The descending thoracic aorta is the most common site for thoracic aneurysms to occur and may present asymptomatically or manifest itself with an array of symptoms depending on the involvement of adjacent structures. Hemoptysis may occur due to erosion of the aneurysm into a bronchus or the pulmonary parenchyma. This report describes the technique in a patient with a descending thoracic aneurysm who underwent emergent resection of the aneurysm with en bloc removal of the involved left lower lobe of the lung.
