Abstract: Objective: To summarize the surgical treatment for ventricular septal defect(VSD) combined with pulmonary hypertension(PH) in children.Methods: Fifteen patients with ventricular septal defect combined with pulmonary hypertension diagnosed by color Doppler flow imaging(CDFI) were included in this group and underwent the Dacron patch repair under hypothermal cardiopulmonary by pass.Results: Death occurred in no patients after the operation.The low cardiac output occurred in two patients and the hydrothorax in one patient.The residual shunt of 2 mm was found in the CDFI in one patient when discharged from the hospital.The clinical symptoms disappeared and the state of the nutrition and the development for the patients was significantly improved in the follow-up 12 months.Conclusions: Most children with ventricular septal defect combined with pulmonary hypertension can be cured with early diagnosis and treatment.The operation is safe.After the operation the patient can recover completely.
