[Diagnosis and treatment of acute ischemic insults].

In cases of stroke a distinction is made between a transient ischemic attack (TIA), a manifest ischemic infarction and cerebral hemorrhage. Cerebral ischemia can be caused by large vessel disease, small vessel disease, embolic causes, rare causes or stroke of unknown etiology. Acute diagnostic tests include a neurological examination, computed tomography (CT) and/or magnetic resonance imaging (MRI) with angiography, electrocardiography (ECG), and laboratory tests. The basic treatment of patients with TIA or acute ischemic infarction is performed in the stroke unit and includes monitoring of respiratory function, cardiac function, treatment of potential heart failure, detection of swallowing disorders, prophylaxis of thromboembolism, control of blood pressure and elevated blood sugar levels, and lowering of elevated body temperature. In patients with cardioembolic infarction, oral anticoagulation is initiated depending on the severity of the stroke and the size of the stroke on imaging.
