Tuberculous aneurysm of the descending thoracic aorta

Tuberculous aneurysm of the descending thoracic aorta is a rare entity. To our knowledge the present case is the sixth on record to have been successfully treated surgically. These aneurysms present the usual difficulties of surgical therapy of the thoracic aorta: spinal cord and renal circulatory protection and the choice between distant or in situ revascularization. This case is of particular interest for its evolution and its treatment: resection of the aneurysm without shunting and insertion of a graft in situ covered by a flap of omentum.
