During a carotid endarterectomy, what instrument would the surgeon most likely need after using a #11 blade to make an incision?

The correct answer involves understanding the specific needs of a carotid endarterectomy procedure directly following the incision phase. After using a #11 blade to make an incision, the surgeon typically requires an instrument that can facilitate careful dissection and manipulation of the tissue. Potts-Smith scissors are specifically designed for this purpose and can effectively handle delicate tissues while allowing for controlled cutting.

In the context of a carotid endarterectomy, where precision and care are critical, Potts-Smith scissors are particularly useful for cutting through the adventitia of the carotid artery. They provide the surgeon with the necessary control to avoid damage to surrounding structures while facilitating access to the area where plaque removal occurs.

Other instruments listed, such as scalpel handles, are not required immediately following the incision since the incision has already been made. Metzenbaum scissors could be used for further dissection but are generally more suited for softer tissue rather than the specific vascular context of the carotid endarterectomy. A needle holder, while essential for suturing, would not be used until the closure phase of the procedure. Thus, the choice of Potts-Smith scissors aligns with the specific needs of the surgical process that follows the initial incision.
