A 29-year-old male patient with acute ischemic stroke receiving bridging therapy, NIHSS 10. A Preoperative MRI showed an acute infarction in the left cerebral hemisphere. B, C, and D DSA showed left M1 occlusion with good collaterals, and this patient was treated with endovascular thrombectomy. E Repeat angiography showed an intracranial atherosclerotic severe stenosis in the lesion. F and G This patient received a rescue therapy including balloon angioplasty (Gateway 2.5 × 15 mm) with stenting (Neuroform 3.5 × 15 mm), and the outcome was mTICI 3. H A 6-month follow-up angiogram showed good stent apposition to the parent artery wall, and the degree of stenosis was worse compared with the initial outcomes after procedure
