MSCT在探讨肠系膜脂膜炎淋巴结与血管关系中的价值

Value of MSCT in Exploring the Relationship between Venae Mesenterica Superior and Lymph Nodes in Mesenteric Panniculitis

目的探讨MSCT双期(平扫及动、门脉期)增强扫描在肠系膜脂膜炎淋巴结与肠系膜血管关系中的作用。方法回顾分析我院2010年1月-2021年6月期间随访确诊并具有双期增强的肠系膜脂膜炎患者130例,并随机选取具有双期增强的120例非肠系膜脂膜炎患者作为对照组。测量二组肠系膜上动静脉及淋巴结在双期的CT值及绘出其增强的趋势图,计数并统计分析。结果脂膜炎组肠系膜上动脉、静脉及淋巴结在双期增强的CT值分别为:45.32±6.94、388.94±112.16、147.59±23.28,44.79±5.67、66.40±10.92、155.90±23.98,22.42±10.79、55.10±17.81、76.70±25.32;对照组肠系膜上动静脉在的CT值分别为:45.65±7.12、390.57±110.47、147.33±19.58,45.20±7.48、72.62±18.60、162.24±26.51。脂膜炎与非脂膜炎组肠系膜上静脉双期CT值差异明显(P<0.05),二组肠系膜上动脉CT值差别不明显(P>0.05)。脂膜炎组肠系淋巴结强化明显,与膜上静脉强趋势图相近,但二者CT值差异明显(P<0.05)。结论肠系膜脂膜炎淋巴结增强明显,并与强化异常的肠系膜上静脉强化趋势类似,提示淋巴结可能由肠系膜上静脉演变而来。

Objective To investigate the value of MSCT double phase scan(plain and dynamic and portal phase)in CT diagnosis the relationship between lymph nodes and mesenteric vessels in mesenteric panniculitis.Methods 130 patients with mesenteric panniculitis with double phase enhancement were reviewed in our hospital between January 2010 and June 2021,and 120 patients with non-mesenteric panniculitis with double phase enhancement were randomly selected as control group.The CT values of mesenterica superior arteries,veins and lymph nodes of the two groups were measured in double phase,and drawed their enhanced trend charts.counted and statistically analyzed.Results The enhanced CT values of mesenterica superior arteries,veins and lymph nodes in mesenteric panniculitis group were 45.32±6.94,388.94±112.16,147.59±23.28,44.79±5.67,66.40±10.92,155.90±23.98,22.42±10.79,55.10±17.81,76.70±25.32 respectively;The CT values of mesenterica superior arteries,veins in the control group were 45.65±7.12,390.57±110.47,147.33±19.58,45.20±7.48,72.62±18.60,162.24±26.51.There were significantly different according to the venae mesenterica superior CT values beween mesenteric panniculitis group and the control group(P<0.05)and no difference as to the CT values of their arteriae mesenterica superiores(P>0.05);thelymph node enhancement was evident in mesenteric panniculitis group,and enhanced trend map were similar to the venae mesenterica superior,but there weresignificantly different according to the CT values beween venae mesenterica superior and lymph nodes(P<0.05).Conclusion The mesenteric panniculitis lymph nodes was significantly enhanced and a similar trend chart to the venae mesenterica superior with enhancement decreased,which suggested that that the lymph nodes might evolve from the superior mesenteric vein.
