Transient coma as Percheron’s artery stroke
Abstract
The artery of Percheron is a rare anatomic variation in the brain vascularization, in which a single arterial trunk arises from the posterior cerebral artery to supply both sides of brain structures, i.e., the thalamus and midbrain. Occlusion of this uncommon vessel results in a characteristic pattern of bilateral paramedian thalamic infarcts with or without mesencephalic infarctions. We report the case of a Caucasian woman who completely recovers after transient coma due to Percheron artery infarction.
