Stage-by-stage correction of aortic coarctation in low-weight newborns (first experience)

Abstract

Aortic coarctation in low-weight (less than 2.2 kg) and premature newborns with comorbid conditions is still a current problem of neonatology and cardiac surgery. The closure of the patent ductus arteriosus and the inability to maintain its functioning with prostaglandin medication leads to fatal complications due to a violation of systemic perfusion. Surgical intervention in this group of patients has extremely high risks and unsatisfactory results. In such situations, stage-by-stage correction is a promising direction. Stenting of aortic coarctation allows restoring hemodynamics at the level of the aortic isthmus with minimal risks. In the inter-stage period, it becomes possible to treat comorbid conditions and prepare a patient for radical correction.
