Decoding Altered Consciousness: An Artery of Percheron Stroke

The artery of Percheron (AOP) is a unique variant of the thalamic and midbrain perforating arteries. It originates from the P1 branch of the posterior cerebral artery (PCA) and supplies the bilateral paramedian thalami (BPT) along with variable contributions to the rostral midbrain. Four infarction...

Description
Summary:The artery of Percheron (AOP) is a unique variant of the thalamic and midbrain perforating arteries. It originates from the P1 branch of the posterior cerebral artery (PCA) and supplies the bilateral paramedian thalami (BPT) along with variable contributions to the rostral midbrain. Four infarction patterns have been identified as a result of an AOP stroke, each associated with varying prognostic outcomes. We present an 89-year-old female with an AOP infarction and discuss the associated symptoms, implicated anatomy, and prognosis.
