经阴道超声检查联合静脉血与腹腔血HCG比值在异位妊娠中的诊断价值

Diagnostic value of transvaginal ultrasonography combined with HCG ratio of venous blood and abdominal blood in ectopic pregnancy

目的探讨经阴道超声检查联合静脉血与腹腔血绒毛膜促性腺激素(HCG)比值在异位妊娠中的诊断价值。方法选取2017年8月~2018年8月在我院接受妊娠检查的120例孕妇作为研究对象,根据诊断金标准确诊为异位妊娠的患者60例作为研究组,将检查结果显示正常妊娠的孕妇60例作为对照组,对两组患者均进行阴道超声检查及静脉血与腹腔血HCG水平检查。比较两种检查方法单独使用以及联合使用时的灵敏度、特异性以及准确率;分析阴道超声检查与静脉血与腹腔血HCG比值检查联合使用对异位妊娠的诊断价值。结果阴道超声结果显示,宫腔未见妊娠囊,子宫内膜厚度<1.05cm,双附件未见明显包块,可见较为明显的盆腔积液;研究组患者的腹腔血与静脉血HCG比值显著高于对照组,差异有统计学意义(P<0.05);联合检查的灵敏度、特异性以及准确率均显著高于阴道超声检查、静脉血与腹腔血HCG比值检查,差异有统计学意义(P<0.05)。结论阴道超声检查联合静脉血与腹腔HCG比值检查诊断异位妊娠的准确率与灵敏度较高,明显优于单独检查,具有临床应用价值,值得推广。

Objective To explore the diagnostic value of transvaginal ultrasound combined with human chorionic gonadotropin (HCG) ratio of venous blood and abdominal blood in ectopic pregnancy. Methods A total of 120 pregnant women who underwent pregnancy examination in our hospital from August 2017 to August 2018 were selected as the research subjects, 60 patients diagnosed with ectopic pregnancy according to the diagnostic gold standard were selected as the research group, and 60 pregnant women with normal pregnancy as the control group, vaginal ultrasonography and HCG levels in venous and abdominal blood were examined in both groups. The sensitivity, specificity and accuracy of the two methods were compared when they were used alone or in combination. The diagnostic value of vaginal ultrasound combined with HCG ratio of venous blood and abdominal blood in ectopic pregnancy was analyzed. Results The results of transvaginal ultrasound showed that no gestational sac was found in uterine cavity, the thickness of endometrium was less than 1.05 cm, no obvious mass was found in both appendages, and more obvious pelvic effusion could be seen. The HCG ratio of abdominal and venous blood in the study group was significantly higher than that in the control group, the difference was significant (P<0.05). The sensitivity, specificity and accuracy of combined examination were significantly higher than those of vaginal ultrasonography and HCG ratio of venous blood to abdominal blood, the differences were significant (P<0.05). Conclusion Vaginal ultrasonography combined with intravenous blood and abdominal HCG ratio has higher accuracy and sensitivity in the diagnosis of ectopic pregnancy, which is obviously superior to the single examination. It has clinical application value and is worth popularizing.
