The results led the authors to consider replacing conventional angiography with 3D-CT angiography for use in diagnosing ruptured aneurysms, and to perform surgery aided by 3D-CT angiography alone without conventional angiography. Based on the results, 100 consecutive patients with SAH who had undergone surgery in the acute stage based on 3D-CT angiography findings have been studied since December 1996. One hundred ruptured aneurysms, including 41 associated unruptured lesions, were detected using 3D-CT angiography. In seven of 100 ruptured aneurysms, which included four dissecting vertebral artery aneurysms, two basilar artery (BA) tip aneurysms, and one BA\u2014superior cerebellar artery aneurysm, 3D-CT angiography was followed by conventional angiography to acquire diagnostic confirmation or information about the vein of Labb\u00e9, which was needed to guide the surgical approach for BA tip aneurysms. All of the ruptured aneurysms were confirmed at surgery and treated successfully. Ninety-three patients who underwent operation with the aid of 3D-CT angiography only had no complications related to the lack of information gathered by conventional angiography. The 3D-CT angiography studies provided the authors with the aneurysm location as well as surgically important information on the configuration of its sac and neck, the presence of calcification in the aneurysm wall, and its relationship to the adjacent vessels and bone structures.<\/jats:p>\n<jats:p content-type=\"fine-print\"><jats:italic>Conclusions<\/jats:italic> The authors believe that 3D-CT angiography can replace conventional angiography in the diagnosis of ruptured aneurysms and that surgery can be performed in almost all acutely ruptured aneurysms by using only 3D-CT angiography without conventional angiography.<\/jats:p>","DOI":"10.3171\/jns.2001.94.5.0718","type":"journal-article","created":{"date-parts":[[2009,5,13]],"date-time":"2009-05-13T17:37:45Z","timestamp":1242236265000},"page":"718-727","source":"Crossref","is-referenced-by-count":103,"title":["Three-dimensional computerized tomography angiography\u2014guided surgery of acutely ruptured cerebral anuerysms"],"prefix":"10.3171","volume":"94","author":[{"given":"Masato","family":"Matsumoto","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masanori","family":"Sato","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masayuki","family":"Nakano","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuji","family":"Endo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Youichi","family":"Watanabe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatsuya","family":"Sasaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyouichi","family":"Suzuki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Namio","family":"Kodama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"AJNR","first-page":"1571","article-title":"Evaluation of the circle of Willis with three-dimensional CT angiography in patients with suspected intracranial aneurysms.","volume":"16","author":"Alberico","year":"1995"},{"key":"b2","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"1315","DOI":"10.1097\/00006123-199912000-00008","article-title":"Computed tomographic angiography versus digital subtraction angiography for the diagnosis and early treatment of ruptured intracranial aneurysms.","volume":"45","author":"Anderson","year":"1999"},{"key":"b3","series-title":"AJNR","first-page":"1113","article-title":"Cerebral aneurysms: detection and delineation using 3-D-CT angiography.","volume":"13","author":"Aoki","year":"1992"},{"key":"b4","series-title":"Radiology","doi-asserted-by":"publisher","first-page":"129","DOI":"10.1148\/radiology.192.1.8208924","article-title":"Intracranial aneurysms: depiction on MR angiograms with a multifeature-extraction, ray-tracing postprocessing algorithm.","volume":"192","author":"Atlas","year":"1994"},{"key":"b5","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"230","DOI":"10.1227\/00006123-199501000-00037","article-title":"Early experience with spiral CT in the diagnosis of intracranial aneurysms.","volume":"36","author":"Dorsch","year":"1995"},{"key":"b6","series-title":"J Neurosurg","first-page":"985","article-title":"Report of World Federation of Neurological Surgeons Committee on a Universal Subarachnoid Hemorrhage Grading Scale.","volume":"68","author":"Drake","year":"1988"},{"key":"b7","series-title":"AJR","doi-asserted-by":"publisher","first-page":"247","DOI":"10.2214\/ajr.142.2.247","article-title":"Complications of cerebral angiography prospective assessment of risk.","volume":"142","author":"Earnest","year":"1984"},{"key":"b8","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1227\/00006123-198001000-00001","article-title":"Relation of cerebral vasospasm to subarachnoid hemorrhage visualized by computerized tomographic scanning.","volume":"6","author":"Fisher","year":"1980"},{"key":"b9","series-title":"Stroke","doi-asserted-by":"publisher","first-page":"1649","DOI":"10.1161\/01.STR.24.11.1649","article-title":"Impact of early surgery on outcome after aneurysmal subarachnoid hemorrhage.
