Transfemoral carotid artery stenting (TFCAS) was introduced as a less invasive option for carotid revascularization in patients at high risk for complications from carotid endarterectomy (CEA). The increased perioperative stroke and death risk of TFCAS has however prevented TFCAS from widespread acceptance as an alternative to CEA in high-risk patients. Recent research suggests that transcarotid artery revascularization (TCAR) may be associated with a low stroke and death risk and potentially meet the needs of patients at high surgical risk. We aimed to estimate the 30-day risk of stroke or death of TCAR and compare it to TFCAS and CEA. ⋯ Among patients undergoing TCAR with dynamic flow reversal for carotid stenosis the 30-day risk of stroke or death was low. The perioperative stroke/death rate of TCAR was similar to that of CEA while CNI risk was lower. Larger prospective studies are needed to account for confounding factors and provide higher certainty.
