Causes of incomplete uterine aspiration during abortion

Artificial abortion, also known as artificial abortion, may cause a variety of complications during and after the operation, such as artificial abortion complex reaction, uterine perforation, postoperative infection, postoperative bleeding, missed suction and incomplete uterine suction, etc.

Among them, if some pregnancy tissue remains in the uterine cavity, bleeding lasts more than 10 days after surgery, there is too much bleeding, or there is a lot of bleeding after bleeding stops, it should be considered as incomplete uterine aspiration. B-ultrasound examination is helpful for diagnosis. Its occurrence is related to factors such as unskilled operator skills, excessive uterine curvature and uterine malformation, including:

Uterine malformations: Common uterus include double uterus, bicornuate uterus, complete or incomplete septate uterus. When the gestational sac implants in one side of the uterine cavity or uterine horn, it is easy to cause embryo retention.

Uterine fibroids complicated with pregnancy: If uterine fibroids protrude into the uterine cavity, especially fibroids in the lower segment of the uterus, it will hinder surgical operations and result in residual embryos.

Scarred uterus: After cesarean section, the uterine incision adheres to the abdominal wall, causing the uterus to be pulled upward, the uterine body to bend backward, and the cervix to rise, making it difficult to expose; or the gestational sac is implanted in the scar of the lower uterine segment, and during surgery, due to concerns about uterine perforation, incomplete uterine aspiration may occur.

Excessive uterine flexion: If the uterus is excessively anteroflexed or retroflexed, the probe or suction tube may not reach the uterine fundus, which may easily lead to incomplete suction.

Operator's reasons: The operator is unskilled or has a weak sense of responsibility, does not master the key points of abortion, and performs the operation without carefully checking whether the sucked out embryonic tissue is consistent with the month of menopause, which may lead to incomplete abortion.
