【摘要】 目的 评价经腹彩色多普勒超声(TA-CDUS)联合经阴道彩色多普勒超声(TV-CDUS)对子宫瘢痕妊娠(CSP)的诊断价值。方法 选取68例子宫瘢痕妊娠患者作为研究对象, 所有患者分别进行TA-CDUS检查、TV-CDUS检查及TA-CDUS联合TV-CDUS检查, 并以病理结果为金标准, 比较不同检查方法的临床检出率及灵敏度、特异度、阳性预测值、阴性预测值、诊断符合率。结果 TA-CDUS检查的临床检出率为48.53%, TV-CDUS检查的临床检出率为67.65%, TA-CDUS联合TV-CDUS检查的临床检出率为83.82%;TV-CDUS检查的临床检出率高于TA-CDUS检查, TA-CDUS联合TV-CDUS检查的临床检出率高于TA-CDUS及TV-CDUS检查, 差异均有统计学意义(P<0.05)。TA-CDUS聯合TV-CDUS检查的灵敏度为95.00%、特异度为89.29%、阳性预测值为92.68%、阴性预测值为92.59%、诊断符合率为92.65%, 均高于TA-CDUS检查的50.00%、32.14%、51.28%、31.03%、42.65%和TV-CDUS检查的77.50%、60.71%、73.81%、65.38%、70.59%, TV-CDUS检查的灵敏度、特异度、阳性预测值、阴性预测值及诊断符合率均高于TA-CDUS检查, 差异有统计学意义(P<0.05)。结论 TV-CDUS与TA-CDUS联合检查可提高子宫瘢痕妊娠的诊断准确率及临床检出率, 是适于临床推广应用的影像学检查方法。

【Abstract】 Objective   To evaluate the value of transabdominal color doppler ultrasonography (TA-CDUS) and transvaginal color doppler ultrasonography (TV-CDUS) in the diagnosis of caesarean scar pregnancy (CSP). Methods   There were 68 cases of caesarean scar pregnancy as study subjects all detected by TA-CDUS, TV-CDUS and TA-CDUS combined with TV-CDUS. Taking the pathological result as the gold standard, the clinical detection rate, sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic coincidence rate by different examination methods were compared. Results   The clinical detection rate by TA-CDUS was 48.53%, which was 67.65% by TV-CDUS and 83.82% by TA-CDUS combined with TV-CDUS. The clinical detection rate by TV-CDUS was higher than that by TA-CDUS, and the clinical detection rate by TA-CDUS combined with TV-CDUS was higher than that by TA-CDUS and TV-CDUS, and the difference was statistically significant (P<0.05). The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic coincidence rate by TA-CDUS combined with TV-CDUS were 95.00%, 89.29%, 92.68%, 92.59% and 92.65%, which were higher than those by TA-CDUS 50.00%, 32.14%, 51.28%, 31.03%, 42.65% and TV-CDUS 77.50%, 60.71%, 73.81%, 65.38%, 70.59%. The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic coincidence rate by TV-CDUS was significantly higher than that by TA-CDUS, and the difference was statistically significant (P<0.05). Conclusion   Combined detection of TV-CDUS and TA-CDUS can improve the diagnostic accuracy and clinical detection rate, and is an imaging method suitable for clinical popularization and application.

随着二胎政策的普及以及我国高剖宫产率的特殊国情, 剖宫产手术后子宫瘢痕妊娠(cesarean scar pregnancy, CSP)在临床较常见, 由于受精卵异位妊娠于剖宫产后的术后瘢痕处, 在妊娠后期可能会出现危及孕妇生命的大出血甚至出现子宫破裂。采用有效的检查方法对子宫瘢痕妊娠进行诊断是临床需要解决的重要问题。TA-CDUS及TV-CDUS是目前诊断子宫瘢痕妊娠的首选方法, 但临床上TA-CDUS和TV-CDUS对子宫瘢痕妊娠诊断准确性的研究仍较少, 本院对两种检查方法诊断子宫瘢痕妊娠的临床价值进行对比, 结果报告如下。

1 资料与方法

1. 1 一般资料 选取2016年12月~2019年1月于本院超聲科确诊为子宫瘢痕妊娠的68例患者作为研究对象, 年龄24~39岁, 平均年龄(23.66±8.38)岁。所有患者均通过临床症状和病理检查确诊为子宫瘢痕妊娠, 均仅有过1次剖宫产手术, 停经38~84 d, 平均停经(62.38±12.88)d;人绒毛膜促性腺激素(HCG)尿检为阳性。……
