Drip-and-Ship Thrombolytic Therapy for Acute Ischemic Stroke.

BACKGROUND Neuroendovascular therapy is a common treatment for patients with acute ischemic stroke of the anterior circulation who fail to respond to recombinant tissue plasminogen activator. However, although most hospitals can provide recombinant tissue plasminogen activator therapy, many cannot perform neuroendovascular therapy. Thus, use of a drip-and-ship treatment-liaison system allowing recombinant tissue plasminogen activator-treated patients to be transferred to facilities offering neuroendovascular therapy is important. METHODS We retrospectively analyzed 16 drip-and-ship patients transferred to our hospital for additional neuroendovascular therapy after they received intravenous recombinant tissue plasminogen activator at prior hospitals between June 2009 and March 2017. RESULTS The mean patient age was 68 ± 17 years. Ten patients had cardiogenic embolism and 6 had atherothrombosis. Additional neuroendovascular therapy was performed in 14 patients. Median National Institute of Health Stroke Scale and diffusion-weighted image-Alberta Stroke Program Early Computed Tomography Scores before recombinant tissue plasminogen activator therapy were 14 and 8, respectively. Occluded or stenotic lesions of the cerebral arteries were detected by magnetic resonance angiography in the internal carotid artery (n = 4), middle cerebral artery (n = 10), and basilar artery (n = 3) (1 patient had tandem lesions). Mean intervals from onset-to-recombinant tissue plasminogen activator, recombinant tissue plasminogen activator-to-our hospital (door), door-to-puncture, and onset-to-recanalization were 166, 65, 32, and 334 minutes, respectively. No patients showed symptomatic intracranial hemorrhage. CONCLUSIONS Magnetic resonance imaging/angiography performed in previous hospitals allows initiation of reperfusion therapy immediately after transfer. Thus, drip-and-ship plus neuroendovascular therapy is a safe and useful system for treatment of patients with acute infarcts.
