In the originally published version of this manuscript, the terms “complete occlusion” and “adequate occlusion” were used differently than by other authors1,2 interpreting the WEB occlusion scale.3 In the preexisting WEB literature, complete occlusion has been defined as complete occlusion with or without an angiographically visible collection of contrast within the marker recess (WEB Occlusion Scale A or B). Adequate occlusion is defined to include these cases as well as cases with residual neck filling (WEB Occlusion Scale A, B, or C). Accordingly, in the originally published version of this manuscript, the term “adequate occlusion” should be termed “complete occlusion” and adequate occlusion should be understood to include aneurysms with neck remnants. These inconsistencies with the published literature have now been corrected.
