彩色多普勒超声在胎盘植入中的诊断价值

Clinical value of color Doppler ultrasound in diagnosis of placenta implantation

目的：探讨彩色多普勒超声（ CDFI）在胎盘植入（ PI）中的诊断价值。方法回顾性分析2010-01～2013-11经手术及病理证实的56例PI患者的超声声像图特征、血流分布和血流动力学变化情况。结果56例PI患者，CDFI成功检出38例，漏诊18例，检出率为67.9％。结论 CDFI检查有助于PI的检出，结合病史，重点分析血流分布特点有助于降低PI漏误诊率。

Objective To investigate the clinic value of color Doppler flow imaging （CDFI） in the diagnosis of placenta implantation （ PI） .Methods Fifty-six cases of PI confirmed by surgery and pathology were retrospectively analyzed by two-dimensional characteristics , blood flow distribution and hemodynamic changes .Results In 56 cases of PI, 38 cases were successfully detected by CDFI with a detection rate of 67.9%,but 18 cases were misdiagnosed . Conclusion CDFI can improve the detection of PI , paying carefully attention to the clinic history and the character-istic of flow distribution is helpful for reducing the misdiagnosis rate .
