Résumé : Intracranial aneurysm treatment began in the 20th century. Treatment remained anecdotal for a long time because these lesions could not be visualized. This was the period of hunterian ligation of the carotid and trapping. After the discovery of the carotid angiography at the end of the 1920s, a new direct clipping approach started. Other techniques were used, such as wrapping and coating. Finally, in the 1980s, endovascular procedures appeared and are now in constant progress. The advantages, problems and improvements of these treatments are briefly reviewed. © 2008 Elsevier Masson SAS. All rights reserved.
