LUNG-CANCER FOUND IN A PATIENT WITH ABSENCE OF THE INFERIOR VENA-CAVAASSOCIATED WITH A LEFT SUPERIOR VENA-CAVA

A patients with anomalies of the main systemic veins developed lung ca ncer. In this patient, the large hemiazygos vein emptied into the left superior vena cava which communicated with the right atrium through t he coronary sinus. The cancer was located in the right upper lobe and directly invaded the mediastinum. Fortunately, because of the absence of a right superior vena cava in the normal position, the tumor was co mpletely resected by sleeve upper lobectomy without necessitating angi oplastic procedures.
