Objective : Endovascular mechanical thrombectomy has become a treatment option for acute ischemic stroke patients who
have contraindications for intravenous recombinant tissue plasminogen activator (rt-PA) or who missed the 4.5-hours
therapeutic window at Siriraj hospital. The purpose of the present study was to evaluate the initial result of the treatment
at Siriraj Hospital.
Material and Method: A retrospective review of all patients with acute ischemic stroke who underwent treatment by
endovascular mechanical thrombectomy at Siriraj Hospital from November 2009 to August 2012 was performed.
Results : There were 41 patients who had at least 30 day-period follow up. The mean age was 61.4±14.5 years. The initial
mean NIHSS was 19.4±5.52. Successful recanalization rate was documented in 92.7% of patients. Good clinical outcome
(modified Rankin Scale scores equal or lesser than 2) at mean 16-month follow-up time was found in 34.15%.
Conclusion : Endovascular mechanical thrombectomy is the option of treatment for large vessel acute ischemic stroke can
help rescuing those patients who have contraindications for intravenous rt-PA or who miss the golden time window.
