Morphometric analysis of the hemodynamic significance of patent ductus arteriosus in preterm infants

Abstract

The problem of children born with extremely low body weight (ELBW) remains relevant for specialists in perinatal medicine and pediatricians due to the presence of formidable conditions in most of them, which significantly affect health and further prognosis. One of these factors is the functioning of the patent ductus arteriosus (PDA). However, early diagnosis can reduce the adverse consequences for a premature baby. Echocardiography (EchoCG) is the procedure of choice for confirming the diagnosis and characterization of PDA. The purpose of the literature review is to analyze and summarize current and relevant information related to the morphometric analysis of hemodynamically significant PDA in newborns with ELBW. This literature review discusses the pathogenetic factors in the functioning of the arterial duct, the mechanisms of its influence on systemic hemodynamics, and describes the value of dynamic monitoring of echocardiographic parameters in preterm infants.
