TV-CDFI用于观察子宫腺肌病月经周期子宫内膜血流变化的研究

Study on blood stream of endometrium of the adenomyosis during menstrual cycle by transvaginal color doppler flow image

目的观察子宫腺肌病(AM)患者月经周期中子宫内膜血流变化规律与特点。方法应用经阴道彩色多普勒超声(TV-CDFI)分别于月经周期的卵泡早期、卵泡成熟期、黄体中期、黄体晚期观测子宫腺肌病患者及健康生育期妇女螺旋动脉显示率、彩色多普勒图像特点及阻力指数(RI)。结果 AM患者螺旋动脉在月经各个时期全部显示清晰,彩色多普勒图像特点变化不明显,RI卵泡早期偏高,卵泡成熟期和黄体中期居中,黄体晚期偏低,但不同时期间差异无统计学意义。健康生育期妇女螺旋动脉在月经不同时期显示率不同,彩色多普勒图像特点不同,RI呈周期性变化,不同时期间差异有统计学意义。卵泡早期显示率最低,RI最高;卵泡成熟期显示率升高,RI降低;黄体中期显示率进一步升高,RI最低;黄体晚期显示率最高,RI略有上升。结论 AM患者多伴有子宫内膜增生过长,螺旋动脉超声检出率较健康生育期妇女明显增加。AM患者月经周期中螺旋动脉血流动力学无明显周期性变化,RI较健康生育期妇女升高。

Objective To observe blood stream of endometrium in menstrual cycle of adenomyosis patient.Methods With transvaginal color doppler flow image （TV-CDFI）,measured display ratio,color doppler feature and resistent index （RI） ratio of helicine artery of adenomyosis patient and procreative women in the follicle growth phase,follicle maturation phase,midluteal phase and luteal advanced phase.Results Helicine artery were clearly displayed in different period of menstrual cycle,RI in early follicular phase were partial high,RI in mature follicle phase and midluteal phase were mediately,RI in late luteal phase were partial low,but there was no significant difference.The display ratio of helicine artery was different in different period.RI displayed a periodic change.There was significant difference in different period.In early follicular phase the display ratio was the lowest,RI was the highest;In mature follicle phase the display ratio improved,RI degraded;In midluteal phase the display ratio improved more,RI displayed lowest;In late luteal phase the display ratio was the highest,RI displayed to rise a little.Conclusion Adenomyosis patient is more accompany with excess endometrial hyperplasia,helicine artery of it is more easier displayed by TV-CDFI compare to women in healthy period of duration.RI of adenomyosis patient’s helicine artery displayed no periodic change in menstrual cycle,it is higher than that of women in healthy period of duration.
