When BPD was performed, we showed that before BPD, 77% of patients had a VD-AR > 17%, and the other patients (VD-AR ≤ 17%) (23%) would not require BPD. This finding is important, since BPD is associated with higher rate of cerebrovascular events compared to the patients without BPD. 8,22 Avoiding unnecessary BPD would possibly reduce the risk of cerebrovascular events as well as procedural costs. Moreover, most cases of VD-AR ≤ 17% before BPD were found in Sellers’ II, suggesting that the visual assessment of the Sellers’ classification could lead to unnecessary PBD.
