Combined Use of Cerclage, Obstetric Pessary, and Micronised Progesterone in Recurrent Miscarriage

Abstract

Over the past years, the rate or preterm birth in Russia has increased from 4.3% in 2012 to 4.2% in 2014 and 4.1 in 2016 [1]. Preterm birth and prematurity are the leading global cause of neonatal death and second leading cause of death in under-fives, after pneumonia [2]. Approximately 5% of preterm births occur before 28 weeks of pregnancy, 15% between 28-31 weeks, 20% at 32-33 weeks, and 60-70% at 34-37 weeks [3]. Preterm birth is associated with nearly 75% of perinatal mortality cases [4,5], and surviving infants are often at a higher risk of disability, including learning difficulties and vision and hearing impairment [2].
