Natural History of vertibrobasilar dolichoectasia
Vertibrobasilar dolichoectasia (VBD) is enlargement, elongation, and tortuosity of the basilar artery. Passero and Rossi have an article in the current issue of Neurology discussing the natural history of this condition. The outcomes from VBD ranges from completely asymptomatic to compression of the brainstem or cranial nerves, obstructive hydocephalus, ischemia in the vertibrobasilar artery distribution, and intracranial bleeds of various kinds. So the natural history depends on the condition at diagnosis and on its evolution. (Source: Passero SG and Rossi S. 'Natural history of verterbrobasilar dolichoectasia' Neurology, Jan 1, 2008.
