Giant intrathoracic aneurysm of the right subclavian artery with tracheal compression following neck gland biopsy for tubercular lymphadenitis: Treated by partial cardiopulmonary bypass and grafting — A case report

Intrathoracic aneurysm of the subclavian artery is very rare. This nine year old girl developed a giant intrathoracic aneurysm of the right subclavian artery with hoarseness, tracheal compression and absent radial pulse, following a tubercular neck node biopsy. Chest radiograph showed a superior mediastinal mass with rightward bulge. Computed Tomography (CT) scan of chest and vascular Doppler confirmed the diagnosis. The patient underwent inclusion grafting of the right subclavian artery aneurysm under partial Cardiopulmonary Bypass (CPB) and hypothermia via a median sternotomy with right supraclavicular extension. Post operative histopathology failed to specify the cause of the aneurysm. The patient made a complete recovery with a good radial pulse and radiological evidence of involution of the aneurysm cavity.
