Factors that increase the risk of continuing the pregnancy beyond 40 weeks.

Abstract

At present, prolonged and postterm pregnancy represents a significant issue in obstetrics and gynecology. This is largely attributed to the increased occurrence of complications during labor, as well as pathological changes in the fetus, both of which contribute to heightened perinatal mortality rates. Depending on the literature, perinatal mortality can reach as high as 19%, while neonatal morbidity may approach 28%. These outcomes are often linked to the fetus's reduced ability to tolerate hypoxia, which stems from advanced maturation of the brain and diminished oxygen delivery due to dystrophic and regressive changes in the placenta. As a result, identifying risk factors associated with pregnancies extending beyond 40 weeks is of critical importance. Thus, postterm pregnancy should be recognized as a pathological condition influenced by various contributing factors. The aim of the study. Evaluate the factors of the risk of prolongation of pregnancy for more than 40 weeks according to a retrospective analysis of birth histories with this pathology.
