Which vascular procedure is listed as one where Arista is applied?

• A. Carotid Endarterectomy
• B. AV Fistula Creation
• C. Femoral Bypass or AAA Repair
• D. Renal Transplant

Answer: (C)

Arista AH is a topical hemostatic sponge-like powder used on bleeding vascular surfaces to promote rapid clot formation. It works by absorbing blood and concentrating platelets and clotting factors at the site, providing a scaffold for coagulation and helping achieve hemostasis when oozing is diffuse or difficult to pin down with sutures alone.

This makes it especially helpful in large vascular reconstructions where there are broad, raw surfaces, such as femoral bypass procedures or abdominal aortic aneurysm repairs. After the primary vessels are controlled and the graft anastomoses are fashioned, there can be diffuse oozing around the exposed beds. Applying Arista to those areas helps accelerate hemostasis, reduce blood loss, and shorten operative time, then the material is absorbed over time.

In other procedures listed, bleeding is typically managed with precise suturing, patching, or other techniques, and Arista is not as commonly highlighted as the standard hemostatic adjunct.
