Rationale
The 2024 ACC/AHA/SVS PAD guideline (PMID 38752899) supersedes the 2016 AHA/ACC guideline Gerhard-Herman MD, Gornik HL, Barrett C, et al for all PAD management recommendations covered in Tables 5.2 and 5.3. Per stale guideline replacement rules, Gerhard-Herman MD, Gornik HL, Barrett C, et al has been replaced by Writing Committee Members in each affected claim rather than co-cited alongside it. The stale Aboyans V, Ricco JB, Bartelink M-LEL, et al citation in Table 5.2 has been replaced by ESVS Guidelines on the Management of Aneurysmal Disease (the current European guideline) to maintain geographic balance without retaining an outdated source. Article 2 (PMID 30497565) is a 2018 guideline comparison piece and does not add incremental value beyond what the primary guidelines already provide; it has not been cited. Article 3 (PMID 40193537) is a correction notice to the 2024 guideline and was flagged; no independent citation is warranted for a correction notice — the primary guideline citation Writing Committee Members covers the corrected content.

Approximately 30% of patients with popliteal aneurysms have acute ischemic symptoms at initial evaluation.
