Endovascular aneurysm repair of saccular descending thoracic pseudoaneurysm possibly associated with tuberculosis

In 2010, an 84-year-old man underwent thoracic endovascular aneurysm repair (TEVAR) for the saccular descending thoracic pseudoaneurysm (DTAA), which was adherent to the pulmonary lobe and thoracic vertebrae. Past medical history comprised twice anti-tuberculous medications for pulmonary tuberculosis and tuberculous vertebral osteomyelitis. The dilated aorta was detected at the time of medication for tuberculous vertebral osteomyelitis 24 years ago. However, he was not indicated for the operation, and he was lost to follow-up until now. The association of tuberculosis bacilli was suspected through clinical course as an origin of DTAA, although the histopathological examination was not performed because of invasion. TEVAR was performed considering: (1) no preoperative ongoing inflammation, (2) no evidence of tuberculosis recurrence, and (3) risk factors, such as pulmonary impairments and high age. Several months have been passed since the operation, and the patient remains well without perioperative anti-tuberculous medications.
