| 目的 探讨CT手动法、IQQA半自动法、门静脉右支流域法测量右半肝体积与术中移植肝体积的相关性,分析其影响因素。 方法 对79名供体分别以CT手动法及IQQA半自动法测量全肝体积(以CTV全、IQQAV全表示)及右半肝体积(以CTV、IQQAV表示),用门静脉右支流域法测量右半肝体积(以RPVTV表示),并分别将3种术前右半肝体积测量结果与术中右半肝体积(IOV)对比,计算术前所测3种右半肝质量与受体体质量的比例(GRWR),比较其准确性。 结果 IQQAV大于IOV,其与IOV的相关性比CTV与IOV的相关性更好。RPVTV与IOV亦有相关性,但相关性不如IQQAV。CTV及IQQAV的GRWR各有1例小于0.8%。 结论 与CTV相比,IQQAV更准确。 |

| Objective To investigate the correlation of the right lobe volume obtained by IQQA semiautomatic method, traditional CT manual method, right portal vein territory method and intraoperation volume in living donor liver transplantation using right lobe graft, and to explore the impact factors. Methods Total liver volume and right hemiliver volume of seventy-nine donors were measured respectively by traditional CT manual method (CTVall, CTV) and IQQA semiautomatic method (IQQAVall, IQQAV) by drainage of the right branch of portal (RPVTV). Then preoperative right hemiliver volume measured by three methods were compared with intraoperational volume (IOV), and graft recipient weight ratio (GRWR) were calculated. Results IQQAV was bigger than IOV, and had little correlation with IOV than CTV. RPVTV had better correlation with IOV than IQQAV. GRWR of CTV and IQQAV less than 0.8% was found in 1 case, respectively. Conclusion Compared with the CTV, IQQAV is more accurate in evaluation on liver volume in living donor liver transplantation. |
