Head computed tomography (CT) revealed a subarachnoid hemorrhage around the right Sylvian fissure and large intracranial hematoma in the right parietal lobe. The CT angiography showed a saccular aneurysm in the peripheral cortical segment of the right angular branch of the right DMCA. We decided to perform a right craniotomy to evacuate hematoma and interrupt the aneurysm. Just after the dural incision, the aneurysm ruptured again. We applied a temporary clip on the artery proximal to the aneurysm before excising it.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>Aneurysm in DMCA can be treated safely with surgical excision and risk of sudden recurrent hemorrhage needs to be anticipated.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_479_2021","type":"journal-article","created":{"date-parts":[[2021,8,16]],"date-time":"2021-08-16T14:10:53Z","timestamp":1629123053000},"page":"412","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Massive intracerebral hemorrhages due to peripheral middle cerebral artery aneurysm rupture: A case report with a surgical video"],"prefix":"10.25259","volume":"12","author":[{"given":"Takuma","family":"Aoki","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yukihiro","family":"Goto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yujiro","family":"Komaru","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shigeomi","family":"Yokoya","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hideki","family":"Oka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10894","published-online":{"date-parts":[[2021,8,16]]},"reference":[{"key":"10.25259\/SNI_479_2021\/ref-1","doi-asserted-by":"crossref","first-page":"1287","DOI":"10.1007\/s00701-005-0622-3","article-title":"Aneurysm in the penetrating artery of the distal middle cerebral artery presenting as intracerebral haemorrhage","volume":"147","author":"Ahn","year":"2005","journal-title":"Acta Neurochir (Wien)"},{"key":"10.25259\/SNI_479_2021\/ref-2","doi-asserted-by":"crossref","first-page":"121","DOI":"10.1016\/j.neuchi.2013.04.007","article-title":"Distal middle cerebral artery aneurysm: A proposition of microsurgical management","volume":"59","author":"Calvacante","year":"2013","journal-title":"Neurochirurgie"},{"key":"10.25259\/SNI_479_2021\/ref-3","doi-asserted-by":"crossref","first-page":"553","DOI":"10.1016\/j.surneu.2007.03.023","article-title":"Microneurosurgical management of distal middle cerebral artery aneurysms","volume":"67","author":"Dashti","year":"2007","journal-title":"Surg Neurol"},{"key":"10.25259\/SNI_479_2021\/ref-4","doi-asserted-by":"crossref","first-page":"94","DOI":"10.1227\/01.neu.0000429842.61213.d5","article-title":"A new, more accurate classification of middle cerebral artery aneurysms: Computed tomography angiographic study of 1, 009 consecutive cases with 1, 309 middle cerebral artery aneurysms","volume":"73","author":"Elsharkawy","year":"2013","journal-title":"Neurosurgery"},{"key":"10.25259\/SNI_479_2021\/ref-5","doi-asserted-by":"crossref","first-page":"12","DOI":"10.1177\/1591019915617317","article-title":"Endovascular treatment of distal middle cerebral artery aneurysms: Report of eight cases and literature review","volume":"22","author":"Lv","year":"2016","journal-title":"Interv Neuroradiol"}],"container-title":["Surgical Neurology International"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/surgicalneurologyint.com\/massive-intracerebral-hemorrhages-due-to-peripheral-middle-cerebral-artery-aneurysm-rupture-a-case-report-with-a-surgical-video\/","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/surgicalneurologyint.com\/surgicalint-articles\/massive-intracerebral-hemorrhages-due-to-peripheral-middle-cerebral-artery-aneurysm-rupture-a-case-report-with-a-surgical-video\/","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,8,16]],"date-time":"2021-08-16T14:10:58Z","timestamp":1629123058000},"score":1,"resource":{"primary":{"URL":"http:\/\/surgicalneurologyint.com\/surgicalint-articles\/massive-intracerebral-hemorrhages-due-to-peripheral-middle-cerebral-artery-aneurysm-rupture-a-case-report-with-a-surgical-video\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,8,16]]},"references-count":5,"alternative-id":["10.25259\/SNI_479_2021"],"URL":"https:\/\/doi.org\/10.25259\/sni_479_2021","relation":{},"ISSN":["2152-7806"],"issn-type":[{"value":"2152-7806","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,8,16]]},"article-number":"412"}}
