Patients who have atherosclerosis or hardening and narrowing of the arteries in their extremities may need an intervention to relieve symptoms. Symptoms include fatigue, pain, burning, numbness, tingling, swelling, and discolored skin or ulcers in the affected extremity.
When medications are not effective, a surgical intervention may be needed. The first option is angioplasty. This is when a physician inserts a catheter into the artery and uses a balloon to open up the blockage.
