Percutaneous endovascular angioplasty was performed in a male patient aged in their 80 s with subclavian artery steal syndrome and paroxysmal syncope. (A) The right subclavian artery stenosis was approximately 95% on agngioraphy. (B) After deployment of a balloon-expandable stent at the stenotic segment, the stenosis disappeared. (C) Embolism occurred in the right middle cerebral artery causing disappearance of the right middle cerebral artery. (D) After immediate endovascular mechanical thrombectomy, patency of the right middle cerebral artery was restored, resulting in the thrombolysis in cerebral infarction score of 2b.
