FIELD: medicine. ^ SUBSTANCE: patients in their 16 weeks of pregnancy initiated by ART methods are examined for fibrinogen levels, and chorion volume is calculated by formula: V =Ç/6êÖABC (cm3), where A is a maximum length, B is a maximum width, and C is a maximum thickness of the chorion measured by ultrasonic examination. Further, a prognostic index is calculated: F=1.35*FG-0.02*V-5.75, where FG is fibrinogen levels (g/l), V is chorion volume (cm3), const - 5.75. If the F value is less than 0, favorable prognosis for a foetus is considered, while F more than 0 shows a high probability of intrauterine growth retardation. ^ EFFECT: use of a method allows higher prediction accuracy of intrauterine growth retardation in the second trimester of pregnancy after auxiliary reproductive technologies. ^ 2 ex |
