Surveillance of Lower Extremity PAD After Revascularization (Duplex/ABI)
| Indication | Appropriate Use Score (1–9) | |||
|---|---|---|---|---|
| 123. | • Baseline surveillance (within 1 month) | A (8) | ||
| New or Worsening Symptoms | ||||
| 124. | • After revascularization (angioplasty ± stent or bypass) | A (9) | ||
| Asymptomatic or Stable Symptoms | ||||
| Asymptomatic or Stable Symptoms After Baseline Study, Surveillance Frequency During First Year | At 3 to 5 months | At 6 to 8 months | At 9 to 12 months | |
|

| 125. | • After angioplasty ± stent placement | I (2) | U (6) | U (6) |
| 126. | • After vein bypass graft | U (6) | A (8) | U (6) |
| 127. | • After prosthetic bypass graft | U (5) | A (7) | U (5) |
| Asymptomatic or Stable Symptoms After Baseline Study, Surveillance Frequency After First Year | Every 6 months | Every 12 months | Every 24 months or greater | |

| 128. | • After angioplasty ± stent placement | I (3) | A (7) | U (5) |
| 129. | • After vein bypass graft | U (5) | A (7) | U (5) |
| 130. | • After prosthetic bypass graft | I (3) | A (7) | U (5) |
A = appropriate; I = inappropriate; PAD = peripheral artery disease; U = uncertain.
