Summary
Anterior circulation ischemic stroke, the most common stroke type, presents varied symptoms. Advances in diagnosis and acute management are improving patient outcomes.
Area of Science:
- Neurology
- Vascular Neurology
- Stroke Medicine
Background:
- Ischemic stroke in the anterior circulation, supplied by the carotid artery system, is the most prevalent type.
- Clinical presentations vary widely depending on the specific vascular territories affected.
- These strokes range from small lacunar infarcts to large territory infarctions, such as those involving the middle cerebral artery.
Purpose of the Study:
- To summarize the clinical spectrum of anterior circulation ischemic strokes.
- To highlight the role of diagnostic imaging in identifying these strokes.
- To discuss recent and anticipated advances in acute stroke management.
Main Methods:
- Review of clinical manifestations based on vascular territories.
- Emphasis on the utility of computed tomography (CT) and magnetic resonance imaging (MRI) for diagnosis.
- Discussion of current and emerging therapeutic strategies for acute ischemic stroke.
Main Results:
- Anterior circulation strokes exhibit diverse clinical syndromes correlating with affected brain regions.
- CT and MRI are crucial for accurate localization and assessment of stroke extent.
- Recent therapeutic advancements have significantly impacted acute stroke care.
Conclusions:
- Understanding the vascular territories is key to recognizing anterior circulation stroke syndromes.
- Advanced neuroimaging techniques are indispensable for diagnosis.
- Ongoing research promises further improvements in the acute management of ischemic stroke.
