Feasibility of simultaneous bilateral carotid artery stenting

Due to the progressive aging of the population, severe bilateral carotid stenosis has become a more frequent condition. On occasion, simultaneous revascularization may be appropriate. There is increased evidence that for these high-risk patients, a percutaneous revascularization may be the best approach. However, there are concerns that simultaneous bilateral carotid stenting may be associated with cerebral hyperperfusion, excessive bradycardia, and hypotension. We report a series of 10 consecutive patients who underwent simultaneous bilateral carotid stenting. All of these patients were not deemed to be surgical candidates due to high-risk comorbidities. All but one of the lesions were successfully stented. There were no procedural deaths, myocardial infarctions, or strokes. Thus, among carefully selected patients, simultaneous bilateral carotid artery stenting is a promising, technically feasible option.
