What is the role of clinical assessment in graft patency surveillance?

• A. Evaluate symptoms and physical findings such as pulse quality and limb perfusion
• B. Evaluate postoperative pain scores only
• C. No clinical assessment is needed
• D. Rely solely on imaging findings

Answer: (B)

Clinical assessment is the bedside gauge of whether a vascular graft is functioning well. By checking symptoms and performing a focused exam, you can detect changes in limb perfusion early. This means evaluating how the limb feels and functions—ask about claudication, rest pain, and color changes—and examining the limb for pulse quality, skin color and temperature, cap refill, perfusion, and edema. These signs directly reflect blood flow through the graft and can signal developing stenosis or occlusion before more dramatic problems occur.

Relying on pain scores alone misses many important clues. Pain can be influenced by many factors and may not correlate with graft flow, while some patients may have neuropathic pain or analgesia that masks ischemic symptoms. Imaging studies are crucial for confirmation and planning, but they don’t replace the real-time, functional information you get from a careful clinical exam. Regular clinical surveillance guides timely imaging and intervention, making it the cornerstone of graft patency surveillance.
