We herein report a case of an unruptured dissecting aneurysm of the MCA treated by stent-assisted coil embolization.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Case Description: <\/jats:title>\n<jats:p>A 65-year-old man with no history of trauma presented with a headache. Time-of-flight imaging revealed a dissecting cerebral aneurysm in the right M1 segment of the MCA, and the aneurysm had increased in size within a short time. We treated the aneurysm by endovascular stenting with coils, and the patient developed no neurological deficits.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>Because of the potential involvement of the lenticulostriate artery (LSA) in the area of dissection, choosing the best treatment (such as direct surgery or endovascular treatment) may be challenging. Treatment efficacy depends on whether the LSA is affected and on the length of the dissection. In our case, the dissection did not involve the LSA and could therefore be treated by stent-assisted coil embolization.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_619_2023","type":"journal-article","created":{"date-parts":[[2023,10,20]],"date-time":"2023-10-20T06:04:34Z","timestamp":1697781874000},"page":"375","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Stent assisted coil embolization for a dissecting cerebral aneurysm of middle cerebral artery: A case report and the literature review"],"prefix":"10.25259","volume":"14","author":[{"given":"Ayaka","family":"Shibano","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Kita-Harima Medical Center, Ono, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junichi","family":"Sakata","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kita-Harima Medical Center, Ono, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Atsushi","family":"Fujita","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kobe University Graduate School of Medicine, Kobe, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomoaki","family":"Harada","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kita-Harima Medical Center, Ono, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Reiichi","family":"Okino","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kita-Harima Medical Center, Ono, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daisuke","family":"Yamamoto","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kita-Harima Medical Center, Ono, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shigeru","family":"Miyake","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kita-Harima Medical Center, Ono, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2023,10,20]]},"reference":[{"key":"10.25259\/SNI_619_2023\/ref-1","first-page":"743","article-title":"Diagnosis and treatment of nontraumatic dissecting aneurysm in the middle cerebral artery","volume":"27","author":"Abiko","year":"1999","journal-title":"No Shinkei Geka"},{"key":"10.25259\/SNI_619_2023\/ref-2","doi-asserted-by":"crossref","first-page":"2289","DOI":"10.3174\/ajnr.A5388","article-title":"Treatment of middle cerebral artery aneurysms with flow-diverter stents: A systemic review and meta-analysis","volume":"38","author":"Cagnazzo","year":"2017","journal-title":"AJNR Am J Neuroradiol"},{"key":"10.25259\/SNI_619_2023\/ref-3","doi-asserted-by":"crossref","first-page":"228","DOI":"10.3171\/jns.2003.99.2.0228","article-title":"Spontaneous fusiform middle cerebral artery aneurysms: Characteristics and a proposed mechanism of formation","volume":"99","author":"Day","year":"2003","journal-title":"J Neurosurg"},{"key":"10.25259\/SNI_619_2023\/ref-4","first-page":"955","article-title":"A case of middle cerebral artery occlusion caused by dissecting aneurysm","volume":"24","author":"Fu","year":"1996","journal-title":"No Shinkei Geka"},{"key":"10.25259\/SNI_619_2023\/ref-5","doi-asserted-by":"crossref","first-page":"50","DOI":"10.2335\/scs1987.18.1_50","article-title":"Diagnosis for the intracranial dissecting aneurysms","volume":"18","author":"Kamiyama","year":"1990","journal-title":"Surg Cereb Stroke"},{"key":"10.25259\/SNI_619_2023\/ref-6","doi-asserted-by":"crossref","first-page":"296","DOI":"10.3171\/jns.1987.67.2.0296","article-title":"Dissecting aneurysms of the anterior circle of willis arteries.
