Surgical clipping was reserved for cases excluded from CE or cases in which CE failed. The study consisted of 103 consecutive patients with 132 aneurysms, of which 127 were treated. Coil embolization was performed using Guglielmi detachable coils, and surgery was performed using Zeppelin clips. Three groups were defined: Group A consisted of 64 aneurysms that were treated by CE (neck\/sac ratio &lt; 1:3); Group B, 63 aneurysms that were surgically clipped; and Group C, 12 aneurysms that failed to be satisfactorily (\u2265 95%) embolized and were subsequently clipped. The percentages of residual aneurysm were 31.2% in Group A, 1.6% in Group B, and 0% in Group C. The percentages of patients with poor Glasgow Outcome Scale (GOS) scores (GOS Scores 1\u20133) were 13.3% in Group A, 6.1% in Group B, and 8.3% in Group C. The percentages of poor outcome (GOS Scores 1\u20133) in patients with good clinical status before treatment were 10.7% in Group A, 0% in Group B, and 8.3% in Group C.<\/jats:p><jats:p content-type=\"fine-print\"><jats:italic>Conclusions.<\/jats:italic> Even with preselection, CE remains associated with a significant number of treatment failures and poor outcomes, even in patients with good preoperative clinical status. Surgical clipping can offer better results than CE, even for more complex aneurysms of the anterior circulation, especially for those involving the middle cerebral artery cases. However, because CE can be effective and causes less stress and invasiveness for the patient, it should be considered first in aneurysms strictly selected by a neurovascular team.<\/jats:p>","DOI":"10.3171\/jns.2000.93.2.0175","type":"journal-article","created":{"date-parts":[[2009,5,13]],"date-time":"2009-05-13T17:27:54Z","timestamp":1242235674000},"page":"175-182","source":"Crossref","is-referenced-by-count":102,"title":["Prospective analysis of aneurysm treatment in a series of 103 consecutive patients when endovascular embolization is considered the first option"],"prefix":"10.3171","volume":"93","author":[{"given":"Christian","family":"Raftopoulos","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pierre","family":"Mathurin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dutcho","family":"Boscherini","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rudolf F.","family":"Billa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michel Van","family":"Boven","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philippe","family":"Hantson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"445","DOI":"10.1016\/0090-3019(84)90449-X","article-title":"Analysis of 223 ruptured intracranial aneurysms with special reference to rerupture.","volume":"21","author":"Aoyagi","year":"1984"},{"key":"b2","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"98","DOI":"10.1016\/S0090-3019(97)00263-2","article-title":"The future of neurovascular surgery.
