[Endovascular stent-graft insertion followed by resection of a locally-advanced lung tumor that invaded the thoracic aorta].

A 52-year-old man with fever and dyspnea was admitted to our hospital. Chest computed tomography showed a mass measuring 3.5×3.0 cm in the S(1+2) segment of the left lung with involvement of the aorta. Although cytological examination using broncho fiberscopy did not show any malignancy, we suspected the mass to be T4N0M0 lung cancer. The tumor was diagnosed as having invaded the aorta using intravascular ultrasound. First, an endovascular graft was inserted, and then, a left upper lobectomy with resection of the infiltrated aortic wall was performed without cardiopulmonary bypass. The patient had an uneventful recovery without any complications. Pathological examination revealed the tumor to be a large-cell carcinoma. We think that an aortic endograft can be useful for resection of an infiltrated aortic wall, although further studies are necessary.
