Carotid artery stenting (CAS) has emerged as an alternative treatment for carotid stenosis in patients poorly suited for endarterectomy. Intracerebral hemorrhage following carotid revascularization (endarterectomy, angioplasty, artery stenting) is rare and thought to be related to reperfusion injury in most cases. Early experience suggests an increased incidence of hemorrhage following CAS as compared to endarterectomy. In this study, data were obtained through a case report on an 80-year-old male patient with cerebral infarction. The 80-year-old hypertensive man developed sudden monoparesis in the left arm. He underwent CAS for 90% stenosis of the left proximal internal carotid artery. Brain CT after procedure showed acute hematoma with left posterior cerebral artery territorial hemorrhage, including the upper thalamus with extended intraventricular hemorrhage (IVH). Since this hemorrhage occurred in vascular territory unlikely to have been supplied by the treated artery, this case suggests that the mechanism of intracerebral hemorrhage following CAS may in some cases be different from hyperperfusion hemorrhage classically described following endarterectomy.
