Patients presenting to the emergency department with lower extremity symptoms suggestive of venous thromboembolic disease require a diagnostic evaluation. Although contrast venography was the diagnostic standard, this has largely been replaced by duplex ultrasound as the first-line imaging modality. This review presents a summary of the literature on the evolution and performance of B-mode point-of-care compression ultrasound as an alternative to duplex ultrasound evaluation. The 2-point compression and 2-region compression techniques are described. The limitations of point-of-care ultrasound of the lower extremity as a diagnostic modality for this disease entity, the role of a D-dimer assay in the emergency department evaluation and future directions for this diagnostic modality are discussed.
因下肢症状提示静脉血栓栓塞性疾病而到急诊科就诊的患者需要进行诊断评估。尽管静脉造影曾是诊断标准，但如今它在很大程度上已被双功超声取代，成为一线成像方式。本综述总结了关于B型即时护理压迫超声作为双功超声评估替代方法的发展及性能的文献。文中描述了两点压迫和两区域压迫技术。讨论了下肢即时护理超声作为该疾病实体诊断方式的局限性、D-二聚体检测在急诊科评估中的作用以及该诊断方式的未来发展方向。
