BACKGROUND AND PURPOSE: The purpose of this study was to compare obtained packing densities of aneurysms treated with the newly introduced GDC 360° coils with packing densities of aneurysms treated with either complex Orbit/Trufill coils or helical GDC 10 coils.

PATIENTS AND METHODS: Twenty-two aneurysms in 20 patients were coiled with GDC 360° coils. For each of the 22 aneurysms coiled with GDC 360° coils, 2 volume-matched controls treated with either complex Orbit/Trufill coils or helical GDC coils were identified from our data base. The packing of these matched controls was compared with the calculated packing of the 22 aneurysms treated with GDC 360° coils.

RESULTS: There was no difference in mean aneurysm volume between aneurysms treated with any of the 3 types of coils (P = .9). Mean packing of 22.1% of aneurysms treated with GDC 360° coils was significantly lower than mean packing of 30.3% of aneurysms treated with complex Orbit/Trufill coils (P = .0015). Mean packing of 22.1% of aneurysms treated with GDC 360° coils was not different from mean packing of 21.6% of aneurysms treated with helical GDC 10 coils (P = .81).

CONCLUSION: The use of complex-shaped GDC 360° coils does not lead to increased packing in comparison with that of helical GDC 10 coils. The use of complex Orbit/Trufill coils results in significantly higher packing than that of both GDC 360° coils and helical GDC 10 coils.
