Clinical Value of Transvaginal Ultrasound in the Diagnosis of Tubal Pregnancy / 医学研究杂志

ABSTRACT

Objective To evaluate the value of transvaginal ultrasound in the diagnosis of tubal pregnancy.Methods The retrospective analysis was made according to transvaginal ultrasound inspection on 77 patients and their sonographic appearance and ultrasonic diagnosis of tubal pregnancy proved by surgery and pathology.Results The two-dimensional sonogram mainly showed the adnexal masses and the liquid area opaca in the pelvic cavity.The masses were divided into three typesgerm heart-beat type,gestational sac type,and uneven mixed mass type.According to distinctive two-dimensional sonographic appearance,the accuracy rates of transvaginal ultrasound in the diagnosis of rupture,nonrupture,and abortion tubal pregnancy were 87.23%,100%,and 34.62%,respectively.In combination with pelvic mass,indirect sign of effusion,and patient history,the accuracy rates of ultrasonic diagnosis in the above clinical classifications were 95.74%,100%,and 84.61%,respectively.The accuracy rate of the total ultrasonic diagnosis was 92.21%.Conclusions Transvaginal ultrasound has higher accuracy in the diagnosis of rupture and nonrupture tubal pregnancy,but it lacks distinctive sonographic appearance in the diagnosis of the majority of abortion tubal pregnancy,which is the main reason for affecting the accuracy of ultrasonic diagnosis of tubal pregnancy.
