Abstract
Background: Three-dimensional transvaginal ultrasound (3D-TVUS) has recently been adopted in the gynecological sciences as it provides an accurate illustration of adhesions and the extent of cavity damage, and hence, can be used as an essential tool for the prognosis of intrauterine adhesions (IUA). This study aims to demonstrate whether preoperative 3D-TVUS features are relevant to ongoing pregnancy and live births in patients with IUA following hysteroscopic adhesiolysis (HA). Methods: From February 22, 2018, to October 31, 2018, a total of 401 patients with moderate to severe IUA and underwent HA were retrospectively enrolled. Preoperative 3D-TVUS diagnosed data and the patients' basic information were collected, and patients were followed up over 2 years after HA for reproductive outcomes. The correlation between each imaging variable and ongoing pregnancy or live birth was analyzed by binary logistic regression. Results: Among the 401 patients, 143 had live births, 41 patients had abortions, and 217 patients were infertile. Thick endometrium was found to be favorable for ongoing pregnancy (ongoing pregnancy group =5.4±1.95 mm, no-ongoing pregnancy group =4.7±2.24 mm, P=0.0095) and live birth (live birth group=5.6±1.92 mm, no-live birth group =4.7±2.20 mm, P=0.0029). Scar contraction was not conducive for pregnancy, while the lower segmentation was not a risk factor for ongoing pregnancy (P=0.0003). It also was a risk factor for ongoing pregnancy (P<0.0001) and live birth (P<0.0001) when the segmentation of the endometrial absence was mainly in the upper and middle segments of the uterine cavity. The area under the curves (AUCs) of the prediction model for ongoing pregnancy and live birth were 0.9116 and 0.8751, respectively, based on the meaningful variables above combined with other clinical characteristics. Conclusions: Preoperative 3D-TVUS features have a close correlation with ongoing pregnancy and live births in patients with IUA following HA, and can be applied for predicting ongoing pregnancy and live births in IUA patients post-HA. 2022 Quantitative Imaging in Medicine and Surgery.
