which may present as subarachnoid hemorrhage. In this situation, treatment
is controversial. Case report - A case of intracranial right vertebral art
ery dissection in a 55-year-old woman presenting with subarachnoid hemorrha
ge is reported. The patient underwent therapeutic occlusion of the dissecte
d artery through microcatheterization using pushing detachable platinum mic
rocoils and had a good outcome. At this moment, the patient has a normal ne
urologic examination and a control digital subtraction angiography 1 year a
fter the procedure showed an occluded right vertebral artery at V3; there w
as retrograde flow in the right intracranial vertebral artery up to the ori
gin of a meningeal branch; the artery was thin and had mural irregularities
