Transcarotid artery revascularization (TCAR) with the ENROUTE transcarotid neuroprotection and stent system (Silk Road Medical, Inc, Sunnyvale, Calif) combines surgical principles of neuroprotection with less invasive endovascular techniques to treat high grade stenosis in the carotid artery. The ENROUTE Neuroprotection System allows the surgeon to directly access the common carotid artery to initiate high rate temporary blood flow reversal to protect the brain while performing carotid angioplasty and stenting. Unprotected catheterization of the arch and lesion is, thus, avoided. Pivotal data from the Safety and Efficacy Study for Reverse Flow Used During Carotid Artery Stenting Procedure (ROADSTER) study of high-risk patients undergoing TCAR have showed a low stroke rate compared with other prospective trials of endovascular carotid intervention. The aim of this article is to provide specific technical details of TCAR.
