Summary
Double infarct in one cerebral hemisphere, a specific stroke type, is linked to internal carotid artery stenosis. This condition presents unique neurological syndromes, distinguishing it from other acute ischemic strokes.
Area of Science:
- Neurology
- Cerebrovascular Diseases
- Stroke Etiology
Background:
- Double infarct in a single cerebral hemisphere is a distinct stroke pattern.
- Understanding its etiology and clinical presentation is crucial for diagnosis.
Purpose of the Study:
- To identify the etiological factors and clinical syndromes associated with double infarct in one cerebral hemisphere.
- To differentiate this specific stroke pattern from other acute ischemic strokes.
Main Methods:
- Retrospective analysis of 1,911 patients from the Lausanne Stroke Registry.
- Identification of 32 patients with first-ever double infarct in one cerebral hemisphere.
- Correlation of infarct territories, potential embolic sources, and internal carotid artery (ICA) status with clinical presentation.
Main Results:
- Double infarct involved territories of middle cerebral artery, posterior cerebral artery, lenticulostriate, anterior choroidal, or borderzone arteries.
- Common ICA stenosis (≥90%) or occlusion (75%) was observed.
- Specific syndromes like hemianopia-hemiplegia and aphasia variants were noted in nearly half of the patients.
Conclusions:
- Double infarct in one cerebral hemisphere is strongly associated with severe ICA stenosis or occlusion.
- Unique clinical syndromes arise from specific infarct combinations, warranting recognition.
- This distinct stroke pattern requires differentiation from other acute ischemic strokes for appropriate management.
