[Treatment for intracranial aneurysms].

Aneurysm rupture is suspected in case of sudden, intense headache, sometimes associated with nausea or vomiting, focal neurologic deficit or loss of consciousness. Aneurysm rupture is a diagnostic and therapeutic emergency that has to be managed in highly specialized centers. Ruptured aneurysms have to be treated in emergency to avoid rebleeding. Endovascular approach is the first line treatment. The indications for treatment of unruptured have to be discussed according to several factors including patient's age, aneurysm size and location. Follow-up examinations are needed after aneurysm treatment (CTA, MRA, DSA). According to aneurysm risk factors, patients with aneurysms have to stop smoking and their blood pressure should be controlled on a regular basis and treated if needed.
