Abstract:

Objective　To analyze the efficacy of three-dimensional vaginal ultrasound in the diagnosis of scar pregnancy (SP) classification. Methods　Sixty patients with SP treated at Haizhu District Women and Children Health Care Hospital from July 2020 to July 2023 were selected as the study objects. They were (31.52±4.27) years old. All the patients were examined by three-dimensional vaginal ultrasound. The results of surgical pathologic diagnosis were set as the gold standard. The diagnostic efficacy of three-dimensional vaginal ultrasound in the diagnosis of SP classification was explored. χ²  test was used. Results　SP was detected in 59 cases by three-dimensional vaginal ultrasound, and one case was missed, with a diagnostic accuracy of 98.33% (59/60) and a missed diagnosis rate of 1.67% (1/60). There was no statistical difference in the SP detection rate between three-dimensional vaginal ultrasound and surgical pathology (χ²=0.099, P>0.05). The coincidence rates of three-dimensional vaginal ultrasound in the diagnosis of the simple pregnancy sac type and uterine type were 100.00% (43/43) and 100.00% (11/11), and that of mixed mass type was 83.33% (5/6). There was no statistical difference in the detection rate of SP in different types between three-dimensional vaginal ultrasound and surgical pathology (χ²=0.067, P>0.05). The coincidence rates of type I and type Ⅱ were 100.00% (41/41) and 100.00% (10/10), and that of type Ⅲ was 88.89% (8/9). Conclusion　Three-dimensional vaginal ultrasound has a high diagnostic accuracy in SP classification, a high diagnostic coincidence rate for different SP classification and diagnostic image features, and a high diagnostic efficacy, so it is recommended to promote in clinical use.
