Object. The primary goal of this matched-pair analysis was to evaluate the durability of the treatment results with Cerecyte coils in comparison with that of bare platinum coils in terms of angiographic occlusion rates at follow-tip. Methods. Eighty aneurysms treated with Cerecyte coils were included in this study to carry out a matched-pair analysis. Every aneurysm treated with Cerecyte coils was matched with an aneurysm treated with bare platinum coils. Matching of the aneurysms was done according to the aneurysm size, location, neck size, initial occlusion grade, and clinical presentation. Results. The initial treatment results were similar in both groups as part of a matching protocol. Subgroup analysis revealed a significant difference in the durability of occlusion in aneurysms that showed Raymond Class 1 obliteration on follow-up angiograms (69 [86.2%] in the Cerecyte group vs 51 [63.8%] in the control group. p = 0.002). Further thrombosis to Raymond Class I occlusions was higher in the Cerecyte group (17 [77.3%] of 22 vs 8 [36.4%] of 22 aneurysms). Conclusions. Cerecyte coils provide further thrombosis and more durable results than bare platinum coils following coil embolization of cerebral aneurysms. (DOI: 10.3171/2009.8.JNS081372)
