What is leakage during abortion?

When the embryonic sac and main placental tissue are not seen during the abortion, only part of the decidual tissue or a very small amount of villi are sucked out. Although the embryo is disturbed, it fails to stop developing. This is called missed aspiration. Possible reasons for not sucking out the embryonic sac are: ① Due to the small gestational age, the menstruation is within 6 weeks, the embryonic tissue is small, and it is not sucked near the uterine cornu. ② The uterus is flexed and the suction tube does not reach the uterine fundus. ③ The pelvic examination estimates that the size of the uterus is smaller than the actual size. During the operation, the probe and suction tube did not reach the side where the embryo implants. ④ The fertilized egg has not yet reached the uterine cavity. ⑤ Uterine fibroids and pregnancy. The manifestation of missed aspiration is that there is still a pregnancy reaction after aspiration and the uterus is enlarged. When missed aspiration is found, close follow-up should be carried out, and the pregnancy should not continue. Another operation is often required. For those who do not see the embryonic sac during the operation, they should also be particularly alert to the possibility of ectopic pregnancy.
