Blockage in the artery causes pain in the fingers and knee-calf, what is this?

Blocked artery?: Can't make sense of this. Blockage of an artery can cause pain in the distribution of that artery, but there is no artery common to the fingers AND the knee calf except the aorta - blockage there would be catastrophic. Acute blockage causes ischemia (sudden pain as tissue dies) and chronic blockage produces pain (claudication) which increases with activity.
