Perfil clínico e cirúrgico dos pacientes submetidos a cirurgia de Norwood em um hospital terciário de Salvador-Bahia

Abstract

Introduction: The Norwood procedure is a highly complex intervention for the treatment of Hypoplastic Left Heart Syndrome, associated with high morbidity and mortality rates. This study aimed to describe the clinical profile, complications, and outcomes of patients undergoing this procedure at a reference hospital in Brazil. Methods: This observational, descriptive, and retrospective study included all patients who underwent the Norwood procedure at Hospital Ana Nery between 2014 and 2023. Data were collected from medical records. Results: The sample comprised 20 patients, with a median age of 13 days (IQR: 8-29), of whom 50% were female. The main complications observed were cardiopulmonary arrest (40%), ventricular dysfunction (20%), and bleeding (35%), while intraoperative mortality reached 55%. No statistically significant associations were identified between clinical variables and outcomes. Extracorporeal circulation time was longer in recent years (2019-2023) but had no impact on clinical results. Conclusion: The findings highlight the high mortality and morbidity associated with the Norwood procedure, reflecting the severity and complexity of its management. Future studies with larger sample sizes and long-term follow-up are needed to enhance the understanding of factors associated with outcomes and to propose strategies to reduce complications and improve survival rates.
