Capillary refill >10 seconds in the hand with the graft may indicate which condition?

• A. Graft infection
• B. Normal healing
• C. Adequate perfusion
• D. Circulatory compromise or STEAL syndrome

Answer: (D)

Capillary refill time reflects distal blood flow. When refill is normal, the hand quickly pinks up after pressing the nail bed; a refill time well over a couple of seconds is concerning, and a value as high as 10 seconds indicates significant distal ischemia. In a hand with a dialysis graft, this pattern most likely points to circulatory compromise from steal syndrome, where arterial blood is preferentially diverted into the graft and away from the hand. The result is reduced perfusion to the hand, causing a cool, pale, possibly painful or numb extremity with weak or absent distal pulses.

This contrasts with graft infection, which would present with systemic or local inflammatory signs such as fever, redness, warmth, swelling, or drainage, and with normal healing or adequate perfusion, which would show a normal capillary refill. Because this finding signals compromised distal perfusion, it requires prompt assessment and intervention to restore blood flow and prevent further ischemic injury.
