Endovascular treatment of a symptomatic aneurysm of the left subclavian artery.

Upper extremity ischemia is a rare entity usually due to emboli of arterial origin. Such thromboemboli produce acute symptoms of sufficient severity as to necessitate early surgical intervention. We report the case of a patient with severe ischemia in his left hand, in whom the embolic source was a mural thrombus localized at the level of a saccular aneurysm of the subclavian artery. After having excluded the presence of a thoracic outlet syndrome, the lesion was successfully treated by means of percutaneous implantation of a stent graft with the exclusion of the aneurysm and the sealing of the thrombus.
