OBJECTIVE
Deep-vein thrombosis is common but not easy to diagnose. It is generally considered that the diagnosis can be ruled out in subjects with a D-Dimer level lower than a reference threshold value. We report a case where this hypothesis was misleading.
METHOD
An 89-year-old man was hospitalized for a pain in his left lower leg, which had been persistent for 5 days.
RESULTS
The venous duplex ultrasound found two recent deep-vein thrombi in this leg while the D-Dimer level was lower than 220 UI/ml at admission.
CONCLUSION
This case illustrates the importance of prudent interpretation of the serum D-Dimer level.
目的
深静脉血栓形成很常见，但不易诊断。一般认为，D - 二聚体水平低于参考阈值的患者可排除诊断。我们报告一例该假设产生误导的病例。
方法
一名89岁男性因左下肢疼痛持续5天入院。
结果
静脉双重超声检查发现该下肢近期有两处深静脉血栓形成，而入院时D - 二聚体水平低于220 UI/ml。
结论
该病例说明了谨慎解读血清D - 二聚体水平的重要性。
