Changes in brain substance perfusion after internal carotid artery stenting

Cerebrovascular diseases are nowadays one of the leading causes of incidence and lethality on our planet. Stenoses of the main arteries of the head and neck are considered to be one of the main causes of cerebral circulation ischemic disturbances. Angioplasty with stenting is the treatment of choice when repairing stenoses of internal carotid arteries. However, up to now only the repair of a vessel lumen was taken into consideration while evaluating this technique because of the lack of methods to analyze the blood flow in the brain substance itself. In vivo evaluation of cerebral circulation has been made possible by the advent of computed perfusion tomography. The purpose of this paper is to evaluate the changes in the brain substance of patients with stenoses of one of carotid arteries after stenting.
