<h3>BACKGROUND AND PURPOSE:</h3> The endovascular treatment (EVT) of cerebral aneurysms has experienced a revolution since 1991 with the introduction platinum coil technology. During past 10 years, there been significant study feasibility this technique, and clinical results EVT have published. long-term durability Guglielmi detachable (GDC) embolization still remains unknown. purpose was to evaluate stability anatomic occlusion assess rate recanalization retreatment these aneurysms. <h3>MATERIALS METHODS:</h3> Between January 1998 December 2003, 1036 (804 ruptured 232 nonruptured) were treated consecutively GDC coils in 5 neuroradiology centers. Procedural feasibility, acute angiographic results, morbidity, mortality associated technique assessed. All patients regularly followed by digital subtraction angiography MR imaging each year after treatment. <h3>RESULTS:</h3> Initial demonstrated total 731 (70.5%), subtotal 252 (24.3%), incomplete 20 (1.9%), failures 33% (3.3%) A remodeling used 10%. second procedure performed for 72 (7%). aneurysm follow-up time 49,923 months (4160.25 aneurysm-years). period either following initial incompletely occluded or years due de novo Fewer than rebled during follow-up. Long-term angiograms obtained 899 aneurysms, 646 total, 230 subtotal, 23 results. <h3>CONCLUSIONS:</h3> is necessary depict recanalization. Only 7% retreated. Use bare gives good level occlusion.
