Carotid duplex ultrasound testing provides a safe and accurate method to detect and grade the severity of atherosclerotic internal carotid artery stenosis both before and following carotid intervention. Testing after surgical endarterectomy or stent angioplasty allows assessment of the technical success by excluding residual stenosis. The focus of duplex surveillance after carotid intervention is to identify recurrent stenosis, repair site occlusion, and progression of contralateral internal carotid artery disease. Patients who develop a neurologic event or a duplex-detected >75% diameter-reducing internal carotid artery stenosis with a peak systolic velocity >300 cm/s and end-diastolic velocity >125 cm/s should be further evaluated by angiographic imaging and should be considered for reintervention if an appropriate lesion is confirmed. Duplex surveillance allows the vascular surgeon to evaluate patency of the rendered intervention, its stenosis-free durability, and its effectiveness in stroke prevention.
颈动脉双功超声检查提供了一种安全且准确的方法，用于在颈动脉介入治疗前后检测和评估动脉粥样硬化性颈内动脉狭窄的严重程度。手术内膜切除术或支架血管成形术后的检查可通过排除残余狭窄来评估技术成功率。颈动脉介入治疗后双功超声监测的重点是识别复发性狭窄、修复部位闭塞以及对侧颈内动脉疾病的进展。发生神经系统事件或双功超声检测到颈内动脉直径缩小>75%，收缩期峰值速度>300 cm/s且舒张末期速度>125 cm/s的患者，应通过血管造影成像进行进一步评估，如确认有合适的病变，应考虑再次干预。双功超声监测可让血管外科医生评估所实施干预的通畅性、无狭窄耐久性及其预防中风的有效性。
