摘　　要：目的探讨腹部内脏动脉瘤双源CT血管造影(CTA)的表现。方法回顾性分析30例腹部内脏动脉瘤患者CT原始及后处理图像,主要应用容积显示(VR)、最大密度投影(MIP)、曲面重组(CPR)、多平面重组(MPR)等后处理技术,进行图像重建观察动脉瘤情况,并结合横断面图像对疾病进行诊断。结果 30例腹部内脏动脉血管造影成功,图像清晰。CTA能清晰显示腹部内脏动脉瘤,包括3例结节性多动脉炎患者,均可见多发内脏动脉瘤,此外单发动脉瘤中包括:脾动脉瘤12例、肝动脉瘤3例、肾动脉瘤8例(1例患者双肾均可见一单发动脉瘤)、腹腔干动脉瘤1例、腹腔干假性动脉瘤1例、肠系膜上动脉瘤3例。结论双源CT及其后处理技术对腹部内脏动脉瘤及相关疾病有很好的诊断价值,为临床治疗提供了依据。Objective To investigate the performance of abdominal visceral artery aneurysm in dual‐source CT angiogra‐phy （CTA） and to evaluate the clinical value of CTA in the diagnosis of abdominal visceral artery aneurysm .Methods Thirty patients of spontaneous abdominal visceral artery aneurysm were analyzed retrospectively and combined the original and post‐processing images （VR ,CPR ,MIP ,MPR） for diagnosis .Results 30 cases of patients with abdominal visceral artery aneurysm were successfully completed the CT angiography ,and the images were clear .CTA can clearly display the aneurysm ,including 3 polyarteritis nodosa patients who had multiple viscera aneurysm .Besides ,28 patients of solitary an‐eurysm included 12 cases of dplenic aneurysm ,3 cases of hepatic artery aneurysm ,8 cases of renal artery aneurysm （one of patients had aneurysm in bilateral respectively） ,1 case of celiac trunkaneurysm ,1 case of pseudoaneurysm of celiac trunk and 3 cases of superior mesenteric aneurysm .Conclusion Dual‐soure CT angiography and post‐processing technology have a good diagnostic valve for abdominal visceral artery aneurysm and relative disease and it provides the basis for clinical di‐agnosis and treatment .
