摘　　要：目的 探讨64排螺旋CT血管造影及后处理技术在诊断孤立性肠系膜上动脉夹层(SIDSMA)中的意义和临床价值。方法 回顾性分析我院2021-2023年收治的23例SIDSMA患者的临床资料及多层螺旋CT血管造影图像,探讨SIDSMA的CT表现及对临床诊断的意义。结果 23例患者均可见明显的双腔样改变,20例显示内膜片,20例显示内膜破口;夹层范围18~62 mm,平均(40±7)mm;破口距肠系膜上动脉(SMA)起始部21~30 mm,平均(25±5)mm。结论 MSCT血管造影及图像后处理技术可以清晰、直观地显示SIDSMA的真假腔、内膜片、破口位置及与周围组织结构的关系,并可测量夹层范围、破口距SMA起始部距离等数据,对该病的诊断、治疗具有重要意义。Objective To explore the significance and clinical value of 64-slice spiral CT angiography and postprocessing technology in the diagnosis of isolated superior mesenteric artery dissection(SIDSMA).Methods The clinical data,multi-slice spiral CT angiography,and image post-processing technology of 23 patients with SIDSMA in our hospital from 2021 to 2023 were analyzed retrospectively,and the CT manifestations of SIDSMA were discussed.Results There were obvious double-lumen changes in all 23 patients,20 cases showed intimal film and 20 cases showed intimal rupture.The interlayer range is 18~62 mm,with an average of(40±7)mm.The break is 21~30 mm from the beginning of superior mesenteric artery(SMA),with an average of(25±5)mm.Conclusion MSCT angiog-raphy and image post-processing technology can clearly and intuitively display the true and false cavities,intima films,the position of rupture and its relationship with surrounding tissues and structures of SIDSMA,and can also measure the data such as the range of interlayer and the distance from the rupture to the beginning of SMA,which is of great significance to the selection of clinical treatment methods.
