Question

which of the following surgical procedures removes an obstruction from one of the major arteries of the neck?
a cerebrospinal fluid shunt
b laminectomy
c carotid endarterectomy
d nerve block

Explanation:

• Cerebrospinal fluid shunt: It is used to treat conditions related to cerebrospinal fluid (like hydrocephalus), not arterial obstructions.
• Laminectomy: Removes part of the vertebra (lamina) to relieve pressure on the spinal cord or nerves, not for arterial issues.
• Carotid endarterectomy: Specifically removes plaque (obstruction) from the carotid artery (a major neck artery) to improve blood flow to the brain.
• Nerve block: Involves injecting medication near a nerve to relieve pain, not for removing arterial obstructions.

Answer:

C. carotid endarterectomy
