The clinical significance of artery of Percheron in cerebral ischemia: a summary overview

Abstract

The artery of Percheron (AOP) infarction is a rare vascular condition and a pattern of ischemia where a single arterial trunk supplies blood to the rostral midbrain and paramedian thalamic areas, causing neurological deficits. Due to its rarity and atypical presentation, AOP infarction is frequently overlooked in initial assessments, particularly on computed tomography (CT) scans. In addition, different types of AOP infarction have been identified, and it is shown that there can be four significant distinct types of this disease, which may manifest some different symptoms and have various vascular alterations. Knowledge of these variants in the AOP multisystem disorder is imperative to the diagnosis and treatment of infarctions in the condition, hence improving prognosis. To manage this uncommon but important condition, we need to increase awareness among healthcare providers and carry out more research on diagnosis and treatment.
