PurposeIn Nuss procedure for pectus excavatum (PE) after surgery for congenital heart disease (CHD), retrosternal adhesion may increase the risk of cardiac injury. This study aimed to explore different Nuss procedures and their implications for reducing the incidence of serious complications and improving surgical safety.MethodsWe retrospectively reviewed 49 cases (29 male and 20 female) of Nuss procedures for PE after surgery for CHD that were performed between April 2003 and December 2016. The median age was 5.8 years (range, 3.0-17.9), and the median Haller index was 4.6 (3.2-17.7). All patients were evaluated on their cardiac function and severity of PE by echocardiography and computed tomography scan, respectively. Three surgical procedures were used. Perioperative conditions were analyzed, including CHD type, interval between two operations, blood loss, operation time, hospital stay, complications, and postoperative results.ResultsAll 49 cases were completed successfully. Fourteen cases (28.6%) involved the standard three-incision thoracoscopic Nuss procedure, 30 cases (61.2%) involved the Nuss procedure assisted by a median sternum incision, and 5 cases (10.2%) involved the Nuss procedure with sternal suspension. The median interval between the CHD surgery and Nuss procedure was 4.0 years (0.5-12.0). The median blood loss was 2.0 mL (1.0-150.0 mL). The median operation time was 45.0 min (27.0-230.0), and the median hospital stay was 6.0 days (5.0-9.0). Three patients (6.1%) experienced severe surgical complications: 2 experienced a rupture of the right atrium and 1 had pericardial injury. Patients were followed up for 7-120 months after surgery. The postoperative results were excellent in 46 cases (93.9%) and good in 3 (6.1%). Twenty-four of the 49 patients have had their bars removed. The median time for bar removal was 36.0 months (24.0-47.0). The outcome after bar removal surgery was excellent in 20 cases and good in 4.ConclusionsPatients may develop PE or worsening of preexisting PE after open heart surgery for CHD. Surgery for PE can still be performed by the standard Nuss technique without increasing the risk of cardiac injury for the patients that have had interventional cardiology procedures for CHD previously. However, the risk of cardiac injury during the Nuss procedure dramatically increases due to retrosternal adhesions that develop after open heart surgery for CHD. In our experience, the Nuss procedure is safe and feasible after open heart surgery for CHD when performed by an experienced pectus surgeon using an individualized surgical plan for each patient.Type Of StudyRetrospective study.Level Of EvidenceLevel IV.Copyright © 2018 Elsevier Inc.
