The question asks for the most appropriate post-procedure surveillance program to monitor the patient's condition. The options provided include various schedules for follow-up visits that assess symptoms, perform vascular examinations, and measure the Ankle-Brachial Index (ABI) or conduct arterial duplex imaging. The goal is to select a program that ensures thorough monitoring and timely intervention, reflecting best practices in vascular care."}
