The treatment of gravida is as follows: 1. Remove the contents of the uterine cavity Once the gravida is diagnosed, it should be removed in time. The advantage of this method is that the operation time is short, the bleeding is low, and the risk of perforation is rare, so it is safer. As the uterus is large and soft, it bleeds more during the operation and is also prone to perforation, so the uterus should be aspirated under fluid and blood preparation. The cervical canal should be fully dilated, and a large suction tube should be used for suction as much as possible to avoid blocking the lumen of the canal with the suction material often and affecting the operation. After the uterus has shrunk, the uterus should be scraped gently, and each scraping must be sent for histological examination, and the tissues in the uterine cavity and near the implantation site should be selected and sent for examination. The use of intravenous contractions during surgery can reduce bleeding and uterine perforation, but the drug needs to be given after the uterine orifice is enlarged to prevent trophoblast cells from pressing into the blood sinuses of the uterine wall and prompting pulmonary embolism and metastasis. In cases where the uterus is larger than 12 weeks of gestation, it is difficult to completely remove the staphylococcal tissue in a single operation and another curettage can be performed a week later. During the procedure, a very small number of patients may have a large number of trophoblast cells enter the uterine blood sinus and enter the pulmonary artery with the blood flow, resulting in pulmonary embolism and acute respiratory distress or even right heart failure. In severe cases, the patient may die. 2. Treatment of ovarian flavinized cysts After the removal of the gravida, the flavinized cysts can naturally subside without treatment. If acute reversal occurs, surgical exploration is required, and the cysts can be removed by laparoscopic aspiration of the cysts in each room, and the cysts can be reduced and reset naturally without surgical excision. If necrosis occurs after a long period of torsion, adnexal resection on the affected side is required. 3.Hysterectomy Hysterectomy alone can only remove the risk of staph invasion into the myometrium locally and cannot prevent the occurrence of extra-uterine metastasis, so it is not routinely treated. Total hysterectomy is feasible for those who are older than 40 years old, have high-risk factors and have no fertility requirements, and both ovaries should be preserved. If the uterus exceeds the size of 14 weeks of gestation, aspiration of the gravid tissue before removal of the uterus should be considered. Regular follow-up should be required after surgery. 4. Prophylactic chemotherapy Whether to give prophylactic chemotherapy while removing the uterine contents has been controversial. It is generally believed that prophylactic chemotherapy can be considered for patients with malignant tendency and difficult follow-up, and a course of single-agent chemotherapy, such as methotrexate, fluorouracil or vincristine, is usually used, with chemotherapy starting three days before uterine removal if possible. In partial gravida, prophylactic chemotherapy is not usually given.
