摘　　要：目的评价多层螺旋CT血管成像(MSCTA)在脾动脉瘤诊断中的价值。方法分析12例脾动脉瘤患者的MSCTA影像资料,结合原始图像和重组图像做出诊断;图像后处理方法包括多平面重组(MPR)、曲面重组(CPR)、最大密度投影(MIP)和容积再现(VR)等。结果 12例脾动脉瘤瘤体直径平均27 mm,MSCTA清晰的显示了脾动脉瘤的部位、大小、形态,在立体的显示脾动脉瘤及与邻近血管的关系优于传统血管造影。本组行包括胰尾、脾的脾动脉瘤切除术2例,脾动脉瘤切除加脾动脉重建术2例,介入治疗4例。结论多层螺旋CT血管成像是一种有效的无创性检查手段,有利于合理的治疗方案的制定,可作为脾动脉瘤诊断的首选检查方法。Objective To assess the clinical value of muhislice computed tomography angiography （ MSCTA ） in the diagnosis and treatment planning of splenic artery aneurysm. Methods Twelve patients with splenic artery aneurysms underwent MSCTA. The axial and 3D reconstruction images including multiplanar reformation （ MPR ）, curved planar reformation （ CPR ）, maximum intensity projection （MIP） and volmne rendering （VR） were reviewed. Results The mean diameter of the 12 anemysms was 27 ram. MSCTA demonstrated the location, size and morphology of the aneurysms clearly. MSCTA was superior to digital subtraction angiography with 3D display of the aneurysm and its relationship with surrounding structures. The patients were treated by resection of splenic aneurysm, spleen and pancreatic tail （2）, resection of splenic aneurysm and reconstruction of splenic artery （2）, and endovascular embolization （4）. Conclusions MSCTA is noninvasive and provides accurate 3D anatomic information for diagnosis and treatment planning of splenic artery aneurysms.
