Ischemic stroke is most often due to embolic occlusion of large cerebral vessels; source of emboli may be heart allergy solutions discount 4mg aristocort overnight delivery, aortic arch allergy treatment products order aristocort visa, or a more proximal arterial lesion allergy medicine ear pressure purchase discount aristocort on line. Primary involvement of intracerebral vessels with atherosclerosis is less common than in coronary vessels allergy medicine for 7 year old cheap aristocort on line. Hemorrhage most frequently results from rupture of aneurysms or small vessels within brain tissue. Clinical Presentation Ischemic Stroke Abrupt and dramatic onset of focal neurologic symptoms is typical of ischemic stroke; with hemmorhage, deficits typically evolve more slowly and drowsiness is common. Variability in stroke recovery is influenced by collateral vessels, blood pressure, and specific site and mechanism of vessel occlusion. Intracranial Hemorrhage Vomiting occurs in most cases, and headache in about one-half. Stroke needs to be distinguished from potential mimics, including seizure, tumor, migraine, and metabolic derangements. Acute Ischemic Stroke Treatments designed to reverse or lessen tissue infarction include: (1) medical support, (2) thrombolysis, (3) antiplatelet agents, (4) anticoagulation, and (5) neuroprotection. Medical Support Immediate goal is to optimize perfusion in ischemic penumbra surrounding the infarct. Blood pressure should never be lowered precipitously (exacerbates the underlying ischemia), and only in the most extreme situations should gradual lowering be undertaken. Osmotic therapy with mannitol may be necessary to control edema in large infarcts, but isotonic volume must be replaced to avoid hypovolemia. Only a small percentage of stroke pts are seen early enough to receive treatment with this agent. Nearly 50% of pts die; prognosis is determined by volume and location of hematoma. Neurosurgical consultation should be sought for possible urgent evacuation of cerebellar hematoma; in other locations, evacuation is usually not helpful. Treatment for edema and mass effect with osmotic agents and induced hyperventilation may be necessary; glucocorticoids not helpful. If a hypercoagulable state is suspected, further studies of coagulation are indicated. For suspected cardiogenic source, cardiac ultrasound with attention to right-to-left shunts, and 24-h Holter monitoring indicated. Primary and Secondary Prevention of Stroke Risk Factors Atherosclerosis is a systemic disease affecting arteries throughout the body. Hypertension and diabetes are also specific risk factors for lacunar stroke and intraparenchymal hemorrhage. Embolic Stroke In pts with atrial fibrillation, the choice between warfarin or aspirin prophylaxis is determined by age and risk factors (Table 18-6). If an embolic source cannot be eliminated, anticoagulation is usually continued indefinitely. For patients who "fail" one form of therapy, many neurologists recommend combining antiplatelet agents with anticoagulation. Anticoagulation Therapy for Noncardiogenic Stroke In contrast to cardiogenic stroke, there are few data to support long-term warfarin for preventing atherothrombotic stroke. Surgical Therapy Carotid endarterectomy benefits many pts with symptomatic severe (70%) carotid stenosis; the relative risk reduction is 65%.
