In living-donor lobar lung transplantation (LDLLT), donor surgeries are conducted in ways that ensure proper dissections for both donors and recipients. We report a case of LDLLT, in which pulmonary arterioplasties with autopericardial patch were performed on both a donor and a recipient. Since excision of the lingular branch of the pulmonary artery was carried out far lower than that of the upper segment of the left lower lobe branch, pulmonary arterioplasty was performed to avoid potential stricture of the remaining lingular branch. Also, because of the oblique stump of the graft pulmonary artery, pulmonary arterioplasty with autopericardial patch was required in the recipient.
