Many guidelines suggest incorporating clinical assessment, imaging, and D-dimer testing into diagnostic algorithms in patients with suspected deep venous thrombosis (DVT) and pulmonary embolism (PE). This special article reviews the evidence supporting the use of algorithms and their individual components for diagnosis of upper- and lower-extremity DVT and PE in adults, including pregnant women. The authors identified evidence through several electronic database searches to April 2017, evaluated the robustness of selected evidence, assessed whether diagnostic approaches that do not use algorithms are acceptable, and identified knowledge gaps that require further research.

许多指南建议将可疑深静脉血栓形成（DVT）和肺栓塞（PE）的患者的临床评估，影像学和D-二聚体测试纳入诊断算法。这篇特别文章回顾了支持使用算法及其各个组件来诊断包括孕妇在内的成年人的上下肢DVT和PE的证据。作者通过截至2017年4月的几次电子数据库搜索确定了证据，评估了选定证据的稳健性，评估了不使用算法的诊断方法是否可以接受，并确定了需要进一步研究的知识差距。
