Várias técnicas foram propostas anteriormente, mas gradientes residuais importantes foram observados, assim como há o inconveniente da ligadura definitiva da artéria subclávia esquerda. Nesta série, foram selecionados apenas pacientes com hipoplasia proximal e distal do arco aórtico. A definição de hipoplasia do arco aórtico seguiu os critérios de Moulaert, segundo os quais o arco aórtico é considerado hipoplásico quando seu diâmetro atinge 50% do diâmetro da aorta ascendente. Métodos: Entre janeiro de 2005 e julho de 2006, nove neonatos com coarctação aórtica e hipoplasia do arco aórtico foram submetidos a uma nova abordagem cirúrgica para correção do defeito. para correção da coarctação aórtica com hipoplasia do arco aórtico. RESUMO Objetivo: Estudar a viabilidade técnica e resultados imediatos da modificação técnica proposta por Caliani et al. Conclusion: Despite the small number of cases and the short follow-up, this technique modification may be an excellent option for the treatment of this complex situation. Up to now, there were no cases of recoarctation or medullary neurological lesions. Results: There were no perioperative or late deaths. The aim of this study is to describe a new surgical technique that includes left posterolateral thoracotomy, wide mobilization of descending aorta with occlusion of the first two intercostal branches, transection of the left subclavian artery at its base, wide resection of the hypoplastic area and the surronding regions of the ductus arteriosus end-to-end anastomosis between the aortic arch and descending aorta, with 7-0 PDS thread and reimplantation of the subclavian artery into the left carotid artery with side-to-end anastomosis. Many techniques were previously used, but significant residual gradients were observed, as well as the incovenience of definitive occlusion of the left subclavian artery. In this study, only patients with proximal and distal aortic hypoplasia were selected. The definition of aortic arch hypoplasia according to Moulaert's criteria is an aortic arch with a diameter that is less than 50% of the diameter of the ascending aorta. Methods: Between January 2005 and July 2006, nine newborn patients with aortic coarctation and significant aortic hypoplasia were selected, and underwent a new surgical approach in order to correct this aortic defect. for correction of aortic coarctation and aortic arc. ABSTRACT Objectives: To study technical feasibility and early results of the technical modification suggested by Caliani et al.
