Application value of transvaginal ultrasound combined with abdominal B ultrasound in the diagnosis of ectopic pregnancy

Objective To investigate the application value of transvaginal ultrasound combined with abdominal B ultrasound in the diagnosis of ectopic pregnancy, and provide guidance for early diagnosis of ectopic pregnancy.Methods The clinical data of 106 patients confirmed by surgery or conservative treatment as ectopic pregnancy in our hospital during December 2011 to December 2013 were analyzed retrospectively. All patients underwent transvaginal ultrasound and abdominal ultrasound to observe the abnormality in ovaries and para-uterine area, and then the positive rate and misdiagnosis rate of ectopic pregnancy were compared between patients examined by transvaginal ultrasound, abdominal B ultrasound and combined ultrasound. Results The detection rate of yolk sac, fetal bud, cardiac and pelvic effusion in abdominal B was significantly lower than that in transvaginal sound(P0.05). 101 cases of ectopic pregnancy were diagnosed by the combined ultrasound, where the diagnosis rate and misdiagnosis rate were95.28% and 4.72% respectively. Meanwhile, 79 cases of ectopic pregnancy were diagnosed by abdominal ultrasound alone, where the diagnosis rate and misdiagnosis rate were 74.53% and 25.47% respectively. There were 82 cases of ectopic pregnancy were diagnosed by transvaginal ultrasound alone with diagnose rate of 77.36% and misdiagnosis rate of 22.64%. There were statistically significant difference between combined ultrasound and transvaginal ultrasound or abdominal ultrasound alone(P0.05). However, there was no statistically significant difference between transvaginal ultrasound and abdominal ultrasound(P0.05). Conclusion The transvaginal ultrasound combined abdominal B can significantly improve the diagnosis effect of ectopic pregnancy, which provides a more convenient and efficient diagnostic tool with a higher accuracy for diagnosis. Therefore, it is worthy of clinical application.
