Long-term Results of the Single-Patch Repair Technique for Sinus Venosus Atrial Septal Defects

Background: Anomalous pulmonary venous drainage commonly accompanies sinus venosus atrial septal defects (SVASDs). Many techniques have been reported for avoiding postoperative complications, such as narrowing of the superior vena cava (SVC) or the pulmonary system, and arrhythmia. We perform a single V-Y pericardial patch plasty repair technique for SVASDs. The purpose of this study is to report on the long-term results of this surgical technique. Methods: We retrospectively analyzed patients who had a diagnosis of ASD and who underwent their operations between 2000 and 2010 at the Gulhane Military Medical Academy Haydarpasa Training Hospital. Thirty-nine of the patients had an anomalous pulmonary return, and the single pericardial patch technique had been performed in 32 of these patients. Results: The mean (+/- SD) postoperative extubation time was 5 +/- 1.6 hours. The mean drainage volume was 384 +/- 137 mL. All patients were discharged from the hospital at a mean of 4.6 +/- 1.1 days after their operation and were prescribed anticoagulants for 3 months. No perioperative or late-term mortality was observed. Patients were followed up for 6 months to 2 years. There were no residual shunts and no stenosis-related findings in the pulmonary venous system or the SVC. Conclusion: Use of the single pericardial patch plasty technique might lower complication rates in patients with SVASD, especially those who have not completed their growth.
