Surgical repair via submammary thoracotomy, right axillary thoracotomy and median sternotomy for ventricular septal defects.

BACKGROUND

Right submammary thoracotomy and right vertical infra-axillary thoracotomy are performed for ventricular septal defect (VSD) to reduce the invasiveness of the conventional surgical repair through median sternotomy approach. No comparative studies have been conducted among these three procedures.

METHODS

From January 2016 to December 2016, 182 patients with isolated VSD who underwent surgical repair via one of these 3 approaches were reviewed to compare these three procedures.

RESULTS

The procedure success rates were similar in these three groups. There was no statistically significant difference in operative time, aortic cross-clamping time, the duration of CPB, blood transfusion amount and medical cost. However, postoperative mechanical ventilation time, the duration of intensive care and postoperative length of hospital stay were longer in median sternotomy group than the other two groups. (P < 0.05) The median sternotomy group required the longest incision. No significant difference was noted in major adverse events. There were different advantages and disadvantages in the three kinds of operative procedures.

CONCLUSIONS

Regarding conventional surgical repair VSD, right submammary thoracotomy and right vertical infra-axillary thoracotomy both delivered better cosmetic results for patients with isolated VSD, while all the three procedures could obtain satisfactory clinical effect.
