Results of surgical treatment and incidence of postoperative complications in the follow up period were analyzed using primary data and outpatient medical records of the children treated at Lviv Children’s Regional Hospital in the period of September 1999 – January 2016. Majority of the patients with Down syndrome underwent a two-stage surgical correction: pulmonary artery banding at the age of 2-3 months, followed by radical surgery at an older age (2-3 years) (p <0.05), while patients without chromosomal pathology were performed one-stage surgical correction. It was found that the hemodynamic features in children with complete AVCD without Down syndrome determine significantly higher need for reoperation (20.00 ± 8.00% versus 0%; p = 0.038). Radical surgical intervention does not provide complete correction of mitral valve insufficiency – in the long-term postoperative period, 100 % of children had varying degrees of insufficiency on the mitral valve: in particular, in 10.91 ± 4.20 % of mild stage (2+) and in 3.64 ± 2.52% – severe (3+). At the same time, the tricuspid valve insufficiency remained in 47.27 ± 6.73 % of the operated children, and the interventricular septum re-shunt was determined in 5.45 ± 3.06 % of the children. The obtained results prove the need for long term follow-up of children with surgically-corrected AVSD in order to diagnose the degree of insufficiency of mitral and tricuspid valves and to refer for re-operation in time.
