Abstract

Purpose

The purpose of this study was to evaluate the role of color Doppler imaging during sonohysterography in the diagnosis of residual trophoblastic tissue.

Methods

This prospective cohort study involved 25 consecutive women with clinical and sonographic signs of an echogenic intrauterine mass who were referred to the sonography unit of our institution for evaluation. All women underwent saline infusion sonohysterography with color Doppler sonographic evaluation. An operative hysteroscopy with histologic examination was performed in 17 cases.

Results

Thirteen women (group A) had sonohysterographic features suggestive of residual tropho‐ blastic tissue (ie, an echogenic intrauterine lesion not detached from the uterine wall after introduction of saline). The initial diagnosis was confirmed by histologic analysis in all cases. Blood flow was detected within the intrauterine mass in 6 (46%) of these 13 women; the resistance indices were low in all 6 cases (mean Β± standard error, 0.38 Β± 0.01). Twelve women (group B) had sonohysterographic findings negative for retained tissue, and no blood flow was detected within any of the intrauterine masses in this group (p < 0.05).

Conclusions

Our results confirm the potential role of color Doppler sonography in the initial diagnosis of residual trophoblastic tissue. The detection of color Doppler signals, especially with low‐resistance flow, within an intrauterine lesion should increase the confidence of the sonologist in the diagnosis of residual trophoblastic tissue.
