title: [Posterm pregnancy].
abstract: This review presents the up-to-date information from published resources on the issue of Posterm pregnancy (Medline, Cochrane Database, ACOG, RCOG, SOGC) and complements the presented guidelines. The most of resources are using the term "postterm pregnancy" for pregnancy reaching or exceeding 42+0 weeks and days of gestation, while late pregnancy is defined as a period in between 41+0 and 41+6.The exact determination of gestational age is necessary for exact diagnosis and appropriate management of late and postterm pregnancy, because these pregnancies have increased risk of perinatal morbidity and mortality.
