The need for clearance surgery for pre-eclampsia miscarriage with a large pile of flesh should be determined by the specific examination results, because some patients with pre-eclampsia miscarriage can have a complete or incomplete miscarriage, and it is also possible to continue intrauterine pregnancy through fertility preservation treatment. After a large pile of flesh is discharged from a pre-eclampsia miscarriage, you should promptly go to the gynecological department of the hospital for ultrasound, blood HCG and progesterone to check the intrauterine condition. If the ultrasound shows that the miscarriage is complete and there is no residue in the uterus, it is a complete miscarriage and does not need to be cleared. If the ultrasound shows that there is residue in the uterus and the abortion is not complete, it is an incomplete abortion and a curettage is required. Patients who have undergone curettage are advised to go to the gynecology department of the hospital for a review after one week to avoid incomplete abortion or intrauterine residues and to pay attention to local hygiene of the vulva to avoid infection of the uterus by pathogens. For patients after the operation, they should ensure sufficient rest and nutrition, avoid sexual intercourse for one month, and forbid spicy, greasy, cold and stimulating food.
