Abstract: ［Abstract］ Objective〖HTSS〗〓To explore the clinical evaluation and diagnostic value of transvaginal sonography on uterine cavity volume, blood flow in patients with intrauterine adhesion.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓A total of 64 cases of patients with gynecological uterine adhesion were selected as study group. And 60 cases normal female were selected as control group. They were examined by hysteroscopy during the middle and late menstrual cycle. The endometrial thickness, uterine cavity shape, internal flow and echo, 3D build endometrial database, uterine volume, vascularization flow index(VFI), flow index(FI), vascularization index(VI) of two groups were compared.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓There were totally 64 cases with uterine cavity adhesion in this study, including 20 cases of type I, radiographic images showed intrauterine small adhesion; 30 cases of typeⅡ, radiographic image showed intrauterine more than fibrous or membrane adhesion; 8 cases of type Ⅲ, radiographic images showed the uterus was narrow, the uterus extensive dense adhesion; 2 cases with type IV, radiographic image display for cervical adhesion; 4 cases radiographic images not showed intrauterine adhesions. The accuracy of transvaginal ultrasonography in diagnosis of intrauterine adhesions was 93.75%.The endometrial thickness of study group was significantly lower than the control group. The endometrial thickness of study group was inhomogeneity, echo heterogeneity. The uterine cavity shape is irregular. The threedimensional uterine cavity is irregular and the internal blood flow signals are sparse. The endometrium of the control group was clearly defined, echo was uniform, the threedimensional uterine cavity is regular in shape and triangular in shape, internal blood flow signals are abundant. The uterine volume, VFI，FI, VI of study group was significantly lower than the control group, the difference is statistically significant(P<0.05).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓The ultrasonic image of the patient showed that the volume of the uterus decreased and the parameters of the blood flow decreased. Transvaginal ultrasound can objectively evaluate the uterine volume and blood flow changes, and provide a reference value for clinical diagnosis, which is worthy of popularization and application.
