{Reference Type}: Journal Article {Title}: Surgery or Endovascular Therapy for Chronic Limb-Threatening Ischemia. {Author}: Cheng TW;Farber A; {Journal}: Adv Surg {Volume}: 58 {Issue}: 1 {Year}: 2024 Sep 暂无{DOI}: 10.1016/j.yasu.2024.04.008 {Abstract}: Chronic limb-threatening ischemia is defined as ischemic rest pain or tissue loss (eg, ulceration/gangrene) that has been present for greater than 2 weeks. Workup includes a careful history, physical examination focused on evaluation of pulses and wounds, lower extremity noninvasive vascular studies (eg, ankle-brachial indices, toe pressures), saphenous vein mapping, and imaging of the lower extremity arterial anatomy (eg, computed tomography, magnetic resonance, or subtraction angiography) if a revascularization intervention is planned.
