Abstract: The value of three-dimensional ultrasound in the early diagnosis of intrauterine adhesions was explored in this paper. A total of 110 patients with suspected intrauterine adhesions were selected and given three-dimensional vaginal ultrasound and hysteroscopy. Finally, 72 cases were diagnosed as intrauterine adhesions. The proportion of pregnancy times ≥ 2, abortion times ≥ 2 and curettage times ≥ 2 in patients with intrauterine adhesions were significantly higher than those in patients with normal uterine cavity (P<0.05). The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of three-dimensional vaginal ultrasound in the diagnosis of intrauterine adhesions were higher than 80.00%. The Kappa value of three-dimensional ultrasound and hysteroscopy was 0.797, P<0.05. The endometrial volume (V), vascularization index (VI), flow index (FI), vascularization flow index (VFI) and endometrial thickness (ET) of patients with moderate to severe adhesions were significantly lower than those of patients with mild adhesions (P<0.05). The area under the ROC curve of moderate and severe adhesion predicted by V, VI, FI, VFI and ET was high, P< 0.05. Three-dimensional ultrasonography has good application value in the early diagnosis of intrauterine adhesions and the degree of adhesions, which is worthy of clinical use.
