Peripheral aneurysms usually develop in the popliteal artery that runs down the lower part of the thigh and knee. Although it doesn’t occur as commonly as the other types of aneurysm, it can also develop in the arteries the supply blood to the kidneys or bowels, and in arteries of the arms or neck.
Unlike aortic aneurysms, peripheral aneurysms are not likely to rupture, but will often form blood clots that may block blood flow to the arms, legs or brain. Some of the warning signs to watch out for are:
Cramping in the legs with exercise or claudication
Pain in the arms or legs even during rest
Numbness or pain radiating in the leg or arm
A throbbing lump that can be felt in the neck, arm, leg or groin
Sore fingers or toes that don’t heal
Gangrene or tissue death
