title: Lobectomy for a mediastinal basal pulmonary artery.
abstract: Anatomical variations of the pulmonary artery increase the risks for vessel injury and critical mistakes during pulmonary artery resection. The mediastinal basal pulmonary artery is a rare branch abnormality and is the first branch of the pulmonary artery to flow into the basal segment. We report a patient who underwent video-assisted thoracic surgery (VATS) right lower lobectomy for lung cancer with a mediastinal basal pulmonary artery. The mediastinal basal pulmonary artery was detected preoperatively by computed tomography. During VATS, this artery was found with careful dissection by dividing the lung parenchyma within the fissure, and right lower lobectomy was safely performed.
