The goal in this study was to report the results of endovascular treatment of ACoA aneurysms in these patients.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>The aneurysms were managed with an endovascular approach in which detachable coils were used. A brief anatomical description of the ACoA and its branches as well as a review of the surgical and endovascular literature is presented. The \u201cACoA Syndrome\u201d (that is, amnesia and personality changes), which may occur after subarachnoid hemorrhage, is briefly reviewed and described. Recent technical developments that can lead to improved results are also discussed.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>Of the 306 aneurysms, 268 (87.5%) were small, 30 (10%) were large, and 8 (2.6%) were giant. One hundred ninety-three aneurysms (63%) had a small neck, whereas 113 (37%) had a wide neck. Sixty-five lesions (21%) were incidental, 5 (2%) presented with symptoms of mass effect, and 236 (77%) presented with a subarachnoid hemorrhage. A complete aneurysm occlusion was attained in 139 cases (45.5%), a neck remnant was detected in 145 (47.5%), and in 22 cases (7%) a residual filling of the aneurysm was observed. Regarding the clinical neurological outcome, 280 patients (91.5%) remained neurologically intact, improved, or unchanged from their initial clinical status. Two large, wide-necked, subtotally occluded aneurysms ruptured 3\u20137 months after the procedure, with subsequent death of the patients. The procedure-related morbidity and mortality rates were 3.5% (11 cases) and 1% (3 cases), respectively.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>The inherently lower risk of injuring or occluding the delicate branches and perforating vessels arising from the ACoA makes the endovascular approach attractive, interesting, and elegant.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2008.10.jns081005","type":"journal-article","created":{"date-parts":[[2009,1,30]],"date-time":"2009-01-30T14:55:51Z","timestamp":1233327351000},"page":"874-879","source":"Crossref","is-referenced-by-count":29,"title":["Endovascular treatment of 306 anterior communicating artery aneurysms: overall, perioperative results"],"prefix":"10.3171","volume":"110","author":[{"given":"Guido","family":"Guglielmi","sequence":"first","affiliation":[{"name":"Division of Interventional Neuroradiology, University of California at Los Angeles, California; and"},{"name":"Division of Neuroradiology, San Camillo Hospital, Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fernando","family":"Vi\u00f1uela","sequence":"additional","affiliation":[{"name":"Division of Interventional Neuroradiology, University of California at Los Angeles, California; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gary","family":"Duckwiler","sequence":"additional","affiliation":[{"name":"Division of Interventional Neuroradiology, University of California at Los Angeles, California; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Reza","family":"Jahan","sequence":"additional","affiliation":[{"name":"Division of Interventional Neuroradiology, University of California at Los Angeles, California; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Enrico","family":"Cotroneo","sequence":"additional","affiliation":[{"name":"Division of Neuroradiology, San Camillo Hospital, Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Renato","family":"Gigli","sequence":"additional","affiliation":[{"name":"Division of Neuroradiology, San Camillo Hospital, Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-1100874","series-title":"Neurology","doi-asserted-by":"publisher","first-page":"752","DOI":"10.1212\/WNL.34.6.752","article-title":"Amnesia after anterior communicating artery aneurysm rupture","volume":"34","author":"Alexander","year":"1984"},{"key":"b2-1100874","series-title":"Eur Neurol","doi-asserted-by":"publisher","first-page":"37","DOI":"10.1159\/000047945","article-title":"Neuropsychological sequelae of patients treated with microsurgical clipping or endovascular embolization for anterior communicating artery aneurysms","volume":"47","author":"Chan","year":"2002"},{"key":"b3-1100874","series-title":"Stroke","doi-asserted-by":"publisher","first-page":"272","DOI":"10.1161\/01.STR.8.2.272","article-title":"The anterior communicating artery has significant branches","volume":"8","author":"Crowell","year":"1977"},{"key":"b4-1100874","series-title":"Acta Neurochir Suppl (Wien)","doi-asserted-by":"publisher","first-page":"42","DOI":"10.1007\/978-3-7091-9183-5_8","article-title":"Unilateral interhemispheric keyhole approach for anterior cerebral artery aneurysms","volume":"53","author":"Fukushima","year":"1991"},{"key":"b5-1100874","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"561","DOI":"10.3171\/jns.2000.93.4.0561","article-title":"Natural history of the neck remnant of a cerebral aneurysm treated with the Guglielmi detachable coil system","volume":"93","author":"Hayakawa","year":"2000"},{"key":"b6-1100874","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"1211","DOI":"10.1097\/00006123-199706000-00019","article-title":"Comment in: Serizawa T, Saeki N, Yamaura A: Microsurgical anatomy and clinical significance of the anterior communicating artery and its perforating branches","volume":"40","author":"Heros","year":"1997"},{"key":"b7-1100874","series-title":"Radiat Med","first-page":"291","article-title":"Endovascular treatment of anterior cerebral artery aneurysms using Guglielmi detachable coils: mid-term clinical evaluation","volume":"20","author":"Kazekawa","year":"2002"},{"key":"b8-1100874","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"629","DOI":"10.1227\/00006123-198312000-00001","article-title":"Causes of unfavorable outcome after early aneurysm operation","volume":"13","author":"Ljunggren","year":"1983"},{"key":"b9-1100874","series-title":"Acta Neurochir (Wien)","doi-asserted-by":"publisher","first-page":"78","DOI":"10.1007\/BF01809337","article-title":"Branches of the anterior communicating artery.
