Four characteristics of vascular echo suggesting arterial thromboembolism: differentiation from aggravation of atherosclerotic peripheral artery disease

Background Arterial thromboembolism (ATE) leading to acute arterial occlusion can involve life-threatening complications, including limb loss and death, without prompt thrombectomy. Several ATEs are hard to differentiate from acute aggravation of atherosclerotic peripheral artery disease (PAD). We determined four characteristics of vascular echos suggesting ATE for the differentiation from PAD and validated their use.
