- Abstract
- "Background : Our previous pilot study demonstrated that intravenous recombinant tissue plasminogen activator(rt-PA)
fibrinolytic therapy was effective in treatment of effects of acute ischemic stroke within 3 hours of onset. We stud-ied
whether rt-PA was effective and safe in patients with acute carotid artery territory ischemic stroke with severe neu-rologic
deficits (National Institute of Health Stroke Scale (NIHSS) score >14 points) and whether arterial recanalization
after rt-PA infusion influenced the initial neurologic improvements within 24 hours and the stroke outcome at 3 months.
Methods
: Twenty eligible patients had pre- and post-treatment computed tomogram and pre-treatment magnetic reso-nance
angiogram. Fourteen patients had post-treatment magnetic resonance angiogram at 24 hours after stroke onset.
Endpoints examined included initial neurological improvement at 2 and 24 hours by NIHSS and clinical stroke outcome
at 3 months by a modified Rankin scale and the effect of recanalization on initial improvement and stroke outcome.
Results
: Out of 20 patients, 9 patients (45%) showed initial improvement at 2 hours and 10 patients (50%) at 24 hours.
Five patients (25%) had intracranial hemorrhages (symptomatic; 2). Twelve patients (60%) showed good clinical stroke
outcome at 3 months. Complete or partial recanalization was observed in 11 patients (55%) at 24 hours after stroke
onset. Recanalization correlated with good initial improvement and stroke outcome (p<0.05 and <0.05). Conclusions :
Recanalization may have an association with good clinical outcome after rt-PA infusion within 3 hours of stroke onset
in patients with acute carotid artery territory stroke with severe neurologic deficits.Key Words : Cerebral ischemia, Thrombolytic therapy, Recanalization, Plasminogen activator, Tissue-type, Stroke out-come"
