Objective To assess the application value of 256-slice spiral CT angiography in displaying splenic artery and splenic lobar artery before surgical operation. Methods Data of 200 patients who received abdominal enhanced CT were retrospectively analyzed. The type and end type of splenic artery were observed. Diameter of the end of the splenic artery, splenic upper lobe artery and splenic lower lobe artery was measured. The capability of CTA in displaying splenic lobar artery was assessed. Results The splenic artery, splenic lobe artery and splenic artery in the whole 200 patients were vividly displayed. Diameter of the spleen upper and lower lobe artery, and the end of the splenic artery had statistical differences between female and male patients (all P<0. 05), while different age exhibited no statistical significance (all P>0. 05). Conclusion 256-slice spiral CT angiography can display anatomy and variation of splenic artery and splenic lobar artery clearly and directly, therefore providing powerful guarantee for presurgical evaluation of splenic surgery.%目的 评价术前256层螺旋CTA显示对脾叶动脉及脾段动脉的能力.方法 回顾性分析200例于我院接受腹部增强扫描的患者资料,观察脾动脉终末端分型、脾叶动脉分型,测量脾动脉末端直径、脾上下叶动脉直径,评价CTA对脾叶、脾段动脉的显示能力.结果 200例脾动脉、脾叶动脉及脾段动脉均显示清晰.脾上下叶动脉直径、脾动脉末端直径在不同性别间差异有统计学意义(P均＜0.05),在青中年和老年间差异均无统计学意义(P均＞0.05).结论 256层螺旋CTA能清晰、直观显示脾叶、脾段动脉的正常解剖及变异,可为外科手术前评估提供有力保障.
