What should be done if a medical abortion is incomplete?

Although current induced abortion procedures are relatively simple and safe, some patients—due to concerns about privacy and fear of others discovering their pregnancy—opt for unlicensed or small clinics for the procedure. This significantly increases the risk of incomplete abortion (i.e., retained products of conception). So, what should be done if an abortion is incomplete?

How to Manage an Incomplete Abortion

Promptly visit a hospital for a transvaginal ultrasound examination to confirm the presence and extent of intrauterine retained tissue. Based on the findings, your healthcare provider will determine whether a second uterine evacuation (i.e., repeat curettage) is necessary.

Nausea and vomiting commonly occur during early pregnancy. If the abortion is complete, these symptoms typically subside. However, if the abortion is incomplete, such symptoms may persist. Incomplete removal of fetal tissue from the uterine cavity can trigger strong, paroxysmal uterine contractions postoperatively, resulting in severe, often unbearable abdominal pain. After a successful abortion, vaginal bleeding is usually minimal and gradually decreases until it ceases entirely. In contrast, with an incomplete abortion, bleeding may initially decrease but then suddenly increase—or continue unabated—indicating a serious complication requiring immediate medical attention.

Moreover, retained embryonic tissue impedes normal uterine involution, predisposing the patient to various gynecological infections. This may manifest as abnormal vaginal discharge, sometimes accompanied by pruritus. Uterine infection may further cause fever and tenderness upon pelvic examination.

A follow-up transvaginal ultrasound must be performed one month after the abortion to confirm complete evacuation. If residual tissue remains, prompt uterine evacuation is essential—delaying treatment is not advisable.

First, undergo a color Doppler ultrasound to assess the volume and location of retained tissue. Management options depend on the amount of residue: - For minimal residual tissue, pharmacologic management—including blood-activating and stasis-resolving medications—may promote spontaneous uterine contraction and expulsion of remaining tissue. - For larger amounts of retained tissue, prompt surgical uterine evacuation is mandatory. Postoperatively, a short course of antibiotics is recommended to prevent infection. Failure to perform timely repeat curettage not only risks persistent hemorrhage but may also lead to complications such as endometrial or tubal pathology—including tubal obstruction—that could impair future fertility.

Finally, carefully select a reputable medical facility for the repeat procedure to avoid compounding physical and psychological distress. Adhere strictly to postoperative care guidelines, including adequate nutritional support, to facilitate optimal recovery.
