Accurate diagnosis of postabortal placental remnant by sonohysterography and color Doppler sonographic studies.

The decision whether to perform uterine curettage for postabortal bleeding depends on the ability to demonstrate placental remnants in the uterine cavity. However, diagnosis of postabortal trophoblastic residua by conventional ultrasonography may be inconclusive. We report our experience with the use of combined sonohysterography and color Doppler to demonstrate a placental polyp after early pregnancy termination.
