Abstract |
Reperfusion of the ischemic brain is the most effective therapy for salvage of penumbral tissue in acute ischemic stroke. However, only a few patients are eligible for thrombolytic therapy due to time limit or other unavoidable contraindications for the treatment in spite of the presence of salvageable tissue. Several small clinical studies have shown that pharmacologically induced blood pressure elevation may improve neurological deficits in acute ischemic stroke, presumably by augmenting blood flow to penumbral brain tissue. We report a patient with acute ischemic stroke who showed successful recovery of neurologic deficit after therapeutic induced hypertension. A 69 years old man presented with acute ischemic stroke due to atherothrombotic occlusion of right internal carotid artery. Initial cranial MRI showed significant perfusion-diffusion mismatch. The patient showed progressive deterioration despite intravenous thrombolysis. Induced hypertension therapy with phenylephrine was started to
increase cerebral blood flow to ischemic brain tissue. Affer elevation of blood pressure, the patient's condition recovered markedly. There was no complication associated with induced hypertension. Drug induced hypertension therapy can be helpful in selected patients with acute ischemic stroke who had perfusion-diffusion mismatch on MRI due to severe stenosis or occlusion of large cerebral arteries. |
