Restenosis Rate and Reinterventions after Aortic Arch Repair in Infants

The aim. This study aims to determine the reintervention rate in infantsundergoing aortic arch repair and analyze risk factors evaluate results of reinterventions.
 Materials methods. retrospective examines 445 infants with hypoplasia who under-went reconstruction between 2011 2019. included only patients two-ventricle physiology subsequent repair. Techniques for primary extended end-to-end anastomosis (n = 348), end-to-side 611), autologous pericardial patch 16).
 Results. overall mortality entire group was 3.3 %. Follow-up period ranged from 1 month 9.4 years (mean 2.8 ± 2.5 years). Restenosis at site identiϐied 47 (10.5 %) patients. Of these, 12 underwent surgical arch, 27 balloon angioplasty, 8 both methods were used. Freedom 89.4 % 1-year follow-up 87.5 4-year follow-up. most determining factorsfor restenosis related hypoplastic proximal body weight less than kg.
 Conclusions. Surgical treatment newborns is effective shows good immediate long-term results. Anatomical correction reobstruction level safe endovacular low incidence repeated interventions. Identified recurrent interventions help improve under year age.
