The application of fast multiparametric protocol MRI-based thrombolysis with rt-PA hyperacute cerebral infarction.

摘要

OBJECTIVE: To investigate the value of fast multiparametric protocol magnetic resonance imaging (MRI)-based thrombolysis in hyperacute cerebral infarction. METHODS: Seventy-seven patients with acute ischemic stroke were examined by multiparametric protocol MRI and among them, 12 patients with hyperacute cerebral infarction were treated by recombinant tissue plasminogen activator (rt-PA) and followed up periodically by MRI. RESULTS: The 12 patients selected by FMPMRI to receive thrombolysis demonstrated clinical improvement, with 90 day modified Rankin scale scores (mRs) < or = 2 and life quality Barthel index (BI) of 80-100. The only complication involved one patient (8.3%) who developed an asymptomatic intracranial hemorrhage 3 weeks after receiving thrombolytics. CONCLUSION: Multiparametric protocols have significant clinical potential for the treatment of hyperacute stroke patients who are candidates for receiving intravenous thrombolytic therapy. Our data suggest that patients suffering from hyperacute ischemic cerebral infarction that are strong candidates for intravenous thrombolytic therapy can be identified by multiparametric protocol MRI, especially to those whose time windows were undefined or beyond 3 hours after symptom onset.
