case_images: Computed tomographic angiography, coronary section. Occlusion of the left subclavian artery starting from its origin at the aorta, with weak collaterals filling the distal portion and left subclavian artery occluded from its division from the aorta, filled by weak collaterals in the distal part and the left carotid artery showing pre-occlusive narrowing up to the middle just after its origin.

case_images: Additionally, the left common carotid artery showed short segment (approximately 1.5 cm) of pre-occlusive narrowing up to the middle just after its origin (Figure 1).
case_images: An 8-mm dacron graft was threaded through the mediastinum and anastomosed distally to the left common carotid artery. Subsequently, another 8-mm dacron graft was anastomosed to the distal portion of the subclavian artery and the proximal end of the graft was anastomosed to the ascending aorta.

case_images: The distal of the graft was then anastomosed to the distal portion of the subclavian artery, while the proximal end of the graft was anastomosed to the ascending aorta (Figure 2).
case_images: Coronal contract-enhanced thorax CT angiography images showed the patency of the graft and the proximal and distal anastomoses.

case_images: Furthermore, the grafts remained patent, and the anastomoses showed no signs of obstruction in the follow-up CT angiography (Figures 3-5).
