Each of the arteries in the lower limbs divides into two arteries in the upper thigh: one is the superficial femoral artery (SFA), which carries blood into the leg and foot past the knee, while the other, the deep femoral artery, supplies the thigh muscles.<\/span><\/p>\n<p><span style=\"font-size: 20px;\">If the superficial femoral artery is occluded or narrowed, cramps may develop in the leg muscles during walking or running. It usually begins mildly (although acute blockage will cause instant pain) as pain after walking a few blocks and worsens into pain after walking less than one block &#8211; if the stenosis or occlusion is not relieved. Much depends on the state of the arteries above and below the SFA.<\/span><\/p>\n<p><span style=\"font-size: 20px;\">This 75-year-old man\u2019s primary care doctor referred him to my clinic because of left leg cramps after ambulating a few blocks and\u00a0I found that his left superficial femoral artery was occluded (left column images).
