title: Pulmonary artery reconstruction with a tailor-made bovine pericardial conduit following sleeve resection of a long segmental pulmonary artery for the treatment of lung cancer: technical details of the dog-ear method for adjusting diameter during vascular anastomosis.
abstract: Sleeve resection of the pulmonary artery (PA) is always required for lung-sparing operations in which half or more of the vessel circumference is infiltrated by the primary tumor or metastatic hilar nodes. Following sleeve resection, conduit reconstruction may be indicated if there is excessive distance between the two vascular stumps, because there is a high degree of tension when repaired by direct anastomosis. We herein present a case of PA reconstruction using a tailor-made bovine pericardial conduit after sleeve resection of PA during lung cancer surgery. The length of resection was longer than 3 cm, and the difference in diameter between the conduit and peripheral PA stump was larger than 0.5 cm. We describe the surgical and oncological merits of a bovine pericardial conduit, and provide details of our reconstruction technique, focusing on adjustment of diameter between the conduit and peripheral PA (dog-ear method).
