Abstract
A 28-year-old woman presented with 3-month history of fever of unknown origin and progressively increasing cough. She was diagnosed with pulmonary tuberculosis on bronchial lavage cultures. A chest X-ray performed on follow-up showed a new opacity in the left apical area of the chest. Computed tomography scan of chest showed a large 10 cm pseudoaneurysm of the left subclavian artery 1 cm from its take off from the arch of the aorta. The pseudoaneurysm was approached through a left posterolateral thoracotomy and opened following a proximal and distal control. A 3 cm longitudinal defect was identified in the subclavian artery within its intrathoracic portion. This was debrided and repaired with an autologous pericardial patch. The patient had an uneventful recovery and remained well on follow-up.
