The carotid arteries are located in the neck and serve the important function of supplying blood to the neck, head, and brain. Carotid artery disease occurs when fatty deposits, or plaque, builds up within the inner walls of these arteries leading to partial or complete blockages. The consequences can be life-threatening. MCI cardiologists specialize in an innovative hybrid procedure called transcarotid artery revascularization or TCAR in which blockages are opened by stent.
