Abstract

Objective: Evaluating the effectiveness and safety of minimally invasive surgery through the right vertical infra-axillary mini-thoracotomy for patients with ventricular septal defects weighing less than 5 kg at the Heart Center – Vietnam National Children's Hospital. Methods: From February 2021 to January 2022, 28 patients diagnosed with ventricular septal defects weighing less than 5kg underwent minimally invasive surgery for closure of the ventricular septal defect at the Heart Center – Vietnam National Children's Hospital using the right vertical infra-axillary mini-thoracotomy approach was retrospectively performed. Results: There were 28 patients collected in this study, with 8 male and 20 female patients. The median weight and median age of patients in this group were 4.8 kg (IQR, 4.5-5 kg) and 4.1 months (IQR, 3.52-4.78 months). The mean diameter of the ventricular septal defect was 8.3 ± 1.4 mm. Three patients (10.7%) are associated with patent ductus arteriosus, and 2 patients have left superior vein cava. The location of ventricular septal defect was: 22 patients (78.6%) were perimembranous, 3 patients (10.7%) were sub-aortic, 2 patients were doubly-committed, and 1 patient was inlet. The mean time of operation was 157.2 ± 22.2 minutes, mean aortic cross-clamp time was 45.04 ± 13.4 minutes, and mean bypass time was 68.4 ± 13.9 minutes. The median length of incision was 5 cm (IQR, 4-5 cm). The mean time of ventilation was 11.7± 19.8 hours. There was no mortality or need to convert to the other approach. Three patients (10.7%) developed arrhythmia after operation (2 had junctional ectopic tachycardia, and 1 had sinus bradycardia), and 2 patients (7.1%) had a small residual ventricular defect. The last follow-up showed no residual ventricular septal defect and no chest deformity in all patients. Conclusions: The primary outcomes of minimally invasive surgery through the right vertical infra-axillary mini-thoracotomy for patients with ventricular septal defects weighing less than 5 kg at Vietnam National Children’s Hospital were safe and effective. Studies with larger patient populations and longer follow-up periods are needed to accurately assess the effectiveness of this treatment.
