肠系膜上静脉血栓形成的CT诊断价值

目的：探讨肠系膜上静脉血栓形成( SMVT)的CT诊断价值。方法回顾分析15例SMVT患者的影像学资料，并加以总结。结果15例SMVT患者中，肠管扩张积气、积液12例；肠壁水肿增厚伴密度改变8例；肠系膜血管增粗，脂肪渗出6例；肠系膜血管走行异常5例；肠系膜静脉管腔内充盈缺损15例，管壁强化13例。结论 CT能够清晰显示SMVT的直接征象与间接征象，并有助于外科术前指导和内科疗效评价。

Value of CT diagnosis for superior mesenteric vein thrombosis

Objective To evaluate the value of CT diagnosis for superior mesenteric vein thrombosis. Methods Imaging findings with superior mesenteric vein thrombosis in 15 cases were retrospectively analyzed. Results Among 15 cases with superior mesenteric vein thrombosis, 12 cases had bowel dilatation and/or air-fluid levels, 8 cases showed thickened bowel wall, 6 cases had mesenteric vascular en-largement and effusion of mesenteric, 5 cases displayed mesenteric vascular abnormal route, mesenteric vein lumen had filling defect in 15 cases, and venous wall was strengthened in 13 cases. Conclusion CT can demonstrate direct and indirect signs of superior mesenteric vein thrombosis clearly, which is effective for the surgery preoperative guidance and evaluation of medical treatment.
