Comparative study for ruptured aneurysms treated by surgery and endovascular method

The management of intracranial aneurysms has truly evolved after the introduction of the endovascular treatment. In this paper we compare patients that were operated or embolized for intracranial aneurysms. Between 1995 and 1999, 78 grade I to III ruptured aneurysms were treated in our service: 52 patients were operated, 21 were embolized and 5 were submitted to combinated endovascular and surgical treatment. In the surgical group, clinical outcome was very good in 80.8% of cases with 5% of mortality with 96.2% of total exclusion of the aneurysm. In the endovascular group, 95% of cases the clinical outcome was very good with only 42.8% of total exclusion of the aneurysm. By the endovascular method for treatment of aneurysms, we can obtain a good clinical outcome but a poor radiological outcome and sometimes need a complementary surgical procedure to treat residual aneurysm.
