Unruptured intracranial aneurysms in patients with transient cerebral ischemic episodes. Optional managements and literature review

Clinical experience about the management of patients with an unruptured intracranial aneurysm (UIA) presenting transient cerebral ischemic attacks (TIAs) is usually restricted to a few case reports. Some authors assume tha it is safe to perform an endarterectomy without acutely increasing the risk of aneurysm rupture while others reported a post-operative aneurysmal bleeding even for aneurysms smaller than 10 mm between some days and several months after endarterectomy. The aim of this paper is to analyse the factors involved in the particular ischemic episodes, the examination methods to be employed, and the optional management for each individual case on a literature review and own experience-based data.
