Widening of the basilar bifurcation angle: association with presence of intracranial aneurysm, age, and female sex.


OBJECT Arterial bifurcations represent preferred locations for aneurysm formation, especially when they are associated with variations in divider geometry. The authors hypothesized a link between basilar apex aneurysms and basilar bifurcation (α) and vertebrobasilar junction (VBJ) angles. METHODS The α and VBJ angles were measured in 3D MR and rotational… (More)
