Or acute limb ischemia, is a blood clot in an artery, which can be very serious because it can stop blood reaching important organs.

Blood clots form when platelets (blood components) and plasma proteins thicken, forming a semisolid mass. Arterial clots block blood and oxygen from reaching your vital organs. They can lead to tissue damage.

Often, they occur in your legs and feet. Sometimes, they happen in your brain, where they can lead to stroke. They could also form in your heart, where they can cause a heart attack.
Arterial clots can also take root in your kidneys, intestines, or eyes, though this is rare.

Symptoms:

– Could be absent
– Cold arm or leg
– Muscle pain or spasm in the affected area
– Numbness or tingling in your arm or leg
– Weakness of the affected limb
– Loss of color in the affected limb
