Acute limb ischemia is both a limb-threatening and life-threatening disease process. Nontraumatic acute peripheral arterial occlusion is most commonly caused by a thrombosis or an embolism.
There is limited evidence on the use of bedside ultrasound for the detection of acute limb ischemia, but duplex ultrasonography is standard in the diagnosis and operative planning in chronic limb ischemia. Emergency physicians may use bedside ultrasound in the evaluation of patients with symptoms and signs suggestive of this disease entity.
A 64-year-old man with a past medical history of hypertension and an ischemic stroke presented to the Emergency Department with <2 h of severe upper left leg pain that radiated down to his foot. A bedside ultrasound of the left lower extremity was emergently performed. On B-mode ultrasound evaluation, echogenic material was visualized in the left common femoral artery, the artery was noncompressible, and there was an absence of Doppler flow signal. He was then directly taken to the operating room for an emergent limb-saving procedure.
A focused examination of the aorta, iliac vessels, and femoral artery bifurcation with bedside ultrasonography may help to localize peripheral arterial occlusions and can assist the emergency physician in seeking timely surgical consultation and management.
急性肢体缺血是一种既威胁肢体又威胁生命的疾病过程。非创伤性急性外周动脉闭塞最常见的原因是血栓形成或栓塞。
关于床旁超声用于检测急性肢体缺血的证据有限,但双功超声检查是慢性肢体缺血诊断和手术规划的标准方法。急诊医生可能会在评估有提示该疾病实体症状和体征的患者时使用床旁超声。
一名64岁男性,有高血压和缺血性中风病史,因左上腿严重疼痛<2小时并放射至足部就诊于急诊科。紧急进行了左下肢床旁超声检查。在B型超声评估中,在左股总动脉中可见回声物质,该动脉不可压缩,且无多普勒血流信号。随后他被直接送往手术室进行紧急保肢手术。
使用床旁超声对主动脉、髂血管和股动脉分叉进行重点检查可能有助于定位外周动脉闭塞,并可协助急诊医生及时寻求手术会诊和治疗。
