The ankle-brachial index (ABI) was recorded for all patients before and after treatment. ABI is the ratio of maximum ankle systolic pressure to maximum brachial artery systolic pressure, with 0.9–1.3 for normal, 0.71–0.89 for mild ischemia, 0.5–0.7 for moderate ischemia, and <0.5 for severe ischemia.
