肺動脈閉鎖合并室間隔缺損行肺動脈下拉重建右心室流出道近中期效果觀察
[Abstract]:Objective to observe the clinical effect of pulmonary artery atresia (PA) combined with ventricular septal defect (VSD) on pulmonary artery pull-down reconstruction of right ventricular outflow tract (RVOT). Methods 54 children with PA combined with VSD underwent pull-down reconstruction of RVOT. The mortality and complications were recorded in the middle and near postoperative period (1st and 6th month after operation). The development of pulmonary artery and its branches, the area of tricuspid valve and pulmonary artery regurgitation, and the change fraction of right ventricular area (RVFAC),) were observed by echocardiography. Ratio of tricuspid annular systolic displacement (TAPSE), tricuspid peak diastolic velocity (Em) to late diastolic peak velocity (Am) (Em/Am), right ventricular ejection fraction (RVEF).) Results there were 6 cases of death and 11 cases of complications in the first month after operation in 54 cases, and no further death occurred until the sixth month. The diameter and the area of tricuspid regurgitation of pulmonary artery anastomosis, left pulmonary artery opening, right pulmonary artery orifice and tricuspid regurgitation were increased 6 months after operation (all P 0.05). There was no significant difference in the right ventricular function between the first month and the first month after operation (P 0.05). Conclusion the pulmonary artery anastomosis and branch growth in children with PA combined with VSD after pulmonary pull-down reconstruction with RVOT are good, and the right heart function is good in the near and middle period after operation.
