During a carotid endarterectomy, which instrument is most appropriate for elevating plaque?

The Freer is the most appropriate instrument for elevating plaque during a carotid endarterectomy. This instrument is specifically designed to provide the surgeon with the ability to carefully elevate the plaque from the arterial wall without causing excessive trauma to the surrounding tissue. The shape and rigidity of the Freer make it well-suited for this task, allowing for precision and control.

In contrast, scissors are typically used for cutting rather than elevating plaque, which requires a different approach. Forceps generally provide a grasping mechanism but do not have the intended design for safe plaque elevation, and their use may lead to inadvertent tearing of the artery. The clearance scraper is more aligned with removing debris rather than specifically lifting plaque, making it less appropriate for this particular task during a carotid endarterectomy. Therefore, the Freer stands out as the most effective choice for this procedure.
