肝动脉栓塞治疗肝脏海绵状血管瘤的疗效分析

Analysis of therapeutic effects of hepatic artery embolization on cavernous hemangioma of liver

目的探讨肝动脉栓塞在治疗肝脏海绵状血管瘤中的应用价值。方法采用Seldinger技术,对57例肝脏海绵状血管瘤患者,用平阳霉素与超液态碘化油乳剂和明胶海绵栓塞肝动脉。病灶较大的,间隔2个月再次行栓塞治疗。术后0.5~1年行CT或MRI复查。结果 8例行2次栓塞,2例行3次栓塞,57例患者共栓塞69次。术后复查,病灶缩小〉50%、缩小25%~50%、缩小〈25%分别为28例、24例、5例,有效率91.2%。病灶缩小〈25%的5例,术前CT、MRI增强检查显示病灶强化不明显。结论肝脏海绵状血管瘤行肝动脉栓塞疗效明显,但对于术前MRI、CT扫描增强检查增强不明显者的疗效不满意。

Objective To explore the application value of hepatic artery embolization in the treatment of cavernous hemangioma of liver（CHL）.Methods The hepatic arteries of 57 cases of CHL were embolized with pingyangmycin,iodized oil emulsion and gelatin sponge using Seldinger technology.The larger lesions were embolized again with the interval of two months.CT or MRI fellow-up were done in 6 months-1 year after operation.Results 8 of 57 cases were embolized 2 times,2 of them 3 times,and 57 cases were embolized 69 times in total.The fellow-up examination in 6 months-1 year after operation showed that lesions shrinking above 50%,25%-50% and less than 25% occurred in 28,24 and 5 cases,respectively.The total efficient rate was 91.2%.Preoperative CT and MRI showed that lesions shrinking less than 25% were not enhanced obviously.Conclusion Hepatic artery embolization is of obvious effectiveness to treat CHL,but its therapeutic effects on inapparent enhanced lesions according to preoperative MRI and CT is not satisfied.
