Prediction of Cerebral Hyperperfusion After Carotid Artery Stenting by Cerebral Angiography and Single-Photon Emission Computed Tomography Without Acetazolamide Challenge COMMENT

摘要

The authors performed a retrospective study of patients undergoing an initial carotid artery stenting (CAS) procedure for carotid artery stenosis. It was their intent to demonstrate the utility of singlephoton emission computed tomography (SPECT) in correlation with the patient’s cerebral angiogram to assess the risk of cerebral hyperperfusion syndrome. Their findings were that preoperative asymmetry index (AI) on the SPECT and leptomeningeal anastomosis predicted cerebral hyperperfusion phenomenon (CHP); and CHP occurred in all case of cerebral hyperperfusion syndrome.
