RESUMO
Takayasu's arteritis is a chronic inflammatory disease of unknown origin in which cell-mediated inflammation involves large arteries progressing from the adventitia to the intima, until the lumen of the vessel is narrowed. Here we report a case of a 48-year-old female patient who was diagnosed with Takayasu's arteritis 6 years ago. At that time, because of severe involvement of both the right and left carotid arteries, she underwent application of a Hemashield vascular prosthesis, including the ascending aorta, left common carotid artery, and right common carotid artery. Due to the fact that there were also bilateral subclavian artery stenoses, the application of the prosthesis induced bilateral subclavian steal syndrome. This year she developed stenosis of the prosthesis and the bilateral subclavian steal syndrome disappeared until she underwent percutaneous transluminal angioplasty, which restored cerebral flow through the carotid arteries after which the subclavian steal syndrome reappeared.
