摘　　要：目的探讨以急性腹痛为主要症状的血管源性疾病的MSCT表现。方法回顾分析57例血管源性急腹症患者的临床资料及MSCT表现,所有患者均行腹部64层螺旋CT平扫、动脉期及静脉期增强扫描,常规进行冠状位、矢状位MPR重建,38例患者进行了血管三维重建,重建方法为CPR、MIP、VR。结果 57例患者中,主动脉夹层10例,腹主动脉瘤破裂5例,髂总动脉瘤破裂3例,肠系膜上动脉栓塞14例,肠系膜上静脉栓塞5例,自发孤立性肠系膜上动脉夹层5例,肾动脉血栓栓塞10例,脾梗塞5例,MSCT诊断符合率100%。结论 MSCT增强及三维血管成像是血管源性急腹症有效的无创性检查方法。Objective To explore the diagnostic value of MSCT in patients with acute abdominal pain caused by vascular diseases.Methods The clinical data and MSCT manifestations of 57 patients with acute abdomen caused by vascular diseases were retrospectively analyzed.All the patients underwent abdominal CT scan,arterial phase and venous phase enhancement,and were conducted with coronal and sagittal multi-planar reformation（MPR） routinely.3D reconstruction of blood vessels was performed to 38 patients.The method of reconstruction was curved planar reconstruction（CPR）,maximal intensity projection（MIP）,volume rendering（VR）.Results Of the 57 cases：10 cases were aortic dissection;5 cases were rupture of abdominal aortic aneurysm;3 cases were rupture of common iliac artery aneurysm;14 cases were superior mesenteric artery embolism;5 cases were superior mesenteric vein embolism;5 cases were spontaneous isolated superior mesenteric artery dissection;10 cases were renal artery embolism;5 cases were splenic embolism.The diagnose accordance rate of MSCT was 100%.Conclusion Contrast enhanced MSCT scanning and three dimensional vessel reconstructions are effective and noninvasive methods for detecting acute abdomen caused by vascular diseases.
