ABSTRACT
Repair of pulmonary artery sling can be done through a left thoracotomy66 or median sternotomy with cardiopulmonary bypass.
This is the main method used.25,67 A left posterolateral thoracotomy is done through the fourth intercostal space. The superior part of the pulmonary hilum is dissected to identify the left pulmonary artery. The left pulmonary artery is dissected as far as possible and freed from the adjacent structures while the ligamentum arteriosum is divided. The patient is given a heparin dose of 1.5 mg/kg. The pulmonary artery is divided between clamps and the proximal stump closed with a continuous 5-0 polypropylene stitch.
