彩色多普勒超声联合二维超声诊断瘢痕子宫并前置胎盘植入的价值分析

Value of color Doppler ultrasonography combined with two-dimensional ultrasonography in the diagnosis of scar uterus complicated by placenta previa implantation

目的 探讨彩色多普勒超声联合二维超声对瘢痕子宫并前置胎盘植入的诊断价值.方法 选取疑似瘢痕子宫合并前置胎盘植入患者74例为研究对象,分别采用二维超声、二维超声联合彩色多普勒超声诊断对患者进行追踪,以手术病理结果作为金标准.结果 74例患者中,手术病理确诊为瘢痕子宫合并前置胎盘植入37例.二维超声诊断敏感性、特异性、准确性、阳性预测值、阴性预测值（67.57％、83.78％、75.68％、65.79％、86.11％）均低于二维超声联合彩色多普勒超声（94.59％、97.30％、95.59％、97.22％、94.74％）,差异有统计学意义（P＜0.05）.结论 彩色多普勒超声联合二维超声诊断瘢痕子宫合并前置胎盘植入准确率高,可作为术前预测病情的首选方案.

Objective To investigate the values of color Doppler ultrasonography combined with two-dimensional ultrasonography in the diagnosis of scar uterus complicated by placenta previa implantation.Methods Seventy-four patients who were suspected with scar uterus complicated by placenta previa implantation were selected as objects,and the two-dimensional ultrasonography and two-dimensional ultrasound combined with color Doppler ultrasonography were both applied for tracing patients.The surgical pathology was considered as the gold standard.Results In 74 patients,37 cases of scar uterus and placenta previa were confirmed by pathological result of operation.The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of two-dimensional ultrasound diagnosis （67.57%,83.78%,75.68%,65.79%,86.11%） were lower than those of the two dimensional ultrasound combined with color Doppler ultrasonography （94.59%,97.30%,95.59%,97.22%,94.74%）,correspondly,and the differences were statistically significant （all P 〈 0.05）.Conclusions The accuracy of color Doppler ultrasonography combined with two-dimensional ultrasonography in the diagnosis of scar uterus complicated by placenta previa implantation is higher,and it can be used as the first choice for predicting the condition before operation.
