Abstract
The authors report a novel stepwise carotid revascularization method to prevent perioperative complication. A 68-year-old man presented with left hemiparesis and dysarthria caused by severe stenosis of the right cervical internal carotid artery. According to the preoperative cerebral blood flow evaluation and plaque characterization, the patient was at risk for postoperative hyperperfusion and ischemic complications after carotid artery stenting. Initially, the patient underwent percutaneous angioplasty using an undersized balloon. Fifteen days later, the patient underwent a carotid endarterectomy. The surgical specimen obtained during the carotid endarterectomy showed the presence of typical vulnerable plaque. Of note was the complete preservation of the thin fibrous cap. The postoperative single-photon emission tomography images showed no signs of hyperperfusion, and the patient developed no neurological symptoms after each of the procedures.
