The surgical procedures for living-donor lobectomy are sometimes influenced by the anatomical variations of the pulmonary vein (PV). The goal of this study was to analyse the PV variations in living donors and to review the influence of these variations on the surgical procedures used. METHODS: Between June 2008 and September 2018, 154 living donors underwent right or left lower lobectomy. The PV variations were analysed using 3-dimensional computed tomography (3D-CT), and the surgical management of these variations was reviewed. RESULTS: Among 154 donors, 21 PV variations that could influence the surgical procedure for a right lower lobectomy were found in 19 (12.3%) donors, whereas no such variations for a left lower lobectomy were found. Detected PV variations were dorsal branch of the right upper PV (n = 12), middle PV draining into the right lower PV (n = 6) and the superior segment branch of the right lower PV draining into the right upper PV (n = 3). Among 96 donors undergoing right lower lobectomy, 9 (9.4%) donors had PV variations that could influence the Presented at the 27th European Conference on General Thoracic Surgery, Dublin, Ireland, 9–12 June 2019.
