The treatment of hypertension with acute ischemic stroke
is controversial due to decrease mean arterial pressure
may reduce cerebral blood flow to already ischemic
regions and result in further ischemic injury after
intake of antihypertensive drugs. Our findings suggested
that there is a rapid adaptation of the cerebral
hemisphere and brain stem to antihypertensive therapy in
order to protect those areas of the brain from
hypoperfusion; however, an acute reduction in BP may
compromise cerebellar perfusion at the initial stage of
antihypertensive therapy in patients with hypertension.
3D pCASL can be used for monitoring cerebral blood flow
during antihypertensive therapy.
