闭塞性周围动脉病和它的并发症是常见的临床问题。而动脉粥样硬化为最常见的原因。近年来,无创性方法学利用多普勒效应检测血流仪器的发展,有助于了解功能性血管腔内经并对诊断提供了客观指标。过去记载,间歇性跛行常在行走时发生与心绞痛常在劳力后发作,休息可使两者缓解的特征是一致的。间歇性跛行的症状因人而异,可表现为:下肢乏力软弱、抽筋、疼痛,麻木或这些症状的综合表 Occlusive peripheral arterial disease and its complications are common clinical problems. Atherosclerosis is the most common cause. In recent years, noninvasive methodology using the Doppler effect to detect the development of blood flow instrumentation helps to understand functional intravascular lumen and provides objective measures of diagnosis. It has been documented in the past that intermittent claudication often occurs when walking and angina often attacks after exerting labor. The characteristics of rest that ease both are consistent. Symptoms of intermittent claudication vary from person to person and can be characterized as: weakness in the lower extremities, cramps, pain, numbness or a combination of these symptoms
