The aim of this study is to consider the results of the aneurysms treated in our unit in the last years. The results of a given treatment are very difficult to evaluate if a series of prior assumptions have not been made, i.e., the goals of treatment, patient selection, and so on. This is particularly true if alternative treatments are available and if, as in the present work, the cases are recruited over a relatively long time with respect to the time of evolution of the technique.
Two techniques were used, occlusion of the parent vessel with secondary thrombosis of the aneurysm and selective occlusion of the aneurysm with coils.
