Abstract
Video-assisted endoscopic techniques have recently been employed in congenital heart surgery for patent ductus arteriosus (PDA) interruption. We report our preliminary experience of using a new technique of single-lung ventilation to perform video-assisted thoracoscopic PDA interruption (VATS-PDA) in small infants and children. Sixteen infants with a mean body weight of 6.5 +/- 2.4 kg (range 2.6-12.8 kg) underwent VATS-PDA under selective right-lung ventilation using a 2-F balloon catheter for arterial embolectomy. We did not need to reposition the retractor or reinflate the atelectatic lung, as there was no transient hypoxia or hypercarbia. The mean procedure time was 81 +/- 27 min (range 45-145 min) and all patients, with the exception of one with a total anomalous pulmonary venous connection, were extubated in the operating room. This technique using single-lung ventilation for infants and small children was safe and effective in providing pediatric thoracic access and exposure within confined and delicate anatomic spaces.
