【摘要】 目的:探讨脾动脉分支在部分脾栓塞术中的临床意义。方法:总结32例部分脾栓塞术临床病例资料,观察16例脾动脉铸型标本,探讨脾动脉分支在部分脾栓塞术中的临床意义。结果:①栓塞程度为45%~70%,有3例出现急性胰腺炎。②脾内不小于1mm内径动脉支数为22(18~31)支,来自上、下脾叶动脉的分支支数大致相等。脾上、下叶之间存在无血管区。胰尾动脉1~2支,大多数发自脾动脉下叶支,起始内径为(1.14±0.10)mm,与其他动脉的吻合支细、少。结论:超选择性插管可将脾栓塞程度控制在50%左右。超选择性插管和选用2mm×2mm×2mm明胶颗粒,可避免误栓胰尾动脉。更多还原

【Abstract】 Objective:To study the clinical significance of splenic arterial branches in partial splenic embolization.Methods:The significance of splenic arterial branches in partial splenic embolization were discussed by summarizing 32 cases treated by partial splenic embolization and observing splenic arterial branches in 16 samples.Results:①The splenic embolization proportions were 45～70%.Acute pancreatitis occurred in 3 cases after operation.②The average number of arteries approximately over 1mm in internal diameter was 22(18～31),which equally distributed in lobus arteries superior and inferior.There were avascular zones between lobus superior and inferior.1～2 caudal pancreatic arteries,which initial internal diameters,and its anastomotic ramus with other arteries were fewer and tenuity,most originated from inferior branches of splenic artery were(1.14±0.10)mm.Conclusion:Ultraselective intubating into splenic arterial branches could control the splenic embolism proportion at about 50%.Application of ultraselective intubation and 2mm×2mm×2mm gelfoam particles could avoid pluging the caudal pancreatic arteries.更多还原
