Recently, I have treated several patients who have intermittent claudication as a common feature. They have visited multiple hospitals, neurology, orthopedics, pain medicine, and endocrinology, but the symptoms of intermittent claudication could not be relieved or even worsened. Thankfully, these patients eventually found the vascular surgery department, and after careful examination, the dorsalis pedis artery was found to be weakened or the pulsation disappeared. Ultrasound and CT arteriography of the lower extremity arteries were performed, and more or less narrowing or occlusion of the lower extremity arteries was found. Then how to treat it? At present, vascular surgery treatment has traditional surgery and interventional surgery to open the blood vessels to improve the blood supply of lower extremity arteries. The symptoms of intermittent claudication in these patients who have undergone specialist treatment have improved significantly.
