Main Causes and Outcomes of Very Early Preterm Births

Objective: to establish the main causes and outcomes of preterm pregnancy in the period of 22-276 weeks of gestation. Material and methods. A retrospective study of 100 cases of very early preterm birth (VEРB) was conducted. Results. VEРB more often occurred at the age of 20-29 years in multipregnant women whose anamnesis was aggravated by miscarriage and prematurity, perinatal losses. A high risk of developing pregnancy complications leading to VEРB was IDA (78.0%), pathology of the urinary tract (45.0%), and hypertension (31.0%). The survival rate of newborns up to 25 weeks of gestation was 3.7%, then it increases and by the 27th week it reaches 53.3% (M±m=31.9±4.4%).
