Abstract

Background: Intravenous recombinant tissue plasminogen activator (rt-PA) is the currently standard treatment of acute ischemic stroke within 4.5 hours of the onset of stroke. Recent studies have looked at the benefits of administration of intra-arterial (IA) rt-PA within 8 hours onset of symptoms. Our objective was to assess the outcome of stroke after administration of IA rt-PA in patients with acute ischemic stroke.Methods: We recruited 10 consecutive acute ischemic stroke patients with onset of stroke from 4.5 hours to 6.5 hours. The present study was conducted at Yashoda Hospital, Hyderabad, India, between January 2008 and December 2013. All patients underwent stroke subtyping and were administered rt-PA. We measured the thrombolysis in cerebral infarction (TICI) score after thrombolysis and functional outcomes at time of admission, after 24 hours, 30, 60, and 90 days.A good outcome was defined as modified Rankin Scale (mRS) ≤ 2 after 90 days.Results: Out of 10 patients 9 were men, mean age 56.3 ± 1.8 years and age range from 35-68 years. On stroke subtyping, 6 (60%) patients had large artery atherosclerosis, 3 (30%) had a stroke of indeterminate etiology and 1 (10%) had a stroke of other etiologies. Mean time of recanalization was 6.2 ± 0.5 hours,7 (70%) patients showed major neurological improvement with a mRS score of ≤ 2 at 90 days and one patient was lost to follow-up.Conclusion: Our study established good outcome at 90 days after administration of IA thrombolysis rt-PA in acute ischemic stroke.
