Intravenous Recombinant Tissue Plasminogen Activator Therapy for Acute Ischemic Stroke: Initial Israeli Experience

    Summary

    Background: Intravenous recombinant tissue plasminogen activator therapy within 3 hours of stroke onset is a proven effective treatment for acute ischemic stroke.

    Objectives: To assess the feasibility and safety of rt-PA[1] therapy for reperfusion in routine clinical practice in Israel, in a setting of a dedicated stroke unit.

    Methods: Consecutive patients presenting within less than 3 hours of stroke onset were evaluated by an emergency physician and the neurology stroke team. After brain computerized tomography eligible patients were treated with intravenous rt-PA (0.9 mg/kg; maximum dose 90 mg) according to an in-hospital protocol corresponding to recommended criteria. Patients were admitted to the acute stroke unit. Safety and clinical outcome were routinely assessed. Re-canalization was assessed by serial transcranial Doppler.

    Results: The study group comprised 16 patients, mean age 61 years (range 47–80 years), male to female ratio 10:6, whose median baseline National Institutes of Health stroke scale was 13 (range 6–24). They were treated within a mean door-to-CT time of 39 minutes (range 17–62 min), door-to-drug time 101 minutes (range 72–150), and stroke onset-to-drug time 151 minutes (range 90–180). There was an early improvement within 24 hours (of ≥ 4 points in the NIHSS[2] score) in 7 patients (44%) and no early deteriorations. There were no protocol deviations, no symptomatic intracranial hemorrhages, and no major systemic hemorrhage within 36 hours of rt-PA treatment. Three asymptomatic hemorrhagic transformations of the infarct were noted on routine follow-up brain CT associated with neurologic improvement. Outcome data were comparable to the National Institute of Neurological Disorders and Stroke rt-PA Stroke Study.

    Conclusion: Intravenous rt-PA treatment within 3 hours of stroke onset in routine clinical practice in Israel is feasible and appears safe in the setting of a neurology stroke unit and team. Careful implementation of rt-PA therapy for selected patients in Israel is encouraged.
