Total Anomalous Pulmonary Venous Connection: Surgical Outcomes and Risk Factors for Postoperative Pulmonary Vein Obstruction.

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.
