Current experience of the treatment of multiple cerebral aneurysms (literature review)

Multiple cerebral aneurysms are found in one among four patients with aneurysmal subarachnoid hemorrhage. Nowadays, there is no clear consensus regarding the optimal treatment of multiple cerebral aneurysms. The papers published up to December 2021 containing the results of endovascular treatment of multiple cerebral aneurysms. Treatment strategy, surgical methods, complications associated with the procedure, and mortality rates were analyzed. The treatment of multiple cerebral aneurysms remains an unresolved problem of vascular neurosurgery, in particular, there is no consensus on the optimal method of treatment and timing. Current evidence-based data indicate the advantage of minimally invasive techniques in the treatment of multiple cerebral aneurysms due to the low risk of complications and the possibility of one-session procedure. The question of treat or not to treat of unruptured aneurysms in the presence of multiple aneurysms is a matter of debate. The choice between surgical methods (microsurgical clipping or endovascular coiling) or observation requires a multidisciplinary approach, taking into account the risks of rupture and the corresponding procedures.
