The results of this important study show a high frequency, higher than expected, of catheter thrombosis in ICU patients, which raises the question of the clinical relevance of these events. The evidence that would support the weight of events diagnosed during systematic screening is drawn from prevention strategies in surgery, particularly in orthopedic surgery, where thromboembolic events are identifed through systematic ultrasound screening, as it was also done in this study. Conversely, it is possible to think that the severity of a catheter thrombosis could be different from distal thrombosis in orthopedic surgery, where the risk of migration is known, but not the risk of proximal extension and embolic migration.

这项重要研究的结果显示，ICU患者形成导管血栓的频率较高，高于预期，这提出了导管血栓临床重要性的问题。支持系统性筛查期间诊断事件权重的证据来自手术预防，尤其是骨科手术的血栓预防，通过系统性超声筛查识别骨科手术的血栓栓塞事件，与本研究方法相同。相反，可以认为导管血栓形成的严重度可能不同与骨科手术中的远端血栓，远端血栓的移位风险已知，但可以认为导管血栓与骨科近端血栓延长和栓塞性移位的风险一样，是未知的。
