AI-generated Abstract

Objective: To determine the patterns of clinical presentation, lesion topography, and etiology in patients with ischemic stroke limited to the superficial territory of the posterior cerebral artery (s-PCA). Methods: In the Lausanne Stroke Registry (LSR, 1983-1998), we determined the patterns of clinical presentation, lesion topography and mechanisms of stroke among 117 patients with s-PCA infarction (s-PCAI) on brain imaging. Results: s-PCAIs accounted for 30.5 % of all PCA territory ischemic strokes. The presumed etiology was embolism in 54.5 % of patients, with neurological deficits predominating in visual fields. Neuropsychological dysfunction was significant, particularly in memory and language. Conclusions: s-PCAIs are uncommon, and while embolism is the main cause, identification of the source remains difficult, highlighting the need for thorough investigation of neuropsychological deficits.
