Extracranial carotid artery stenting (CAS) represents a viable alternative for high-risk surgical patients. The aim of this study was to determine the clinical features and outcome of 25 patients that underwent CAS at the Puerto Rico Medical Center.A retrospective review of a series of 25 high-risk surgical patients that underwent CAS from June 2005 to January 2010 was performed. Patients were followed-up at clinics with computed tomography angiography and/or digital subtraction angiography.Patient ages ranged from 52 to 88 years. Twenty-one of the patients had severe cervical carotid stenosis (more than 80%). Those with moderate stenosis (from 50% to 80%) were treated when they were symptomatic or when stenosis recurred after carotid endarterectomy. Among the 25 patients, only 2 presented with restenosis (more than 50% luminal diameter). Both had a history of radiation-induced disease, but neither required retreatment. Five patients required post-stenting angioplasty due to a less than 50% improvement in luminal diameter. There was 1 death, and 1 patient presented delayed neurocognitive deterioration. The combined long-term morbidity and mortality in the subgroup with at least two years of follow-up was 8.3%. There were no intracerebral hemorrhages or recurrent strokes/transient ischemic attacks.The restriction of post-stenting angioplasty to only those cases without significant revascularization appears to help reduce restenosis rates while ensuring a gradual increase in intracranial blood flow. The latter may not apply to patients with a prior history of radiotherapy. |
