Abstract

We report the case of a very rare right mediastinal basal pulmonary artery (A7). A 61-year-old man was diagnosed with primary lung cancer in the right lower lobe (adenocarcinoma, cT2bN0M0 Stage IIA). Preoperative 3D-CT revealed a right aberrant A7 branching off directly from the right main pulmonary artery and passing down over the posterior surface of the pericardium, medially apart from the bronchus intermedius, into the right lower lobe. The patient underwent video-assisted right lower lobectomy with systematic lymphadenectomy. We identified and divided the aberrant pulmonary artery safely; that is, our knowledge of its existence in advance by 3D-CT probably prevented accidental bleeding during the surgery.
