FIELD: medicine.
SUBSTANCE: invention refers to medicine, particularly to obstetrics and foetal surgery. With underlying premedication and sedation, an intravenous catheter is inserted for continuous intraoperative tocolysis of a pregnant woman. Diagnostic cordocentesis with blood sampling and subsequent administration of a muscle relaxant to a foetus is performed under ultrasound control. Fentanyl is administered in amount of 10 mcg/kg of body weight for the purpose of anaesthesia. If the target haemoglobin value in the foetus is more than 100 g/l, the vessels feeding the sacrococcygeal teratoma are laser coagulated. Anterior abdominal wall and uterine wall are punctured with 18G mm needle. Then the mandrel is removed and a laser fibre is inserted into the needle lumen. Under ultrasound control with the help of laser fibre of 400 mcm with radiation of power of 60 W, arterial intratumoural vessels of sacrococcygeal teratoma are coagulated. State of blood flow in the sacrococcygeal teratoma is controlled by colour Dopplerometry. If foetal haemoglobin is less than 100 g/l, intrauterine intravascular blood transfusion is performed before laser coagulation of arterial intratumoural vessels of sacrococcygeal teratoma. Surgical manipulation is followed by ultrasonic monitoring of foetal heartbeat, blood flow in umbilical artery, blood flow in sacrococcygeal teratoma. On the next day after the operation, repeated ultrasonic examination is performed.
EFFECT: method enables minimally invasive correction of intrauterine sacrococcygeal teratoma with exophytic growth, arresting cardiovascular insufficiency and non-immune dropsy in foetus, prolonging pregnancy, preventing perinatal loss.
