Left internal thoracic artery (LITA) pseudoaneurysm after coronary artery bypass graft is a rare complication. We report a case of LITA pseudoaneurysm after minimally invasive direct coronary artery bypass (MIDCAB) in a 79-year-old man who developed severe respiratory distress caused by haemoptysis.
The patient had a medical history of pneumoconiosis. One year earlier, he had a MIDCAB through a left mini-anterolateral thoracotomy for left anterior descending coronary artery stenosis. An emergency thoracic computed tomography scan showed an intrathoracic pseudoaneurysm of the LITA, 4.3 cm in maximal diameter, compressing the adjacent lung parenchyma ( Fig. 1 B, C). An emergency left subclavian arteriogram showed a fusiform pseudoaneurysm of the LITA, connecting with the bronchial artery via multiple collateral vessels ( Fig. 1 D).
