Case 1 Presentation: A 45-year-old female patient with sudden onset of headache, followed by somnolency. CT scan showed a four-ventricle hematocephalus caused by a 27 \u00d7 31 \u00d7 17 mm hematoma located in the left basal ganglia. Angiography revealed a 3 mm aneurysm on hypertrophic lenticulostriate artery bridging the M1 occlusion. Selective catheterization and distal embolisation with acrylic glue was done. Case 2 Presentation: A 47-year-old woman was admitted for a sudden onset of severe headache, CT scan showed four-ventricle hematocephalus. A 4 mm aneurysm on the collateral vessel\u2013anterior chorioidal artery bridging the closure of the terminal segment of the internal carotid artery was diagnosed as the source of bleeding. Selective catheterization and distal embolisation with acrylic glue was done. Conclusions: Selective embolisation of ruptured aneurysms on moya moya collaterals is a simple, effective, and safe procedure when relevant microcatheters are used with imaging software navigation such as 3D DSA, 3D road map and flat-panel CT.<\/jats:p>","DOI":"10.3390\/medicina60091499","type":"journal-article","created":{"date-parts":[[2024,9,16]],"date-time":"2024-09-16T04:14:07Z","timestamp":1726460047000},"page":"1499","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Endovascular Therapy of Ruptured Aneurysms on Moyamoya Collateral Vessels: Two Cases"],"prefix":"10.3390","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7793-0375","authenticated-orcid":false,"given":"Pavel","family":"Ry\u0161ka","sequence":"first","affiliation":[{"name":"Department of Radiology, University Hospital, 50005 Hradec Kralove, Czech Republic"},{"name":"Faculty of Medicine in Hradec Kralove, Charles University, 50003 Hradec Kralove, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miroslav","family":"Loj\u00edk","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital, 50005 Hradec Kralove, Czech Republic"},{"name":"Faculty of Medicine in Hradec Kralove, Charles University, 50003 Hradec Kralove, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ji\u0159ina","family":"Habalov\u00e1","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Hospital, Faculty of Medicine, Charles University, 50005 Hradec Kralove, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carmen","family":"Kajzrov\u00e1","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Hospital, Faculty of Medicine, Charles University, 50005 Hradec Kralove, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tom\u00e1\u0161","family":"\u010ces\u00e1k","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Hospital, Faculty of Medicine, Charles University, 50005 Hradec Kralove, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eva","family":"V\u00edtkov\u00e1","sequence":"additional","affiliation":[{"name":"Department of Neurology, University Hospital, Faculty of Medicine, Charles University, 50005 Hradec Kralove, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Barto\u0161","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Hospital, Faculty of Medicine, Charles University, 50005 Hradec Kralove, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zden\u011bk","family":"B\u011blobr\u00e1dek","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital, 50005 Hradec Kralove, Czech Republic"},{"name":"Faculty of Medicine in Hradec Kralove, Charles University, 50003 Hradec Kralove, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anton\u00edn","family":"Krajina","sequence":"additional","affiliation":[{"name":"Department of Radiology, University Hospital, 50005 Hradec Kralove, Czech Republic"},{"name":"Faculty of Medicine in Hradec Kralove, Charles University, 50003 Hradec Kralove, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"288","DOI":"10.1001\/archneur.1969.00480090076012","article-title":"Cerebrovascular moyamoya disease: Disease showing abnormal net-like vessels in base of brain","volume":"20","author":"Suzuki","year":"1969","journal-title":"Arch.
