The surgical treatment of obstructed total anomalous pulmonary venous connection / 中华胸心血管外科杂志

ABSTRACT

Objective:To analyze the results of surgical treatment in patients with obstructed total anomalous pulmonary venous connection.Methods:Inclusion criteria Patients with obstructed total anomalous pulmonary venous connection, who underwent surgical treatment in our hospital between December 2012 to January 2018. Exclusion criteria (1)With complicated malformations, such as single ventricle and visceral inversion; (2)The maximum flow velocity of pulmonary vein was less than 1.2 m/s; (3)Had not underwent surgery. 57 patients[33 males and 24 females, age (3.2±1.7) months, weight (5.0±0.9) kg] were enrolled. There were four anatomical subtypes supracardiac type(n=30), cardiac type(n=16), infracardiac type(n=5), and mixed type(n=6). Patients were followed up after operation.Results:During the follow-up of(52±21) months, 8 cases(14.0%, 8/57) died postoperatively. Postoperative pulmonary vein stenosis was present in 7 patients(12.3%, 7/57). The mortality of patients with postoperative pulmonary vein stenosis(57.1%, 4/7) was significantly higher than that of patients without postoperative pulmonary vein stenosis(8.0%, 4/50).Conclusion:The results of surgical treatment in patients with obstructed total anomalous pulmonary venous connection were encouraging, however, recurrent pulmonary venous stenosis still should be taken care.
