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. Diagnostic cordocentesis with blood sampling and subsequent administration of a muscle relaxant to a foetus is performed under ultrasound control. If the target haemoglobin value is more than 100 g/l, the vessels feeding the chorioangioma are laser coagulated. An anterior abdominal wall and uterine wall are punctured with needle 18G mm, then a mandrin is removed and a laser fibre is inserted into the lumen of the needle. Fetoscopy is used to coagulate all vessels feeding the chorioangioma with the help of laser power of 60 W and laser fibre 400 mm to complete blood flow termination. If foetal haemoglobin is less than 100 g/l, intrauterine intravascular blood transfusion is performed before laser coagulation of vessels feeding the chorioangioma. Surgical manipulation is followed by ultrasonic monitoring of foetal heartbeat, blood flow in umbilical artery, in middle cerebral artery, and decrease of blood flow in chorioangioma is registered. On the next postoperative day, repeated ultrasonic and Doppler studies are performed.
EFFECT: method enables minimally invasive arrest of manifestations of non-immune dropsy in a foetus with underlying chorioangioma of angioblastic type, prolongation of pregnancy, prevention of development of complications and unfavourable outcome in newborns.
