Abstract
Background: the main symptoms of a compromise to the internal carotid artery are monocular blindness and those which are secondary to the lesion of the medial cerebral and anterior cerebral arteries.
Methods: a 79 year old male patient, with past medical history of diabetes and high blood pressure and clinical symptoms of compromise to the left medial cerebral artery. The patient shows an acute occlusion of the left internal carotid artery with arterial infarcts in the choroidal anterior and cerebral posterior territories in the same side of the carotid lesion. The cardioembolic source of the infarct was documented.
Conclusion: Although acute obstruction of the internal carotid artery is mostly associated with visual symptoms and engagement of the anterior circulation, it may also be associated with infarcts of the posterior cerebral artery.
