RESUMO
Subclavian steal syndrome is a group of symptoms resulting fromretrograde flow in the vertebral artery, "stealing" blood from the posterior intracranial circulation and other territories, caused by stenosis or occlusion of the subclavian artery proximal to the origin of the same vertebral artery, or even of the brachiocephalic trunk. Most of the time, it is an incidental finding in patients with other conditions or cerebrovascular risk factors. We report a series of 29 patients with an angiographic diagnosis, in which 7 received treatment (all endovascular), all with symptoms directly related to this condition. Advanced age, systemic arterial hypertension, diabetes mellitus, smoking and stroke were comorbidities frequently related. Six patients improved completely after the procedure and one remained with vertigo.

Atheromatous obstructive lesions of the arch vessels that contain thrombi are at high risk for distal embolization during angioplasty. This can lead to catastrophic neurological complications. We report a case of acute-on-chronic ischemia of the left upper limb due to thrombus-containing subclavian artery stenosis. After placement of an intravascular filter device, angioplasty and stent implantation successfully relieved the stenosis without any complications.
