The Research Of Uterine Endometrial And Ovarian Sonographic Hemodynamic Characteristics On Recurrent Spontaneous Abortion

Objective:(1) To explore uterine and ovarian sonographic findings and the hemodynamic characteristics by the transvaginal color doppler sonography in women with recurrent spontaneous abortion.(2)To compare the differrence between group with recurrent spontaneous abortion and control group in the sonography of uterine endometrial and ovarian hemodynamic characteristics, to further make a clinical transvaginal color doppler sonographic guideline in the diagnosis and differential diagnosis of recurrent spontaneous abortion.Method(1)Fifty patients were enrolled this study, and they were divided into two groups.The case group included 20 patients with recurrent spontaneous abortion, the control group included 30 patients who were nomal producted outpatient and randomized selected from our hospital gynecologic clinic during period from February 2010 to February 2011(2) TVCDS was performed regularly on two groups, and observed endometrial thickness, echogenicity type, ovarian size and echogenicity. Application of color doppler technique displayed clearly endometrial spiral artery and ovary artery flow, and hemodynamic parameters (peak-systolic velocity, end-diastolic velocity, resistance index, pulsatility index) were measured by PW.(3) The control group was regarded as reference, and compared TVCDS parameters differences between two groups. If P<0.05, the difference was statistically significant.Results(1) By using TVCDS,endometrial thickness, endometrial echogenicity, uterine and ovary artery were able to observed clearly.and some hemodynamic parameters such as uterine artery, endometrial artery and ovary artery, could be measured successfully.(2) The endometrial thickness of the contrl group was significantly thicker than that of the case group, and its echo structure was also displayed more clearly.(3)The control group had faster endometrial and ovary artery peak-systolic velocity (PSV), end-diastolic velocity (EDV) than the case group. However, The case group had higher endometrial resistance index (RI) and pulsatility index (PI) and ovary arteryscores resistance index (RI) than the control groupConclusionAs a non-invasive medical examine methods, TVCDS is a reliable medical imaging method in diagnosis of disease in obstetrical and gynecological. And TVCDS can provides a new diagnostic and prognostic evaluation through measureing uterine and ovarian hemodynamic parameters in diagnosis of RSA.
