The diagnostic value of three-dimensional ultrasound for congenital uterine anomalies

Objective To investigate the diagnostic value of three-dimensioal(3D) ultrasonography for congenital uterine anomalies. Methods Fifty patients which were suspected to suffer congenital uterine anomalies were examined by two-dimensional(2D) ultrasonography and 3D ultrasonography and the results were compared. The sonographic features of uterine anomalies were illustrated. Results Among 50 cases,6 cases were diagnosed as didelphic uterus.,20 cases were subseptate uterus,8 cases were complete septate uterus,10 cases were bicornuate uterus,4 cases were arcuate uterus and 2 cases were single horn uterus. The accuracy rate of 3D ultrasound was 100%,while the accuracy rate of 2D ultrasound was 84%. Didelphic uterus appeared as two independent uteri. The fundal shape of septate uterus was basically normal,the endometrial cavity of subseptate uterus appeared Y shape,while that of complete septate uterus appeared V shape. The bicornuate uterus fundal depressed,the endometrial cavity appeared Y shape and the angle was bigger. The arcuate uterus shape was normal but the fundal endometrial was concave slightly. The single horn uterus shape was spindle,the endometrial cavity showed a single angular. Conclusion 3D ultrasonography can show the morphological structure of uterine cavity and the appearance of fundus, It is significantly superior to 2D ultrasonography in the diagnosis of congenital uterine anomalies and can be used as a simple,convenient and accurate diagnostic method.
