Arterial bifurcation

The bifurcation of an aneurysm represents preferred locations for aneurysm formation, especially when they are associated with variations in divider geometry.

The Cerebral arteries (CAs) bifurcations do not represent regions of decreased artery wall strength 1).

Tütüncü et al., hypothesized a link between basilar apex aneurysms and basilar artery bifurcation (a) and vertebrobasilar junction (VBJ) angles 2)
