A series of 62 patients treated surgically for one or several unruptured intracranial aneurysms is reported. 83 aneurysms were treated in 65 operations. The main locations of the aneurysms were: MCA 35%, ICA (posterior communicating) 22%, carotido-ophthalmic segment 12%, carotid bifurcation 11%, anterior communicating artery 11%, verterbro basilar artery 5%. The circumstances of discovery were: incidental 28%, multiple aneurysm 22%, headache 18%, ischemic episode 9%, mass effect 8%, seizures 6%. ⋯ The authors' opinion now is surgical clipping of small and middle-sized aneurysms in young patients, without severe associated pathology, and clearly agreeing with surgery. The limit of age for surgery is usually 65 years except for those aneurysms discovered after a mass-effect. Elderly patients, giant aneurysms, patients with contra-indication for surgery, are proposed for endovascular treatment.
