Feasibility study of interventional treatment for membranous ventricular septal defect in infants less than three years of age / 介入放射学杂志

ABSTRACT

Objective To study the feasibility and safety of interventional closure for the treatment of infant’s perimembranous ventricle septal defect (PmVSD). Methods During the period from Jan. 2012 to Jan. 2013, a total of 229 single PmVSD infants less than three years of age were admitted to authors ’ hospital. The infantile patients were divided into intervention group (n = 88) and surgery group (n = 141). Patients in the intervention group underwent interventional closure procedure , while patients in the surgery group received conventional cardiac surgery. The operation success rate , the main and minor complication rates, the operation time, the postoperative hospitalization days, the incidence of postoperative pulmonary infection and the medical cost were recorded , and the results were compared between the two groups. Results No statistically significant differences in the operation success rate, the main complication rate, the postoperative hospitalization days and the medical cost existed between the two groups (P > 0.05). But the minor complication rate and the operation time of the intervention group were better than those of the surgery group. In the surgery group, the minor complication was mainly the respiratory infection, which was manifested as higher leukocyte count, higher C-reactive protein level, higher myocardial damage marker level as well as higher vasoactive drug scores in 24 hours after the operation , and the above items were significantly higher than those in the intervention group. Conclusion For the treatment of infant’s perimembranous ventricle septal defect, percutaneous transcatheter closure is clinically feasible. This technique is safe and reliable with obvious advantages when the indication is strictly observed and the procedure is carefully manipulated. This treatment can partly replace the conventional surgery.
