摘　　要：目的 探讨高原地区肠系膜上静脉血栓(MVT)的MSCT表现及临床特征。方法 回顾性分析我院经临床及影像明确诊断为MVT患者的临床及MSCT影像资料。急慢性肠系膜血栓患者的临床及MSCT影像特征进行比较。结果 86例MVT患者中,31(36.05%)例有肝硬化病史,10(11.63%)例有慢性高原病病史。血栓累及肠系膜主干者23(26.74%)例,血栓累及主干及分支者32(37.21%)例,主干、分支及脾静脉血栓者31(36.05%)例。急性组MSCT平扫表现为受累血管增粗,密度增高,CT值为(55.05±9.33)HU,慢性组MSCT平扫表现为受累血管等或稍低密度影,CT值为(33.51±6.68)HU,部分可见血管变细和血管壁钙化,增强后均表现为充盈缺损,两组平扫CT值比较差异有统计学意义(t=11.464,P=0.000)。急性组及慢性组中血管外表现无显著差异(P>0.05)。结论 CT能清晰显示MVT患者血栓范围及血管外病变,可用于MVT的诊断及病变范围及程度的评估中。Objective To investigate the MSCT manifestations and clinical features of mesenteric vein thrombosis(MVT)in plateau area.Methods The clinical and MSCT imaging data of diagnosed with MVT in our hospital were retrospectively analyzed.The clinical and MSCT imaging features of patients with acute and chronic mesenteric thrombosis were compared.Results Among the 86 MVT patients,31(36.05%)patients had a history of cirrhosis,10(11.63%)patients had a history of chronic mountain sickness.There were 23(26.74%)cases of thrombosis involving the main trunk,53(61.63%)cases of thrombosis involving the trunk and branches of intrahepatic vein,and 32(37.21%)cases of thrombosis involving the trunk and branches of superior mesenteric vein.There were 31 cases(36.05%)with trunk,branch and splenic vein thrombosis.In the acute MVT group,plain MSCT scan showed thickening of the involved vessels and increased lumen density,and the lumen CT value was(55.05±9.33)HU.In the chronic MVT group,plain MSCT scan showed equal or slightly low density shadow of the involved vessels,and the CT value was(33.51±6.68)HU.Some of the vessels were thinner and the vascular wall calcified,and the enhancement showed filling defects.Plain CT values between the two groups were significantly different(t=11.464,P=0.000).There were no significant differences between acute group and chronic group in extravascular mesenteric manifestations(P>0.05).Conclusion MSCT can clearly show the range of thrombus and extravascular lesions in MVT patients,which can be used in the diagnosis of MVT and the range and extent of lesions.
