For abortion surgery for patients with scarred pregnancy, the gestational sac is usually removed with an electrosurgical knife under hysteroscopy, and a small amount of bleeding can be stopped with an electrosurgical knife under direct vision. A suction tube is used to scrape the uterine lining in a circle, and a roughness in the uterine wall is sufficient, which is conducive to uterine contraction and reduces the occurrence of intraoperative and postoperative bleeding. Women suffering from scarred pregnancy mainly because the gestational sac grows at the scar, if the conventional suction tube is used to suck out the gestational sac, it may lead to perforation of the uterine wall, hemorrhage during the operation, and serious life-threatening situation. If the gestational sac is found to be more firmly bonded to the uterine wall by ultrasound during preoperative evaluation, or if there is implantation, and there is a higher chance of intraoperative hemorrhage, uterine artery embolization can also be done prior to the surgery to reduce bleeding before the surgery.
