A Study for Blood Flow Hemodynamics in Uterine Disease by Endovaginal Color Doppler Ultrasonography

Purpose To diagnose uterine disease early with the blood flow information summed up by endovaginal color Doppler in past ten years. Methods The blood flow characteristics such as degree of color imaging, morphology of velocity waveforms and hemodynamic parameters in 101 normal reproductive women. 105 normal early pregnant women and 219 patients who had been proved by histopathology were observed by endosavaginal color Doppler ultrasound (U.S.A Sequoia 512). Results ①The blood flow of uterine several arteries in normal women were all detected well, especially in early pregnancy. ②In incomplete abortion, if fluff tissue still lived, abnormal spiral artery whose peak systolic velocity was lower than in normal early pregnancy were seen. ③In invasion mole and choriocarcinoma, uterine several arteries were wider. Blood antra were detected in uterine wall and resistance index were lower than 0.4(RI0.4). ④The adenomyosis became bigger. Uterine corpus was rounder and blunter. Flowing was abundant, but went in order. ⑤Endometrial polyp demonstrated uniform hyperechogenicity of the uterine cavity and there was a little flow in polyp. Submucous myoma was uniformly hypoechoic and cricoid flow encircle it. In endometrial carcinoma,endometrium wrer wide. Flowing became much more discord and resistance index were lower than 0.4(RI0.4). Conclusion Uterine leison can be diagnosed accurately. It is helpful to clinic.
