肝移植后彩色多普勒超声的应用

背景：肝移植后监测移植肝脏并发症的发生情况,对肝移植的成功率及延长患者生存时间具有十分重要的意义。目的：评价彩色多普勒超声对肝移植后并发症的监测效果。方法：由作者采用电子检索的方式,在万方数据库（http：//www.wanfangdata.com.cn/）及Medline数据库（http：//www.ncbi.nlm.nih.gov/pubmed/）中以＂彩色多普勒超声,肝移植,移植后并发症＂为关键词,检索1990-01/2010-12有关彩色多普勒超声对肝移植后并发症监测效果的文章,共查到相关文献60余篇。经阅读标题、摘要、全文,排除内容重复、普通综述、Meta分析类文章后,筛选纳入22篇文献进行评价。结果与结论：彩色多普勒超声检查具有无创、简便、直观、定位准确及可动态观察等优点,在肝移植后不仅能有效地检测肝脏大小、移植肝形态,而且可以从内部回声及血流动力学方面为肝移植后并发症的早期诊断提供线索,对临床及早治疗、保证肝移植成功具有重要的作用,是肝移植后监测的首选影像学检查方法。

Application of color Doppler ultrasonography after liver transplantation

BACKGROUND：Monitoring complications of transplanted liver is of significance for increasing the success rate of liver transplantation and prolonging patients’ survival time. OBJECTIVE：To evaluate the effects of color Doppler ultrasonography on monitoring the complications of transplanted liver. METHODS：A computer-based retrieval was performed to search papers addressing the effects of color Doppler ultrasonography on monitoring the complications of transplanted liver published between January 1990 and December 2010 in Wanfang database （http：//www.wanfangdata.com.cn/） and Medline database （http：//www.ncbi.nlm.nih.gov/pubmed/） using key words ＂color Doppler ultrasonography, liver transplantation, complications post-transplantation. Finally, more than 60 papers were retrieved. By reading title, abstract, and full-text, review and Meta analysis papers and those with repetitive contents were excluded, and 22 papers were included in the final analysis. RESULTS AND CONCLUSION：Color Doppler ultrasonography is noninvasive, easy to operate, and can precisely locate the foci and dynamically observe the foci. It can effectively determine the size and morphology of transplanted liver and provide valuable information of internal echo and hemodynamics for monitoring the complications of the transplanted liver during the early stage after transplantation, which is very important for clinical early treatment and successful liver transplantation. Therefore, color Doppler ultrasonography is a preferred imaging examination for monitoring the complications after liver transplantation.
