Giant Vertebrobasilar Junction Aneurysms: 39 Patients
Thirty-nine giant aneurysms arose at the vertebralbasilar (V-B) junction. Twelve were illustrated and described previously (Fig. 13.1). Most probably had their origins from small aneurysms which usually arise at the proximal crotch of a fenestration at the beginning of the basilar artery. That the fenestration was seldom seen in angiograms was presumably because the expansion of the necks of these masses would obliterate the fenestration, although in three the remnant of the fenestration could be seen in the angiogram and/or at operation. Two patients had only one vertebral artery, the other ending in posterior-inferior cerebellar artery (PICA). In nine cases, the aneurysm was obviously fusiform, probably having origin from an unknown arteriopathy.
