变换体位经阴道超声对宫外孕未破裂型与妊娠黄体囊肿鉴别诊断的价值

摘要

Objective To study the Value of changing position of transvaginal color Doppler ultrasound in differential diagnosis of unruptured ectopic pregnancy and pregnancy luteal cyst,improve the detection rate of early ectopic pregnancy.Methods To applicate changing position of transvaginal color Doppler ultrasound in 44 patients with unruptured ectopic pregnancy and 25 pregnancy luteal cyst nodules with the size,thickness of rings,ring-wall echo,blood flow distribution characteristics,vascular resistance index,and comparative observation of ovary position relationships after changing posture.Results 27％ unruptured ectopic pregnancy nodules were rich in peripheral blood flow signal(12/44),73 ％ blood flow signals were limited (32/44) ; 80 ％ pregnancy luteal cyst nodules rich in peripheral blood flow signal (20/25),20％blood flow signals were limited (5/25).Two group comparison of the distribution of blood flow signal difference was statistically significant (P＜0.05).Unruptured ectopic pregnancy blood flow spectrum of RI average (0.69±0.08),pregnancy luteal cyst blood flow spectrum of RI average (0.50±0.10),two group comparison of RI value differences were statistically significant (P＜0.05).Of unruptured ectopic pregnancy after changing position,89％nodules and the ipsilateral ovary position of changes (39/44),none of the pregnancy luteal cyst changed after changing position(0/25),statistically significant difference exited (P＜0.01).Conclusions Transvaginal color Doppler on unruptured ectopic pregnancy and pregnancy [uteal cyst identification has important clinical applications.%目的 探讨变换体位经阴道彩色多普勒超声鉴别宫外孕未破裂型与妊娠黄体囊肿的价值,提高宫外孕的早期检出率.方法 应用变换体位经阴道彩色多普勒超声对比分析44例宫外孕未破裂型与25例妊娠黄体囊肿的大小、环壁厚度、环壁回声、血流分布特征、血流阻力指数、变换体位后结节与卵巢位置关系进行对比观察.结果 宫外孕未破裂型结节周边血流信号丰富27％ (12/44),血流信号不丰富73％ (32/44);妊娠黄体囊肿周边血流信号丰富80％ (20/25),血流信号不丰富20％ (5/25),两组血流信号分布的比较差异有统计学意义(P＜0.05).宫外孕未破裂型结节血流频谱RI平均0.69±0.08,妊娠黄体囊肿血流频谱RI平均0.50±0.10,两组RI值的比较差异有统计学意义(P＜0.05).宫外孕未破裂型结节在变换体位后,与同侧卵巢位置关系改变89％ (39/44);妊娠黄体囊肿在变换体位后,与同侧卵巢位置关系未见改变(0/25),两组在变换体位后与卵巢位置关系改变的差异有统计学意义(P＜0.01).结论 变换体位经阴道彩色多普勒对宫外孕未破裂型与妊娠黄体囊肿的鉴别具有重要的临床应用价值.
