Résumé
A coarctação de artéria pulmonar é comum em pacientes com atresia pulmonar. A correção tem sido com CEC e no período neonatal, quando influencia o desenvolvimento das artérias pulmonares e o prognóstico. Foram corrigidos três pacientes por esternotomia mediana com atresia pulmonar dependentes do ducto arterioso (PCA) sem uso de CEC. O PCA mantinha a saturação durante a confecção do Blalock Taussig na artéria pulmonar contralateral. Arterioplastia foi realizada com sutura de pericárdio autólogo com PDS 7-0 e saturação mantida pelo Blalock. Todos pacientes tiveram boa evolução e alta hospitalar com avaliação de controle demonstrando bom alargamento da área coarctada.
Pulmonary artery coarctation often happens in patients with pulmonary atresia. The correction has been usually performed using cardiopulmonary bypass and during the neonatal period, influencing pulmonary artery development and prognosis. Three patients with pulmonary atresia with PDA underwent correction using median sternotomy without cardiopulmonary bypass. The PDA maintained the arterial saturation during Blalock Taussig anastomoses upon the contralateral pulmonary artery. Arterioplasty was performed using an autologous pericardium with 7-0 PDS running suture and saturation was maintained by Blalock shunt. All patients presented good follow-up and where discharged with good enlargment of coarctation area.
