Figure 3. Sequential WNCA occlusion by BAC of the same patient. (A) BAC was selected to obstruct the WNCA. The intraprocedural angiography confirmed that the aneurysm was entirely occluded following the deployment of detachable coils. (B) The full blockage of a WNCA, categorized as Raymond class 1. This rating demonstrates the efficacy of the treatment strategy by indicating a successful surgery with no remaining aneurysm filling.
WNCA: wide-necked cerebral aneurysm; BAC: balloon-assisted coiling
