In a retrospective study carried out over a 5-year period, 88 patients with acute limb ischaemia underwent echocardiography. Of this group, 74 were thought to have an embolic cause of ischaemia on either operative or arteriographic findings. Two-dimensional echocardiography detected a cardiac source in 30 patients (sensitivity 41%, specificity 100%). Clinical examination on admission correctly indicated an embolic source in 36 patients (sensitivity 49%, specificity 36%). The combination of echocardiography and clinical examination detected an embolic source in 60 of 74 (81%) patients. In this study echocardiography complemented clinical examination in the diagnosis of a cardiac source of acute limb ischaemia.
在一项为期5年的回顾性研究中，88例急性肢体缺血患者接受了超声心动图检查。在该组患者中，根据手术或血管造影结果，74例被认为存在缺血的栓塞原因。二维超声心动图在30例患者中检测到心脏来源（敏感性41%，特异性100%）。入院时的临床检查在36例患者中正确指出了栓塞来源（敏感性49%，特异性36%）。超声心动图和临床检查相结合，在74例患者中的60例（81%）检测到了栓塞来源。在本研究中，超声心动图在急性肢体缺血心脏来源的诊断中补充了临床检查。
