乳児心室中隔欠損症における早期根治手術の必要性に関する検討

抄録

Studies on the necessity of early surgical closure of a large ventricular septal defect in infancy were carriedout comparing the two groups of infants requiring operation under 12 months of age and those at 12 to 24 months of age from the viewpoints of preoperative status and postoperative courses. In the infants under 12 months of age with symptoms, postoperative complications appeared more frequently as a reflection of the presence of preoperative complications. The hospital motality was 10.5%. Therefore, careful postoperative management is required in this group. However, the risk of operation is acceptable and surgical improvement is satisfactory. On the other hand, in the infants 12 to 24 months of age, postoperative complications appeared less frequently. There is on hospital death and all survivors are asymptomatic. Whereas the complications of surgery appear no gerater in infancy, we prefer to perform early surgical closure of a large ventricular septal defect in the infants with symptom.
