A patient with carotid atherosclerosis asks the nurse to describe a carotid endarterectomy. Which response by the nurse is accurate?
a. "The obstructing plaque is surgically removed from an artery in the neck."
b. "The diseased portion of the artery in the brain is replaced with a synthetic graft."
c. "A wire is threaded through an artery in the leg to the clots in the carotid artery and the clots are removed."
d. "A catheter with a deflated balloon is positioned at the narrow area, and the balloon is inflated to flatten the plaque."
ANS: A
In a carotid endarterectomy, the carotid artery is incised and the plaque is removed. The response beginning, "The diseased portion of the artery in the brain is replaced" describes an arterial graft procedure. The answer beginning, "A catheter with a deflated balloon is positioned at the narrow area" describes an angioplasty. The final response beginning, "A wire is threaded through the artery" describes the mechanical embolus removal in cerebral ischemia (MERCI) procedure.
