abstract

IntroductIon  -  Innovative and breakthrough technologies  have emerged in the endovascular  management of brain aneurysms. Nevertheless, until recently, there has been a dearth of established techniques and studies pertaining aneurysms arising within the carotid  siphon of the internal carotid  artery. The authors review  their clinical experience and outline the current perspectives on the present  state of the art  in the management of carotid  siphon aneurysms. Methods -  Three hundred and eight internal carotid  artery siphon aneurysms were reviewed, encountered in 232 patients treated at two centers of Interventional Neuroradiology  in France (Rothschild and Beaujon), between February 2002 and May 2014. Aneurysms were divided into two groups, namely  I (those managed  until 2010), and II (those managed  after 2010). results -  The rate of endovascular aneurysm repair has significantly increased during the past 5 years since new medical devices were introduced. There was a predominance of the balloon-remodeling technique in group  I versus that of flow diverting devices in group II. conclusIons  -  The management of carotid siphon aneurysms has become notably safer using new endovascular techniques. More studies are required to compare  different endovascular  aneurysm repair techniques.
