I. Indications for surgery for mediastinum 1. 1-2 spontaneous abortions; including embryonic abortion, etc.; 2. Complete mediastinum: early surgery is recommended; 3. Age greater than 28 years, if the mediastinum is wide, active surgery is recommended: no need to wait for a history of spontaneous abortion before doing it! 4, combined with vaginal mediastinum: according to the patient’s will, it can be removed or partially removed; 5, if the mediastinum is found in the first half of menstruation, considering the wide mediastinum, combined with age and other factors (such as greater than 25 years old), hysteroscopic electrosurgery is recommended. Longitudinal surgery and anesthesia 1. hysteroscopic electrosurgery is the best surgical method; 2. ultrasound or laparoscopy can be chosen for monitoring; 3. no birth control device is placed after surgery and estrogen replacement therapy is not used; 4. anesthesia is mostly non-tracheal intravenous general anesthesia, and it is possible to eat and get out of bed more than 2 hours after surgery. When to get pregnant after longitudinal uterus surgery Pregnancy is possible 2-3 months after surgery. Perinatal management and active fetal preservation for those with a history of spontaneous abortion should not be taken lightly, as the mediastinum is only an anatomical factor and not the only cause of abortion, as there are still patients with spontaneous abortions or stillbirths after removal of the mediastinum! The purpose of surgery is to help the patient to finally have a healthy full-term baby; surgery can only increase the chances, not cause infertility, otherwise surgery would have no meaning! The above is my experience only and does not represent others.
