TCAR Surveillance Project

The TCAR Surveillance Project (TSP) is an initiative of the Society for Vascular Surgery Patient Safety Organization (SVS PSO). The TSP is a surveillance registry designed to monitor the safety and effectiveness of transcarotid stents placed directly into the carotid artery while reversing blood flow within the carotid artery to reduce stroke risk. It will compare this less-invasive surgical procedure with standard carotid endarterectomy in centers that participate in the Vascular Quality Initiative (VQI).


  • Obtain more data about real-world outcomes of TCAR in comparison with CEA as performed by centers participating in the VQI.
  • Serve as a repository for TCAR precedures and outcomes data to broaden the evidence base for TCAR.
  • Benchmark outcomes against other participants.

“I believe that more clinicians should more widely adopt the TCAR technology as it has been demonstrated to be safe and effective and seems to be an excellent alternative to CEA.”

“Our overall findings showed that while patients receiving TCAR were sicker and more likely to be symptomatic with a higher degree of stenosis, the stroke and death rate compared to CEA was the same.

“With TCAR, there were significantly lower cranial nerve injuries, less time spent in the operating room and fewer patients with a prolonged length of stay.
