  • Study
  • MCG and AU Health are among about 120 sites nationally enrolling nearly 2,500 participants in the study that will follow participants with 70 percent or greater blockage of one of their carotid arteries for four years. (scienmag.com)
  • MCG cardiothoracic and vascular surgeon Dr. Gautam Agarwal is performing the carotid endarterectomies at the Augusta center, where study participants are being randomized to one of the two treatment regimens. (scienmag.com)
  • stent
  • A stent is a metal mesh tube that is placed in the artery to keep it open. (drugs.com)
  • Then a stent is placed to reopen the artery. (lvhn.org)
  • A tiny, expandable stent is inserted into the newly opened area of the artery to help keep the artery from narrowing or closing again. (lvhn.org)
  • The stent is inserted via a catheter placed into the femoral artery in the groin and threaded through the blood vessels of the body to the area of the blockage. (nyp.org)
  • The stent is left permanently in the artery to provide a reinforced channel through which blood can flow. (nyp.org)
  • A balloon is inflated to open the artery and a small mesh tube, or stent, is inserted to maintain the opening. (dukehealth.org)
  • The artery heals around the stent. (dukehealth.org)
  • Blockage
  • The plaque fragment may get stuck in one of these smaller arteries, creating a blockage that cuts off blood supply to part of your brain. (mayoclinic.org)
  • Hearing a carotid bruit, the noise made by the blood flowing past an area of blockage, may indicate narrowing in the carotid system. (lahey.org)
  • Arteries in the neck and brain can be visualized, and the blockage can often be detected. (lahey.org)
  • blockages
  • Clinical trials are seeking to determine if patients with blockages in large arteries fare better if endovascular techniques - which employ devices inserted into the blocked artery through a catheter - are used. (nyp.org)
  • catheter
  • Once in place, the catheter injects a dye into the arteries. (harvard.edu)
  • It requires placing a catheter in the carotid artery to take X-rays of the vessel while dye is injected. (virginiamason.org)
  • TCAR (or transcarotid arterial revascularization) - With TCAR, a 1-2- centimeter incision is made above the collarbone to place a catheter into the carotid artery, which temporarily reverses the flow of blood away from the brain. (lvhn.org)
  • A special long, hollow tube (catheter) is inserted into the carotid artery to be treated. (lvhn.org)
  • The balloon is inflated once the catheter has been placed into the narrowed area of the carotid artery. (lvhn.org)
  • The catheter is inserted into the femoral artery in the groin and threaded up to the blocked artery in the brain, where the device is deployed. (nyp.org)
  • This minimally invasive procedure uses a catheter to access the carotid artery. (dukehealth.org)
  • This is an invasive imaging procedure that involves inserting a catheter into a blood vessel in the arm or leg, and guiding it to the carotid arteries with the aid of a special x-ray machine. (ausrad.com)
