摘要
目的 探寻影响脾栓塞程度的相关因素及其关系。方法 回顾性分析 90例部分性脾栓塞术 (partialsplenicembolization ,PSE)患者栓塞前、后的脾动脉造影表现 ,应用相关分析法总结大小为 1mm× 1mm× 1mm的明胶海绵颗粒数 (G值 )、内径约 1mm脾内动脉分支数 (A值 )、G/A比值、脾脏大小与脾栓塞程度 (Ee)的关系。结果 G/A比值与E(Ee× 10 0 )呈高度的正相关 (r =0 91) ,直线回归方程为 :E =11 5 + 5 0 5G/A ,即G =(E - 11 5 )A/5 0 5。结论 脾栓塞前根据预期栓塞程度和脾内动脉分支数确定明胶海绵用量 ,从而控制脾栓塞程度是可行的。
Objective\ To ascertain the relative factors of controlling the extents of splenic embolization and the relationships between them. Methods Splenic arteriographic films of pre-embolization and post-embolization were retrospectively analyzed in 110 patients,and the relationships between the extents of splenic embolization(Ee)and the quantity of gelfoam particles used(G),splenic artery branches about 1 mm diameter(A),G/A,the extents of splenic enlargement were studied by linear regression and correlation. Results There was a high positive correlation( r =0.91)between E(Ee×100)and the G/A ratios.The linear regression equation is G=(E-11.5)A/50.5. Conclusion It's entirely possible to control the extents of splenic embolizatin by injecting these gelfoam particles which were determined by aforementioned equation. [
