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.
