title: Carotid stump syndrome: A case report.
abstract: Carotid stump syndrome (CSS) is known to be one of the causes of recurrent ipsilateral ischemic stroke following the occlusion of the internal carotid artery (ICA). The present study describes a case of left CSS in a 50-year-old patient presenting with a central retinal artery embolism following internal carotid and middle cerebral artery occlusion. The central retinal artery embolism was believed to be a consequence of microemboli, which originated from the stump of the occluded ICA, passing into the ophthalmic artery due to external carotid-internal carotid anastomotic channels, although the other possible pathophysiological causes of this condition are discussed. Digital subtraction angiography of the patient showed trickle flow in the occluded ICA during the venous phase, by which the stump emboli may have been transported to the ophthalmic artery. The patient was successfully treated with anticoagulation therapy without surgical or endovascular treatment.
