WebJan 19, 2024 · Transcarotid artery revascularization (TCAR) is a distinct hybrid approach to carotid stenting that requires surgical exposure of the common carotid artery at the base of the neck for stent deployment. TCAR uses dynamic flow reversal for cerebral protection. WebAug 19, 2024 · Importantly, embolic protection is accomplished by proximal carotid artery clamp placement and reversal of carotid artery blood flow (reversal-of-flow [ROF]) via an extracorporeal circuit from the carotid artery to the femoral vein.
