Abstract：Objective To study the ultrasonographic characteristics of vaginal bleeding after medical
abortion. Methods 300 cases of vaginal bleeding after medical abortion underwent trans-abdominal
and trans-vaginal color Doppler ultrasound examinations were divided into different types according
to the uterine size, shape, muscle layer echoes, uterine muscle layer flow, conditions in annex areas,
intrauterine echoes, endometrial echoes, endometrial thickness, endometrial boundaries, the size of the
intrauterine mass, boundaries between the mass and the surrounding normal tissues, clump echoes, blood
flow distribution and the spectrum characteristics of the internal mass and peripheral tissues. Results
Vaginal bleeding after drug abortion could be divided into 5 types, including uterine inertia type, simple
intrauterine residue type, intrauterine residue with infections, organized residue type and endometrial
repair barriers. Conclusion The ultrasonographic classification of vaginal bleeding after medical abortion
is helpful for clinicians to give ultrasonographic descriptions and dialectical therapies.
