Surgery for pulmonary venous stenosis after total anomalous pulmonary venous connection repair: Midterm results of 9 patients / 中国胸心血管外科临床杂志

ABSTRACT

@#Objective    To review our experience of reoperations for pulmonary venous stenosis (PVS) after total anomalous pulmonary venous connection (TAPVC) repair for the past decade in Fuwai Hospital. Methods    Nine patients underwent reoperation for PVS between 2009 and 2019 in Fuwai Hospital, including 4 males and 5 females with an average age of 5.10±5.00 years. The patients were divided into a sutureless group (n=3) and a non-sutureless group (n=6). Clinical data were reviewed and analyzed. Results    For primary TAPVC type, 4 patients were supracardiac, 2 patients were cardiac, 1 patient was infracardiac, and 2 patients were mixed-type anomaly. The median cardiopulmonary bypass time was 95 (63, 208) min, aortic clamping time was 58 (30, 110) min, ICU stay was 24 (24, 2 136) h. Early hospital death occured in 1 (11.1%) patient. One (11.1%) patient with single ventricle physiology had hospital comorbidity, who underwent hemofitration therapy. The follow-up time was 11.9 (2.2, 18.0) months, during which 1 patient died of restenosis of pulmonary vein and another patient died of stroke. No statistically significant difference was found between the sutureless group and non-sutureless group in postoperative or follow-up results (P>0.05). Conclusion    Surgery is effective for treatment of PVS after repair of TAPVC, yet with a realatively high morbidity and mortality. The advantage of sutureless repair over conventional repair for this particular group of patients is yet to be verified.
