MSCT images was filling defect in mesenteric vessels
(n=43). The indirect signs included thickening of bowel wall(n=35), target sign(n=16), bowel lumen dilatation(n=20), strand sign(n=22),
pneumatosis of bowel wall(n=13), thin bowel wall(n=12) and ascites(n=34).Conclusion:AMI lacks specific clinical manifestations, the
degree and extension of mesenteric ischemia can be accurately diagnosed by MSCT scan, which had an important clinical value for
guiding the treatment of AMI. |
