Abstract: In this article, with three-dimensional transvaginal ultrasound (3D-TVS), the changes of uterine volume and blood flow in patients with intrauterine adhesions were observed. 68 cases of intrauterine adhesion from November 2016 to November 2018 were included as the observation group, and 68 healthy women who came to our hospital for physical examination during the same period were selected as the control group. All of them underwent 3D-TVS examination in the middle and late menstrual cycle, and the sensitivity and specificity were observed with the pathological diagnosis as the gold standard. At the same time, the changes of 3D-TVS parameters such as endometrial volume (EV), blood flow index (FI), blood flow index (VFI) and intimal vascular index (VI) in the two groups were compared, and the changes of the above parameters in patients with different levels of intrauterine adhesion were compared. Among 68 cases confirmed by pathology, 64 cases were diagnosed by 3D-TVS, including 21 cases of type Ⅰ, 31 cases of type Ⅱ, 9 cases of type Ⅲ and 3 cases of type Ⅳ. The sensitivity of 3D-TVS was 92.65%, the specificity was 98.53%, the accuracy was 95.59%, the positive predictive value was 98.44%, the negative predictive value was 93.06%, the kappa value was 0.91. The EV, FI, VFI and VI in the observation group were significantly lower than those in the control group. EV in type Ⅰ was significantly higher than that in type Ⅱ, Ⅲ and Ⅳ; EV in type Ⅱ was significantly higher than that in type Ⅲ and Ⅳ (P<0.05); EV in type Ⅲ was significantly higher than that in type Ⅳ; VFI and VI of type Ⅰ were significantly higher than those of type Ⅲ and Ⅳ. The above results confirmed that 3D-TVS had an important value in evaluating the changes of uterine volume and blood flow in patients with intrauterine adhesions.
