Objective To report the result of surgical treatment for 144 children with ventricular septal defect and severe pulmonary hypertension. Method The diagnosis had been confirmed by cardiac catheter before the operation, Pp/Ps (0. 81±0.09) and Rp (9.41 ±5.37 ) wood. Ventricular septal prothesis was performed under cardiopulmonary bypass. Transthoracic intracardiac monitoring line inserted into pulmonary artery in 117 cases. Results Fourteen cases died of the 144 postoperatively, with mortality of 9.12% . Preoperative Pp/Ps≥0. 8 and Rp≥10 wood made the mortality higher than that of others ( P < 0. 05 ) . 32 persons had post - operative SpPA > 50 mmHg among the survivors and among the children with preoperative Pp/Ps ≥0. 8 and Rp≥10 wood the mortality was 28. 6 % being higher than that among those with Pp/Ps≥0. 8 and Rp < 10 wood. Conclusion The higher the preoperative Pp/Ps and Rp are, the higher the surgical mortality is. The prevention and treatment of postoperative pulmonary hypertension crisis should be given more attention. The placement of transthoracic intracardiac monitoring lines plays an important role in the prevention and treatment of the complications occurring postoperationally in children with pulmonary hypertension.
