    Abstract:
    Among the 1052 patients admitted to our hospital because of cerebral infarction between January 1, 2007, and December 31, 2010, we report the treatment outcomes of 48 patients (4.6% of all patients) who received recombinant tissue plasminogen activator (rt-PA) therapy (simultaneously combined with edaravone) within 3 hours after the onset of infarction. Twenty (41.7%) patients started receiving edaravone before rt-PA administration, and 28 patients (58.3%) started receiving rt-PA and edaravone simultaneously. The patients had an average age of 73.5 years (range, 55-93 years; male:female, 32:16). Medical histories included hypertension, diabetes mellitus, dyslipidemia, arterial fibrillation, and a smoking history in 23 (47.8%), 7 (14.6%), 8 (16.7%), 29 (60.4%), and 8 (16.7%) of patients, respectively. Regarding the treatment outcome of the therapy, the National Institutes of Health Stroke Scale score, which was 15 points before rt-PA administration, showed a statistically significant improvement to 8 points after rt-PA administration (P < .001). The modified Rankin Scale scores at 90 days after treatment were as follows: 0 in 12 patients (25.0%), 1 in 11 patients (22.9%), 2 in 7 patients (14.6%), 3 in 5 patients (10.4%), 4 in 6 patients (12.5%), 5 in 5 patients (10.4%), and 6 in 2 patients (4.2%). The occluded blood vessel reopened completely in 30 patients (62.5%) and partially in 5 patients (10.4%). Asymptomatic hemorrhage over the entire brain developed in 2 patients (4.2%). Thus, rt-PA therapy in combination with edaravone improved the recanalization rate, reduced the incidence of intracranial hemorrhage, and improved functional prognosis.
