Scar pregnancy is a type of ectopic pregnancy, and it is recommended to register with a family planning department, gynecology, obstetrics or reproduction department, or other related departments. A scar pregnancy is a ectopic pregnancy in which the fertilized egg is deposited in the scar of the uterine incision from a previous cesarean section. This is a dangerous condition that can lead to rupture of the incision as the gestational sac grows larger, endangering the life and health of the woman. Since most cesarean section scar site pregnancies are dangerous, once diagnosed, women are advised to consider terminating the pregnancy without forcing the pregnancy to stay alive to avoid health consequences. If the pregnancy is terminated, the main departments to be registered are family planning and gynecology; if there is a need for abortion preservation, they can temporarily register with gynecology, obstetrics or reproduction and other related departments. In clinical practice, it is recommended that people with scarred pregnancies go to regular hospitals in time and choose the appropriate treatment method under the guidance of specialists to avoid adverse consequences.
