Aneurysm neck plane
Reduction in area-averaged velocity (%)	8.1±4.3	20.5±15.4	0.016
Reduction in maximum velocity (%)	−2.1±12.2	5.4±16.1	0.240
Residual neck
Reduction in averaged velocity (%)	29.4±13.3	42.9±23.7	0.219
Reduction in maximum velocity (%)	15.5±17.3	25.5±19.9	0.370
Reduction in WSS (%)	10.0±16.7	16.0±18.2	0.400
Aneurysm dome
Reduction in averaged velocity (%)	86.1±12.5	81.9±25.7	0.766
Reduction in maximum velocity (%)	62.8±46.1	82.5±27.6	0.533
