【摘要】 目的:探讨高频彩超在宫外孕早期诊断中的价值。方法:临床诊断的宫外孕患者50例,经超声、血清孕酮检查,手术及病理证实。结果:超声发现附件包块48例,诊断宫外孕45例,超声诊断的敏感性为89.5%、特异性92.5%、阳性预测值43.2%、阴性预测值98.8%。50例宫外孕患者中,孕酮<10 ng/ml者24例,敏感性、特异性、阳性预测值和阴性预测值分别为52.5%、67.5%、26.2%、91.2%。高频彩超对早期宫外孕诊断的敏感性较血清孕酮高(P<0.01)。结论:高频彩超可以早期确诊宫外孕,指导临床治疗,改善其预后。

The Value of High frequency Color Doppler Ultrasound in Early Diagnosis of Ectopic Pregnancy/WANG Jing-cai,SHEN Qiang.//Medical Innovation of China,2012,9(13):095-096
【Abstract】 Objective:To explore the value of high frequency and color doppler ultrasound in early diagnosis of ectopic pregnancy.Methods:50 cases of ectopic pregnancy were diagnosised by ultrasound,serum progesterone and confirmed by surgery and pathology.Results:The ultrasound found 48 cases of adnexal masses,45 cases diagnosed with ectopic pregnancy,The ultrasonic diagnostic sensitivity,specificity,positive predictive value and negative predictive values were 89.5%,92.5%,43.2%,98.8%.Among 50 cases of ectopic pregnancy patients,progesterone<10 ng/ml in 24 cases,the sensitivity,specificity,positive predictive value and negative predictive values were 52.5%,67.5%,26.2%,91.2%.The sensitivity of high frequency color doppler for the diagnosis of early ectopic pregnancy was higher than the serum progesterone(P<0.01).Conclusion:High frequency color doppler ultrasound in the early diagnosis of ectopic pregnancy can guide clinical treatment and improve the prognosis.

宫外孕是妇科常见急症,一旦发生破裂或流产导致腹腔内出血,可危及生命,其发生率近十年呈上升趋势[1]。早期诊断宫外孕对挽救妇女生命、保障生育能力非常重要。因此,如何利用各种检查方法进行宫外孕的早期诊断,仍然是当今妇产科极为关注的课题。
1 资料与方法
1.1 一般资料 2008年1月-2012年2月笔者所在医院临床诊断的宫外孕患者50例,术前均进行超声、血清孕酮检查,手术、病理及随访证实。年龄18~43岁,平均28岁。停经时间为5~8周,实验室检查尿绒毛膜促性腺激素(hCG)阳性40例,弱阳性10例,下腹痛32例,阴道不规则出血18例。
1.2 仪器及方法 应用GE-Vivid 7型彩色多普勒超声诊断仪,经腹探头频率3.5 MHz,经阴道探头频率6.0~10.0 MHz。经阴道超声检查,观察子宫大小、宫内有无孕囊存在,观察附件区包块的大小、回声特征,盆腹腔有无游离液体,然后用彩色多普勒观察子宫内膜血流情况,当发现可疑妊娠囊后,观察妊娠囊周边有无半环状血流信号,如有血流信号显示,将取样容积放置血流信号处,使声束与血流方向的夹角小于60°,取多普勒血流频谱 ......
