1. We suggest that patients treated with open or endovascular interventions for IC be monitored with a clinical surveillance program that consists of an interval history to detect new symptoms, ensure compliance with medical therapies, record subjective functional improvements, pulse examination, and measurement of resting and, if possible, postexercise ABIs (Grade 2, Level C).
2. We suggest that patients treated with lower extremity vein grafts for IC be monitored with a surveillance program that consists of clinical follow-up and duplex scanning (Grade 2, Level C).
3. We suggest that patients who have previously undergone vein bypass surgery for IC and have developed a significant graft stenosis on DUS be considered for prophylactic reintervention (open or endovascular) to promote long-term bypass graft patency (Grade 1, Level C).

ABI, Ankle-brachial index; DUS, duplex ultrasound.
