What does arterial occlusion look like on your toe?

Depends on the cause: Blue toe syndrome, also called trash foot, is a blue to black discoloration of the toes due to lack of blood flow. The most common cause is when a small piece of arterial plaque breaks off in the abdominal aorta-iliac-formal arterial system (stomach and groin areas) during angiography, cardiac, foot or vascular surgery. It also occurs in conjunction with diabetes, scleroderma and raynauds.

Varying colors.: If the arterial occlusion is higher up the leg, the toes may appear pale, red, or even blue, depending on the degree of blockage. If a small clot or piece of plaque breaks off and blocks one of the small arteries to a single toe, the toe will look dark blue or purple.
