In PAD, which finding describes slow return of color after arterial occlusion and indicates delayed vascular filling?

• A. Prolonged capillary refill time
• B. Prolonged vascular filling time
• C. Normal skin temperature
• D. Rapid capillary refill

Answer: (B)

In assessing arterial perfusion, the speed with which color returns to tissue after removing an arterial occlusion shows how quickly blood re-enters the limb. Slow color return means the vascular network is filling slowly, i.e., there is delayed vascular filling due to reduced arterial inflow from the obstruction. This is why the description fits "prolonged vascular filling time" best. While prolonged capillary refill time can also indicate poor perfusion, the scenario described specifically refers to the time needed for the tissue to regain color after an arterial occlusion, which targets the vascular (arterial) inflow rather than the microcapillary refill alone. Rapid capillary refill would indicate normal perfusion, and normal skin temperature would not align with PAD-related delayed filling.
