What type of scissors is used to perform an arteriotomy alongside the 11 blade?

The use of Potts scissors to perform an arteriotomy is appropriate due to their specific design, which allows for controlled, precise dissection of vascular tissues. Potts scissors, often used in vascular surgery, are specifically designed with a curved blade that enables surgeons to make clean incisions and facilitate access to the arterial lumen without damaging surrounding tissues or structures. This is particularly important during an arteriotomy, where maintaining the integrity of surrounding tissues while efficiently accessing the vessel is crucial.

Other instruments listed may have general surgical applications for cutting tissues but lack the specialized design that Potts scissors provide for vascular access. Metzenbaum scissors are typically used for cutting delicate tissues, whereas curved Mayo scissors are designed for cutting heavy tissues or fascia, making them less suitable for the precision required during an arteriotomy. Blunt surgical scissors may be used for certain tasks requiring less precision but would not provide the same efficacy in vascular procedures. Thus, Potts scissors are the most appropriate choice for conducting an arteriotomy alongside the 11 blade.
