How to prevent leakage during abortion

Missed aspiration is one of the possible complications during abortion surgery. It means that an intrauterine pregnancy is confirmed, but the embryo and villi are not aspirated during the operation. The cause of the disease is too small blastocyst, excessive uterine curvature, uterine malformation, etc. According to the cause of the disease, targeted preventive measures can be taken to reduce the incidence of missed aspiration.

1. The gestational sac is too small

If the gestational sac is too small, the patient can wait for a few more days and perform surgery when the gestational sac is slightly larger; the tension of the gestational sac is greater and it is more likely to cause suction leakage, so the scraped embryonic tissue should be carefully checked before the end of the operation.

2. People with excessive uterine curvature

If the uterus is over-flexed (such as anteroflexion or retroflexion), it can be corrected by two-handed reduction or traction of the cervix during surgery. If it cannot be reduced, it is best to perform the surgery under the guidance of B-ultrasound. If the above conditions cannot be met, it is necessary to check whether the villi are intact before the end of the surgery. If not, operate carefully until the surgery is successful.

3. People with uterine malformation

Common uterine malformations include didelphys, bicornuate uterus, complete or incomplete septate uterus, etc. If the equipment conditions permit, the surgical operation can be performed under the guidance of B-ultrasound. If the relevant conditions are not available, the surgeon should check the villi and decidua before the end of the operation. Patients with bicornuate uterus have more decidua. If no villi are seen or there are fewer decidua, the uterine cavity should be re-explored to avoid missed suction.

In addition to the above situations, one of the ways to prevent missed aspiration is for the operator to strengthen his sense of responsibility and perform the operation carefully.
