Abstract

Background and Purpose— To assess safety and efficacy data of a new bioactive coil (Cerecyte) which is loaded with polyglycolic acid on the inside of the coil.

Methods— Fifty-four patients harboring 55 aneurysms were treated with Cerecyte coils. These aneurysms were matched in localization and size with aneurysms treated with bare platinum coils.

Results— Periprocedural complications and handling did not differ between both groups. Initial aneurysm occlusion was comparable in both treatment groups. At 6 months angiographic follow-up, the aneurysms occluded with Cerecyte coils had a higher chance for complete occlusion (P=0.045) and tended to a lower retreatment rate (P=0.056).

Conclusions— Cerecyte coils are as safe as bare platinum coils in the endovascular occlusion of aneurysms. This matched pair analysis indicates a higher occlusion rate of aneurysms occluded with Cerecyte coils.
