Comparison of the clinical effect between the lower sternal incision and the left parasternal fourth intercostal incision in the transthoracic closure of ventricular septal defect

Abstract

Background: To analyze the clinical effect of two different ways of minimally invasive transthoracic closure in children with ventricular septal defect (VSD). Methods: From January 2015 to July 2019, 294 children with VSD were enrolled in the Fujian Medical University Union Hospital. Patients were divided into two groups – those who underwent VSD closure through the left sternal fourth intercostal incision (group A: n = 95) and the lower sternal incision (group B: n = 129). Results: The operation time, bleeding volume, postoperative mechanical ventilation time, postoperative intensive care unit (ICU) monitoring time, postoperative hospitalization time and complication rate in group A were significantly lower than those in group B (P < 0.05). There was no significant difference between the two groups in the operation success rate, mechanical ventilation time and total hospitalization cost (P > 0.05). Conclusion: The transthoracic closure of ventricular septal defect through the left sternal fourth intercostal incision is feasible, safe, cosmetic, and worth popularizing.
