经导管肝动脉栓塞治疗肝海绵状血管瘤

Treating cavernous hemangioma of th e liver by means of transcatheter hep atic arterial embolization

目的:探讨肝海绵状血管瘤的最佳栓塞治疗方案,分析比较不同栓塞方法的疗效。材料与方法:41例肝海绵状血管瘤,按不同的栓塞方法分为3组:第1组:11例,为单纯超液态碘化油栓塞,简称LP组;第2组:18例,用1∶1碘化油与鱼肝油酸钠混合栓塞,简称LP+V组;第3组:12例,行1∶1碘化油与鱼肝油酸钠再加明胶海绵颗粒或条综合栓塞,简称LP+V+G组。采用SAS软件对栓塞治疗前后瘤体大小及染色面积的改变进行统计学分析。结果:3种不同的栓治方法分别使瘤体最大径cm由597±147,842±290,736±284缩小至450±177,588±250,442±214。两两之间比较结果表明,综合栓塞优于单纯栓塞。DSA所测量瘤体染色面积的改变与上述结果亦基本吻合。结论:①经导管肝动脉栓塞治疗肝海绵状血管瘤,方法简单、安全有效;

Objective:To investigate the best embolic schema and the efficiency of three different embolic methods.Materials and methods:Among the 41cases,there were 11case s were embolized using only Lipiodol(LP group),18cases were treated using Lipiodol and Varicocid with a proportion of 1∶1(LP +V group),and 12cases were embolized using Li piodol and Varicocid and Gelfoam(LP +V +G group).Tumor sizes and stain areas of before and after treatment were measured b y CT and DSA.Statistical analysis had been done using SAS.Results:Three different methods made tumor d iameter(cm)decreased from 5.97±1.47,8.42±2.90,7.36±2.84to 4.50±1.77,5.88±2.50,4.42±2.14respectively.Two of the t hree groups were compared ,It was ind icated that comprehensive embolization was better than the oth er two methods.The changing of tumor' s stain area was measured by DSA had also proved the same results.Conclusion:①Transcatheter hepatic arterial emb olization is easy and efficient.It c an be considered as the first therapeu-tic option in these cases;②The keys to success are the super sele ction of feeding arteries and the com prehensive embolization.
