Abstract:
Objective To explore the efficacy of transvaginal color Doppler sonography(TV-CDS)in the diagnosis and differential diagnosis of cornual pregnancy.Methods The characteristics of gray-scale and color Doppler ultrasonography of 30 patients with cornual pregnancy confirmed by surgery and pathology,were studied retrospectively.The position,size,figure,echogenicity and vascular pattern of the pregnancy tissue were evaluated,and the resistance index was calculated.Results The 30 patients were classified into two groups:group A with typical gestational sac and group B with abnormal mass in the area of corner.The overall diagnostic accuracy for these patients was 43.3%(13/3)and classified as 90%(9/10)accuracy for group A and 20%(4/20)for group B.Among the 17 patients who were misdiagnosed or diagnosed unclearly by TV-CDS,one patient in group A was misdiagnosed as a normal pregnancy,11 patients in group B were misdiagnosed as gestational trophoblastic disease and the rest 5 patients in group B were diagnosed unclearly.Conclusions TV-CDS is useful for differential diagnosis of cornual pregnancy.The cornual pregnancy with abnormal mass is usually misdiagnosed,and therefore clinical features and laboratory data should be fully evaluated for its diagnosis.
