Coil embolization of intracranial aneurysms is the first choice treatment in many centres worldwide. The ISAT study reported in favour of endovascular treatment even though coil embolization carries a higher risk of revascularization than surgical clipping. Bioactive coils boosting fibrosis within the aneurysm and neointimal production could counteract the tendency of embolized aneurysms to re-open. We reviewed our cohort in a retrospective study based on the following inclusion criteria: 1) Cerecyte coils (Micrus Endovascular, San Jose, Calif) were the only bioactive coils deployed. 2) Cerecyte coils were used in the first embolization procedure. Between July 2005 and December 2007 39 patients matched these inclusion criteria, 15 men and 24 women (average age 63.5 years) with 44 aneurysms. Treatment outcomes were: 30 aneurysms completed excluded from the circulation, 13 aneurysms almost completed excluded from the circulation, one incomplete aneurysm occlusion. Two aneurysms out of 44 recurred during follow-up (4.54%) and were re-embolized. The radio-opacity and conformational memory of the Cerecyte coils were satisfactory and they were easy to manoeuvre and detach.
