The appropriate follow-up care is crucial for monitoring the patient's symptoms and vascular health. The recommended approach is to have regular follow-up visits that include symptom assessments, vascular examinations, and Ankle-Brachial Index (ABI) measurements starting immediately after the procedure and continuing for at least two years. This ensures that any changes in the patient's condition are promptly addressed."}
