However, the standard management of acute intracranial embolism for this etiology has not been established, and there have been very few reports in the past.<\/jats:p><\/jats:sec><jats:sec id=\"st2\"><jats:title>Case Description:<\/jats:title><jats:p>A 68-year-old male was incidentally found to have an unruptured aneurysm of anterior communicating artery (ACoA). Immediately after the cerebral angiography for the purpose of detailed examination of the aneurysm, the right partial hemiparalysis and mild aphasia developed. Magnetic resonance imaging\/angiography (MRI\/A) revealed an occlusion in the peripheral part of the left middle cerebral artery (MCA). Due to the existence of magnetic resonance angiography-diffusion mismatch, emergent craniotomy was immediately performed to remove intra-arterial thrombus. We also performed clipping for an unruptured ACoA aneurysm with this approach. Postoperative MRI\/A showed that the occluded artery was recanalized and a slight infarction was observed in the left cerebral hemisphere. The patient was discharged on foot and followed at outpatient clinic over 4 years without no neurological deficit.<\/jats:p><\/jats:sec><jats:sec id=\"st3\"><jats:title>Conclusion:<\/jats:title><jats:p>Emergent surgical embolectomy for distal MCA occlusion related to cerebral angiography followed by neck clipping for an unruptured aneurysm of the ACoA was successful in treating acute occlusion of the peripheral part of the MCA in a patient with an unruptured aneurysm. As there are few similar cases, there is controversy about the best management, but this surgical method can be a safe and effective treatment.<\/jats:p><\/jats:sec>","DOI":"10.25259\/sni_627_2020","type":"journal-article","created":{"date-parts":[[2020,12,4]],"date-time":"2020-12-04T09:31:36Z","timestamp":1607074296000},"page":"420","update-policy":"http:\/\/dx.doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Emergent
