[What is Confirmed in the Treatment of Ischemic Stroke]

Ischemic stroke is one of the leading causes of death worldwide and the most frequent cause of permanent disability in adulthood. The acute treatment of stroke is time-critical and, according to the time is brain principle, it is important to determine as soon as possible whether recanalization treatment that can save the penumbra is possible. Intravenous thrombolysis (IVT) and, if a large vessel occlusion is identified, endovascular treatment (EVT) possibly in combination with IVT, are recommended. Further treatment in a stroke unit is another important component of acute stroke treatment. The best secondary preventive treatment must already be initiated in the acute phase. The cause of stroke guides making decisions on the ideal secondary preventive strategy. The most important etiologies of stroke are cardiac embolism, atherosclerotic macroangiopathy and cerebral microangiopathy (small vessel disease). Less frequent causes are dissections of arteries supplying the brain or vasculitis. In up to 20-30% of all cases, however, no clear etiology can be determined despite intensive investigation of the cause. This means corresponding uncertainty in the optimal secondary prevention that consists in particular of an anticoagulant medication adapted to the etiology, treatment of cardiovascular risk factors and if necessary surgical or interventional desobliterative procedures. This article describes the diagnostic procedure and the evidence-based treatment of ischemic stroke.
