摘　　要：目的目的探讨腹部多层螺旋CT平扫在高原地区急性肠系膜上静脉血栓(ASMVT)诊断的价值。方法方法回顾性分析确诊为ASMVT的腹部CT平扫图像(27例),并以健康(40例)及慢性高原病(CMS)患者(29例)的腹部CT平扫图像为对照组,比较各组的肠系膜上静脉直径及CT值的差异。结果结果ASMVT组肠系膜上静脉直径为(1.63±0.34)cm,CMS组(1.48±0.20)cm和健康对照组(1.21±0.14)cm,各组比较差异有统计学意义(P<0.05);ASMVT组肠系膜上静脉CT值为(63.24±6.13)HU,,CMS组(58.44±4.67)HU和健康对照组(45.83±4.16)HU,各组CT值比较差异有统计学意义(P<0.05);肠系膜上静脉CT值的最佳阈值55.47HU时,对诊断ASMVT的敏感度为88.89%,特异度为75.00%。结论结论CT平扫上如表现为肠系膜上静脉密度增高及周围脂肪间隙渗出高度提示ASMVT。Objective To investigate the value of abdominal multislice spiral CT plain scan in the diagnosis of acute superior mesenteric vein thrombosis(ASMVT)in plateau area.Methods 27 patients with ASMVT were retrospectively analyzed,and 40 healthy patients and 29 patients with chronic mountain disease(CMS)were taken as control group.The difference in diameter and CT value of superior mesenteric vein among all groups was compared.Results The diameter of superior mesenteric vein in ASMVT group was(1.63±0.34)cm,which was significantly larger than that in CMS group(1.48±0.20)cm and healthy control group(1.21±0.14)cm,and there was statistical difference among all groups(P<0.05).The CT value of superior mesenteric vein in ASMVT group was(63.24±6.13)HU,which was significantly higher than that in CMS group(58.44±4.67)HU and healthy control group(45.83±4.16)HU,and there was significant difference among all groups(P<0.05).When the optimal threshold of superior mesenteric vein CT value was 55.47HU,the sensitivity of the diagnosis of ASMVT was 88.89%and the specificity was 75%.Conclusion CT plain scan showed increased density of superior mesenteric veins and high peripheral adipose space leakage indicating ASMVT.
