摘要:
目的探究超声测量双侧子宫动脉搏动指数(uterine artery pulsatility index, PI)的差异在早期输卵管妊娠（tubal pregnancy，TP）诊断中的临床价值。方法回顾性分析2016年5月至2017年5月梅州市人民医院超声诊断中心诊断为TP的58例患者资料（观察组），另取同期早期宫内妊娠的58例孕妇资料作为对照组。观察组根据TP与黄体位置和β-人绒毛膜促性腺激素（β-human chorionic gonadotropin,β-hCG）水平分为A、B、C 3个亚组。A组（9例）为TP与黄体异侧；B组（22例）为TP与黄体同侧，β-hCG≤800 mIU/mL；C组（27例）为TP与黄体同侧，β-hCG>800 mIU/mL。观察双侧子宫动脉PI在各组中的差异情况，绘制子宫动脉PI差值（ΔPI）的ROC曲线并分析其诊断TP的灵敏度和特异度。结果①　TP与黄体同侧患者彩色多普勒超声显示功能侧舒张期丰富的血流信号，血流阻力较对侧降低；TP与黄体异侧，彩色多普勒超声探及双侧子宫动脉中等阻力血流。②　C组患者功能侧子宫动脉PI（219±078）低于非功能侧（287±062），差异有统计学意义（t=456，P<005）；A、B组和对照组患者双侧子宫动脉的PI差异无统计学意义（t=138，221，094，P>005）；C组患者ΔPI（1934±2253）大于对照组（312±1574），差异有统计学意义（t=542，P<005）；A组和B组患者ΔPI与对照组比较差异无统计学意义（t=142、174，P>005）。③　以灵敏度为纵坐标，1-特异度为横坐标，制作ΔPI的ROC曲线，曲线下面积为0715，当子宫动脉ΔPI>1888 %时，诊断TP的灵敏度和特异度最高，分别为5625 %和8223 %。结论早期TP胚胎活力及妊娠黄体联合作用可能对双侧子宫动脉PI产生影响，通过测量双侧ΔPI对早期TP诊断有一定的临床价值。
Abstract:
ObjectiveTo investigate the clinical value of ultrasonic measurement of bilateral uterine arterial pulsatility index(PI) in the diagnosis of early tubal pregnancy(TP). Methods58 patients diagnosed as TP in Meizhou City People's Hospital from May 2016 to May 2017 were divided into three groups, group A, B and C, according to the position of TP and corpus luteum and the level of β-hCG. Group A(9 cases) was TP and corpus luteum from side to side;Group B(22 cases) was TP and ipsilateral to the corpus luteum.β-hCG≤800 mIU/mL; Group C(27 cases) was TP and ipsilateral to the corpus luteum, β-hCG>800 mIU/mL. Another 58 cases of early intrauterine pregnancy were set as control group. To observe the difference of the bilateral uterine arterial PI in each group, to draw the ROC curve of the uterine artery Delta PI, and to analyze the sensitivity and specificity of the diagnosis of TP. Results① Color Doppler ultrasonography of TP and ipsilateral patients showed functional diastolic blood flow signal, blood flow resistance decreased compared with contralateral side; TP and corpus luteum, color Doppler ultrasonography and bilateral uterine artery moderate resistance blood flow.② The functional uterine artery PI (219±078) was lower in group C than in the non-functional side (287±062), the difference was statistically significant(t=456,P<005); the bilateral uterine arterial PI in group A,B and the control group had no significant difference(t=138,221,0.94,P>005). The ΔPI (1934±2253) in group C was significantly higher than that in the control group(312±1574),and the difference was statistically significant(t=542,P<005); there was no significant difference in ΔPI when the group A and B compared with the control group(t=142,1.74P>005).③ Taking the sensitivity as the ordinate and 1-specificity as the abscissa, the ROC curve of ΔPI was made. The area under the curve was 0715. When the uterine artery ΔPI>1888 %, the sensitivity and specificity of the diagnostic TP were the highest, respectively 5625 % and 8223 %. ConclusionThe early TP embryo vigor and the combination of gestational corpus luteum may affect the bilateral uterine artery PI. The measurement of bilateral ΔPI has certain clinical value for early TP diagnosis.
