Resumo
Dissecting aneurysms of cerebral arteries are unusual causes of stroke. The
carotid system is the commonest site of this pathology, the vertebral arteries are less involved
and dissection of the basilar artery is rtare. The authors report three cases of arterial dis-
section of the vertebrobasilar system, two of the vertebral arteries and one of the basilar
artery. An extensive review of the literature is presented. The clinical picture of dissection
of vertebrobasilar system was inespecific but pain was a prominente symptom, though had
not occurred in the site of the arteries involved. The pain was suggestive of subarachnoid
hemorrhage. Associated or risk factors were mild trauma, migraine and high blood pressure.
The angiographic findings were suggestive, however just the «double lumen» has been con-
sidered pathognomonic. The prognosis is variable. It was benign in case 3, left sequela in case
2, and case 1 rebleed fatally.
