Summary

Objectives: To assess the implementation of intravenous rt-PA[1] in routine clinical care at our center after its formal approval in Israel, and the therapeutic and logistic implications for reperfusion therapy for acute ischemic stroke in Israel.

Methods: Patients with acute ischemic stroke, admitted between January 2005 and June 2006, who were treated with intravenous rt-PA or endovascular-based reperfusion were reviewed. Implementation, timing, safety and clinical outcomes were assessed.

Results: Forty-six patients received reperfusion therapy (37 with intravenous rt-PA and 9 with endovascular-based therapy), corresponding to 4.0% of ischemic stroke patients in 2005 and a projection of 6.2% in 2006. Mean age of intravenously treated patients was 67 years (range 22–85 years), median baseline NIHSS score was 14 (range 10–18, 25–75%) and the median ‘onset to drug time’ was 150 minutes (range 120–178, 25–75%). Symptomatic intracerebral hemorrhage and orolingual angioedema each occurred in one patient (2.7%). Significant clinical improvement occurred in 54% of treated patients and 38% of patients were independent at hospital discharge.

Conclusions: Use of reperfusion therapy for acute ischemic stroke has increased in our center after the formal approval of rt-PA therapy to over 5%, with ‘onset to drug time’, safety and outcome after intravenous rt-PA treatment comparing favorably with worldwide experience. A prerequisite for the implementation of effective reperfusion therapy and expansion of the proportion of patients treated nationwide is the establishment of a comprehensive infrastructure.
