[A case of surgically treated tuberculous aneurysm of descending thoracic aorta with massive hemoptysis].

A tuberculous aneurysm of the thoracic descending aorta was found in a 60-year-old female with massive hemoptysis. She had had lung tuberculosis one and half years ago. Computed tomography and aortic angiography revealed saccular type aneurysm at left supradiaphragmatic portion of descending aorta. After antituberculous chemotherapy, the aneurysm was resected under the temporary bypass support utilizing Bio-pump and the aorta was grafted with Dacron prosthesis successfully. The microscopic findings of specimens over the aneurysm and surrounding tissues revealed tuberculosis. The patient is doing well one year after the operation.
