  		Figure 1. (a) Axial CT image shows an aneurysm in the left thoracic outlet (arrow) and extravasation (arrowhead). (b) Reformatted coronal CT image reveals a 4.9 cmx3.7 cm aneurysm with mural thrombus (arrow) and massive intrathoracic haemorrhage (arrowhead).

  		Figure 2. (a) Aortogram shows an aneurysm (arrow) in the left thoracic outlet and the right vertebral artery is present within normal size (arrowhead). (b) Left subclavian arteriogram reveals that the aneurysm (arrow) is located close to the ostium of the left vertebral artery. (c) The microcatheter is inside the aneurysm of the left vertebral artery.

  		Figure 3. (a) Left vertebral arteriogram during coil embolisation shows that coils migrated into the huge aneurysmal sac (arrow). The distal portion of the left vertebral artery was occluded with microcoils (arrowhead). (b) Left subclavian arteriogram, after packing the aneurysm with coils, shows incomplete embolisation and extravasation (arrow). (c). Left subclavian arteriogram, post-liquid embolisation, shows that there was no aneurysm and no extravasation into the left thoracic cavity.
