Yesterday, we saw a report on the internet about a couple in Shandong who gave birth to quintuplets and the daily medical cost was more than 10,000 yuan, which is regrettable. 2, because the fertility center has the technology of fetal reduction, but the gynecology department does not have it, so she turned to our center; 3, after coming here, we learned that the patient had seen many fertility centers in Shanghai, but none of them accepted to do the fetal reduction surgery for her; 4, after our examination and inquiry, the last seen at 40 days of pregnancy was quintuplets, and 4 gestational sacs had fetal heart, so we decided to do the fetal reduction surgery at 50 days of pregnancy, and tried to reduce to 2 fetuses in one time, i.e. 4 -After careful preoperative preparation, we performed the reduction on January 6 under ultrasound, i.e. 4-2=2 fetuses, two of them were reduced and the other two fetuses were preserved.
