Objective: In the four-year period between January 2003 and December 2006, 75 patients with cerebral aneurysms treated in our Unit exclusively with embolization, were selected for follow-up study.

There were no limiting criteria for inclusion in the group selected, thus those included were patients who underwent embolization for aneurysms of any calibre, whether ruptured or not, in any dependant vessel of the Circle of Willis.

The follow-up over time required control angiography 6 months post-procedure followed by an AngioMRI every 6 moths thereafter to review the progress.

The incidence of revascularized aneurysmal re-bleeding within the six-month period immediately following the treatment was found to be just under 3%.

The present study was designed to determine, as much as possible, the causes for embolized aneurysmal re-bleeding in correlation to the following variables: the type aneurysm (ruptured or not); the site and dimension of the aneurysm; its complete or partial exclusion from the circulation after the endovascular treatment, and the medical treatment employed after the embolization.

In particular, we evaluated whether those patients, who presented with re-bleeding over time from the treatment would have had a different prognosis had they been treated with conventional surgical procedures and what the criteria should be to select patients as candidates either for surgery or for embolization.
