Which documentation best describes a properly functioning arteriovenous graft (AV graft)?

• A. Thrill present and palpated.
• B. Bruit heard at the graft site.
• C. Distal pulses absent.
• D. Redness and warmth around graft site.

Answer: (A)

Assessing AV graft patency through palpation findings. A properly functioning AV graft should have a palpable thrill along the graft, which is a vibrating sensation felt over the access site as blood moves rapidly through the artificial conduit. This thrill indicates that there is ongoing flow through the graft, meaning the graft is not narrowed or occluded. Documenting that the thrill is present and can be palpated provides a clear, objective sign of patency. While a bruit heard over the graft can also suggest flow, it is less definitive for documentation because sounds can be variable due to technique, frequency, or ambient factors, and a bruit alone may not always reliably confirm patency. Absence of a thrill raises concern for stenosis or thrombosis and would prompt further evaluation. Redness and warmth around the graft point more toward irritation or infection rather than functioning flow. Therefore, noting that a thrill is present and palpated best reflects a functioning AV graft.
