目的探讨肠系膜CT血管造影表现与肠系膜脂膜炎(mesenteric panniculitis,MP)的相关性。方法对20例MP患者(MP组)在左肾静脉入下腔静脉层面测量肠系膜上动脉直径(SMA直径)、肠系膜上静脉直径(SMV直径),观察肠系膜上动脉有无梳齿征、管壁钙化、细小血管分支栓塞、肠系膜静脉有无栓塞等,并与20例对照组进行比较,并对其进行分析。结果两组SMA、SMV直径比较,差异无统计学意义(P>0.05)。MP组与对照组患者中,SMA梳齿征分别为13、0例,动脉壁钙化分别为12、3例,壁管毛糙分别为15、1例。两组比较差异有统计学意义(P<0.05)。肠系膜静脉栓塞分别为3、1例对比差异无统计学意义(P>0.05)。结论肠系膜脂膜炎对SMA、SMV的主干管径无影响,血管表现主要为梳齿征、动脉壁钙化、毛糙、中小分支闭塞,肠系膜血管CTA检查对诊断MP有一定诊断意义。
Objective To investigate the relationship between mesenteric panniculitis (MP) and mesenteric CT angiography. Methods The diameters of superior mesenteric artery (SMA) and superior mesenteric vein (SMV) were measured in the left renal venous of 20 MP patients (MP group). The superior mesenteric artery Calcification, small vessel branch embolism, mesenteric vein with or without embolization, and compared with 20 cases of control group, and analyzed. Results There was no significant difference in the diameters of SMA and SMV between the two groups (P> 0.05). In the MP group and the control group, SMA comb tooth sign were 13,0 cases, arterial wall calcification were 12,3 cases, wall rough were 15,1 cases. The difference between the two groups was statistically significant (P <0.05). Mesenteric vein thrombosis were 3,1 cases, respectively, the difference was not statistically significant (P> 0.05). Conclusions Mesenteric meningitis has no effect on the main diameter of SMA and SMV. The main vascular manifestations are comb tooth sign, arterial wall calcification, rough and small branches occlusion, and mesenteric vascular CTA examination may be of diagnostic value in the diagnosis of MP.
