a Three-dimensional reconstruction computed tomography image (posterior view) shows an aberrant artery branching out from the brachiocephalic trunk and the vein draining into the right pulmonary artery. b Intraoperative findings show the drainage vein (ligated; arrow) to the right pulmonary artery behind the dorsal pericardium (cut away) between the ascending aorta (pulled to the left side) and the superior vena cava(SVC). The right and left innominate veins and the SVC are taped. ELS extralobar sequestration, rmPA right main pulmonary artery, SVC superior vena cava
