Figure 4. DSA of ACom WNCA (pre- and postocclusion by BAC). A 49-year-old woman presented with subarachnoid hemorrhage. (A) DSA was done and revealed an ACom wide neck aneurysm, measuring 4.97 mm at the dome and 3.04 mm at the neck; DNR was 1.6. (B) Balloon remodeling during the coiling of WNCA. (C,D) Occlusion of a WNCA by BARISCT, classified as Raymond class 1. This classification indicates a successful procedure with no residual aneurysm filling, showcasing the effectiveness of the treatment approach.
DSA: digital subtraction angiography; ACom: anterior communicating artery; WNCA: wide-neck intracranial aneurysms; BAC: balloon-assisted coiling; BARISCT: balloon-assisted rapid intermittent sequential coiling technique; DNR: dome-to-neck ratio
