Abstract:
In early thrombolytic therapy for acute focal ischemic stroke, the start of treatment within therapeutic time window is one of the most important thing. Recently, new imaging modalities such as SPECT, transcranial doppler, diffusion/ perfusion-weighted MRI, and MR anglography have been implicated to avoid time consumption and delayed therapy. Of these, MR angiography is nomnvasi and rapid technique to visualize large and medium-sized arteries. We explored the usefulness of MR angiography in early thrombolytic therapy. Arterial occlusion of three patients with severe ischemic stroke were demonstrated on MR anglography and wluch were treated with Urokmase (10, 000-20, 000 units/kg) by intravenous infusion within 2-4 hours after symptom onset. Recanalization and brain lesion was assessed by repeated MR angiography and MRI or CT 24 hours later. Clinical improvement was observed in two patients 5-24 hours after initiation of treatment. In one patient hemorrhagic infarction without clinical deterioration was detected by follow-up computed tomography. Recanalization was documented on repeated MR angiography of three patients. MR angiography can document occlusion of stroke-related vasculature without delay of thrombolytic therapy and repeated MR anglography can reveal whether recanalization has occurred.
