Transaxillary Approach for Surgical Repair of Simple Congenital Cardiac Lesions: Pitfalls, and Complications.

BACKGROUND

In the treatment of simple congenital cardiac lesions, percutaneous and cosmetic surgical approaches have steadily gained prominence. Surgically, right vertical axillary approach is sparsely used despite superior cosmesis and less pain and blood product usage. Knowledge of potential pitfalls could lead to its more widespread acceptance.

METHODS

We retrospectively analyzed perioperative outcomes of 104 consecutive patients who underwent surgery by this technique between mid-2016 and December 2019, including ostium secundum (67), sinus venosus (34), coronary sinus (1), and ostium primum (1) atrial septal defects and hemianomalous pulmonary venous connection (1). Perioperative variables, surgical times, complications, and follow-up data were analyzed.

RESULTS

Patient weight ranged from 6.8 to 41 kg. Incision length ranged from 4 to 6 cm. There was no mortality. All cannulation was central. Difficulty in cannulation (inferior vena cava) was seen in two patients. Morbidity included pneumothorax in 2 (1.9%) patients and subcutaneous emphysema necessitating prolonged intercostal drain retention in 20 (19.2%) patients. Surgical time increased linearly (r = 0.567; < .001) with increasing patient weight but cardiopulmonary bypass (CPB) time remained unaffected. No chest deformities or paresthesia were noted on follow-up. Scar size decreased in some patients.

CONCLUSIONS

Right vertical axillary approach can be safely employed to treat simple congenital cardiac lesions with adequate awareness of potential pitfalls. Increasing patient weight increases the surgical time but does not affect CPB times. Incidence of pneumothorax and subcutaneous emphysema is similar to other thoracotomy approaches. It is cosmetically superior.
