Bilateral thalamus stroke due to percheron artery

Abstract

Bilateral thalamus ischemic stroke is a rare condition that carries significant morbidity and mortality in comparison to other forms of stroke. It is usually associated with an anatomical variant with the thalamic paramedian arteries arising from a common trunk from the posterior cerebellar artery, known as Percheron artery. This infarct is difficult to be recognized and early recognition of this syndrome improves survival and functional recovery. We report a case of bilateral thalamic stroke after cardiac surgery.
