RESUMO
When the proximal occlusion or stenosis of the subclavian or of the brachiocephalic artery may require distal arterial filling through reversal flow from the vertebral artery, causing clinically significant blood supply reduction to the brainstem, it is called subclavian steal syndrome (SSS). We report a 54-year-old male patient who presented with multiple episodes of syncopes and vascular claudication due to right SSS. He underwent an angioplasty, evolving with complete improvement of the symptoms. We review the clinical presentation, the diagnosticmethods, and the treatment options of the disease.

Background Fibromuscular dysplasia (FMD) affects predominantly the cervical and renal arteries and may cause the classical angiographic pattern of string-of-beads. The diagnosis is increasing with the advances of imaging techniques. Case Report A 37-year-old man presenting with subarachnoid hemorrhage due to a dissecting aneurysm of the vertebral artery was treated by angioplasty with stent, with good outcome. All of the cervical and renal arteries were diseased and showed dysplasia and/or ectasias. Conclusions There are no guidelines or protocols to treat patients with FMD.
