Anatomy of the Posterior Cerebral Artery
Subspecialty: Neuro-anatomy
Type: Clinical Summary
The posterior cerebral artery (PCA) is the principal artery supplying the occipital lobes, inferomedial temporal lobe, thalamus, midbrain and choroidal/ventricular structures; its anatomy, segmental organization, and numerous perforating branches underpin both ischemic syndromes and surgical risk in the posterior circulation. This review provides a detailed microsurgical and functional description of PCA segments (P1–P4), major branches (central perforators, choroidal/ventricular and cortical branches), common anatomic variants (including fetal origin and communicating artery hypoplasia), and …
