For every aneurysm treated with GDC 18 coils, we tried to identify a volume-matched control aneurysm treated with exclusively GDC 10 coils or exclusively Trufill/Orbit coils. This process resulted in 32 aneurysm pairs treated with either GDC 18 or GDC 10 coils and 35 aneurysm pairs treated with either GDC 18 or Trufill/Orbit coils.RESULTS: The mean packing of 24.2\% of aneurysms treated with GDC 18 was significantly higher than the mean packing of 18.3\% of aneurysms treated with GDC 10 (P \< .0001). The mean packing of 23.1\% of GDC 18 coils was not different from the mean packing of 25.1\% of Trufill/Orbit coils (P = .15).CONCLUSION: In aneurysms of 4 mm or larger, packing performance of helical GDC 18 coils is superior to that of helical GDC 10 coils and equal to that of complex Trufill/Orbit coils.}, issn = {0195-6108}, URL = {https://www.ajnr.org/content/28/7/1384}, eprint = {https://www.ajnr.org/content/28/7/1384.full.pdf}, journal = {American Journal of Neuroradiology} }
