In a PTFE upper arm graft, which artery serves as the inflow?

• A. Brachial artery
• B. Radial artery
• C. Ulnar artery
• D. Axillary artery

Answer: (A)

In an upper arm PTFE graft, the inflow artery is the brachial artery because it provides the main high-flow conduit at a suitable level for an arteriovenous graft. The brachial artery is large enough to supply the graft with ample arterial flow and is readily accessible for the proximal anastomosis. The radial and ulnar arteries are smaller, distal vessels not ideal as inflow for an upper arm graft. The axillary artery is not the typical inflow site for this configuration, since the graft is positioned to connect with the brachial artery.
