Abstract

Purpose

The objective of this study was to retrospectively assess whether the sonographic findings from transvaginal color Doppler ultrasound (TV-CDU) are helpful in the diagnosis of ectopic pregnancy.

Methods

Thirty-four patients who received surgery for ectopic tubal pregnancies were preoperatively evaluated using TV-CDU. The presence or absence of color vascularity within the ectopic masses was examined. The relationship between the presence or absence of blood flow in the tubal mass and the corpus luteum cyst, or the serum β-hCG values, was evaluated.

Results

Color vascularity within the adnexal mass was detected in 27 of 34 (79.4%) patients with ectopic pregnancies by TV-CDU. Color vascularity within the mass was observed in 18 of 24 (75.0%) patients with a questionable adnexal mass that had no obvious gestational sac in B-mode images. Moreover, color vascularity was seen in all four patients with a serum β-human chorionic gonadotropin (β-hCG) value of less than 500 mIU/ml. However, it was difficult to identify the blood flow of the adnexal mass in six of the nine (66.7%) patients with a corpus luteum cyst in the ipsilateral ovary. No relationship was observed between the serum β-hCG concentrations and the resistance indices, or the peak systolic velocity.

Conclusions

The detection of color vascularity by TV-CDU in patients with an ectopic pregnancy is helpful for diagnosis, especially for patients with either a questionable adnexal mass in B-mode images or lower serum β-hCG concentrations.
