Randomized Controlled Trial Multicenter Study Clinical Trial
Combined intravenous and intra-arterial r-TPA versus intra-arterial therapy of acute ischemic stroke: Emergency Management of Stroke (EMS) Bridging Trial.
The purpose of this study was to test the feasibility, efficacy, and safety of combined intravenous (IV) and local intra-arterial (IA) recombinant tissue plasminogen activator (r-TPA) therapy for stroke within 3 hours of onset of symptoms. ⋯ This pilot study demonstrates combined IV/IA treatment is feasible and provides better recanalization, although it was not associated with improved clinical outcomes. The presence of thrombus on initial arteriography was directly related to the baseline NIHSSS. This approach is technically feasible. The numbers of symptomatic ICH were similar between the 2 groups, which suggests that this approach may be safe. Further study is needed to determine the safety and effectiveness of this new method of treatment. Such studies should address not only efficacy and safety but also the cost-benefit ratio and quality of life, given the major investment in time, personnel, and equipment required by combined IV and IA techniques.

Randomized Controlled Trial Multicenter Study Clinical Trial
A randomized efficacy trial of citicoline in patients with acute ischemic stroke.
Citicoline (cytidine-5'-diphosphocholine; CDP-choline) may reduce central nervous system ischemic injury by stabilizing cell membranes and reducing free radical generation. A previous dose-comparison trial in patients with acute stroke found that 500 mg of citicoline appeared to improve neurological outcome with minimal side effects. ⋯ The results of this study indicate that citicoline was safe but ineffective in improving the outcome of patients with acute ischemic stroke who were enrolled in this trial. Post hoc analyses indicate that there may be a subgroup of patients with moderate to severe strokes who would benefit.
