Total Anomalous Pulmonary Venous Connection: Surgical Outcomes and Risk Factors for Postoperative Pulmonary Vein Obstruction
摘要
Background: Total anomalous pulmonary venous connection (TAPVC) is a fatal congenital cardiac anomaly that requires urgent surgical intervention. The development of postoperative pulmonary vein obstruction (PVO) negatively impacts long-term survival. Objectives: The present study aimed to evaluate the surgical outcomes of TAPVC repair and risk factors associated with postoperative PVO. Methods: Patients who underwent primary TAPVC repair at our institute between 2004 and 2022 were retrospectively enrolled, and those with right atrial isomerism and single ventricle physiology were excluded. Factors associated with survival and postoperative PVO were analyzed. Results: A total of 116 patients were enrolled in the present study. The early mortality rate was 6.9%. Nineteen patients (16.4%) developed postoperative PVO within a median time of 59 days of the primary repair, of whom 10 were successfully relieved without any recurrent obstruction. In long-term follow-up, patients with postoperative PVO had significantly lower long-term survival rates than those without postoperative PVO [57.9%, 95% confidence interval (CI) = 34.8-79.5%; vs. 90.4%, 95% CI = 83-96.6% at 10 years, p < 0.001]. Risk factors for postoperative PVO development included lower body weight, younger age, preoperative mechanical ventilation, preoperative inotrope use, and emergency operation. Conclusions: Postoperative PVO was significantly associated with a higher long-term mortality rate after primary TAPVC repair, with the risk being higher in patients with critical preoperative status. The long-term outcome was good for patients in whom the obstruction was successfully relieved. Early detection and prompt intervention for postoperative PVO after TAPVC repair can improve overall survival in these patients.
