The complex anatomical environment of the VBJ, and the complicated geometry of the fenestration make clipping of these aneurysms difficult. Therefore, endovascular treatment of these aneurysms is now widely accepted.<\/jats:p>\n<jats:p>The authors describe the case of a 43-year-old woman with sickle cell anemia. She presented with subarachnoid hemorrhage. Digital subtraction angiography was performed and depicted multiple intracranial aneurysms. The patient had a left superior hypophysial artery aneurysm, a right superior cerebellar artery\u2013posterior cerebral artery aneurysm, and a VBJ aneurysm associated with a fenestration of the BA. The VBJ aneurysm was not identified on the initial angiogram and was only revealed after 3D rotational angiography was performed. The 3D reconstruction was critical to the understanding of the complex geometry associated with the fenestrated BA. The VBJ was reconstructed using a combination endovascular technique. The dominant limb of the fenestration was stented and balloon-assisted coiling was performed, followed by sacrifice of the nondominant vertebral artery using coils and the embolic agent Onyx. Postoperative angiography demonstrated successful occlusion of the aneurysm with reconstruction of the VBJ.<\/jats:p>\n<jats:p>To the authors' knowledge, this is the first report of a fenestrated VBJ aneurysm treated with the combination of stenting, balloon remodeling, coiling, and vessel sacrifice. Three-dimensional angiography was critical in making the correct diagnosis of the source of the subarachnoid hemorrhage and with operative planning.<\/jats:p>","DOI":"10.3171\/2008.9.jns08170","type":"journal-article","created":{"date-parts":[[2008,11,14]],"date-time":"2008-11-14T15:18:18Z","timestamp":1226675898000},"page":"525-529","source":"Crossref","is-referenced-by-count":45,"title":["Fenestrated vertebrobasilar junction aneurysm: diagnostic and therapeutic considerations"],"prefix":"10.3171","volume":"110","author":[{"given":"Erminia","family":"Albanese","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonino","family":"Russo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arthur J.","family":"Ulm","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-1100525","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"204","DOI":"10.1227\/00006123-198602000-00017","article-title":"Variant aneurysms of the fenestrated basilar artery","volume":"18","author":"Andrews","year":"1986"},{"key":"b2-1100525","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"1005","DOI":"10.3171\/jns.1984.61.6.1005","article-title":"Saccular aneurysm associated with segmental duplication of the basilar artery.
