Initial magnetic resonance imaging and magnetic resonance angiography revealed a small acute ischemic lesion in left parietal lobe with occlusion at the left middle cerebral artery. We performed an endovascular thrombectomy, which failed. Her neurological deficits remained unchanged. On the basis of immediate postendovascular magnetic resonance perfusion, diffusion-weighted imaging (DWI), and neurological examination, an obvious clinical-DWI and a DWI\u2013perfusion-weighted imaging mismatch were detected. We decided to perform emergency superficial temporal artery to middle cerebral artery bypass to prevent further progression of cerebral ischemia. On a 3-month follow-up, neurological deficits remained minimal motor aphasia and dysarthria.<\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n Following failed endovascular treatment in patients with acute symptoms attributed to major cerebral artery occlusion, we recommend immediate multimodal neuroimaging. If there are clinical-DWI and DWI\u2013perfusion-weighted imaging mismatch indications, surgical revascularization could be considered as the next salvageable strategy.<\/jats:p>\n <\/jats:sec>","DOI":"10.1097\/nrl.0000000000000086","type":"journal-article","created":{"date-parts":[[2016,12,24]],"date-time":"2016-12-24T20:36:15Z","timestamp":1482611775000},"page":"14-17","source":"Crossref","is-referenced-by-count":11,"title":["Urgent Bypass Surgery Following Failed Endovascular Treatment in Acute Symptomatic Stroke Patient With MCA Occlusion"],"prefix":"10.1097","volume":"22","author":[{"given":"Chang Yeob","family":"Lee","sequence":"first","affiliation":[{"name":"Neurology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chang Hyun","family":"Kim","sequence":"additional","affiliation":[{"name":"Neurosurgery, Keimyung University Dongsan Medical Center, Daegu, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chang-Young","family":"Lee","sequence":"additional","affiliation":[{"name":"Neurosurgery, Keimyung University Dongsan Medical Center, Daegu, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung-Il","family":"Sohn","sequence":"additional","affiliation":[{"name":"Neurology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeong-Ho","family":"Hong","sequence":"additional","affiliation":[{"name":"Neurology"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-20230929","doi-asserted-by":"crossref","first-page":"3024","DOI":"10.1161\/STR.0000000000000074","article-title":"2015 AHA\/ASA focused update of the 2013 guidelines for the early management of patients with acute ischemic stroke regarding endovascular treatment: a guideline for healthcare professionals from the american heart association\/american stroke association","volume":"46","author":"Powers","year":"2015","journal-title":"Stroke"},{"key":"R2-20230929","doi-asserted-by":"crossref","first-page":"38","DOI":"10.5853\/jos.2015.17.1.38","article-title":"Case characteristics, hyperacute treatment, and outcome information from the clinical research center for stroke-fifth division registry in South Korea","volume":"17","author":"Kim","year":"2015","journal-title":"J Stroke"},{"key":"R3-20230929","doi-asserted-by":"crossref","first-page":"217","DOI":"10.1007\/s11940-010-0110-9","article-title":"Managing malignant cerebral infarction","volume":"13","author":"Simard","year":"2011","journal-title":"Curr Treat Options Neurol"},{"key":"R4-20230929","doi-asserted-by":"crossref","first-page":"1191","DOI":"10.1056\/NEJM198511073131904","article-title":"Failure of extracranial-intracranial arterial bypass to reduce the risk of ischemic stroke.
