摘要
标准的止血检查[快速时间(QT)和活化部分凝血酶时间(APTT)]是非常常用的处方,但对于不擅长止血的医生来说,其解释往往很困难。在此,我们将回顾这些检查的诊断原则。只需对凝血级联有非常基本的了解,就能确定应进行哪些凝血因子检测并解释检测结果。多种凝血因子缺乏提示肝功能异常、弥散性血管内凝血(DIC)或维生素 K 缺乏。如果是单一因子缺乏,我们将回顾后天缺乏的不同原因,并简要讨论不同先天缺陷的特点,这些缺陷通常需要专门的治疗。狼疮抗凝物是导致 APTT 延长的一个常见且通常是良性的原因,需要引起注意,它与出血风险无关。掌握 QT 或 APTT 异常的诊断方法通常可以解决最常见的情况。
Orientation diagnostique devant une anomalie du TP ou du TCA
The standard hemostasis workup [quick time (QT), and activated partial thrombin time (APTT)] is very commonly prescribed but its interpretation is often difficult for practitioners who are not specialized in hemostasis. Here, we review the principles of the diagnostic approach to these tests. Only a very basic knowledge of the coagulation cascade is necessary to identify which clotting factor tests to prescribe and to interpret the results. Deficiency in several clotting factors suggests liver dysfunction, disseminated intravascular coagulation (DIC) or vitamin K deficiency. If a single factor is deficient, we review the different causes of acquired deficiencies and briefly discuss the characteristics of the different congenital defects, which generally require specialized management. Lupus anticoagulant is a common and generally benign cause of prolonged APTT to be aware of, which is not related to a hemorrhagic risk. A good knowledge of the diagnostic approach to abnormal QT or APTT generally allows the resolution of the most common situations.
期刊介绍:
Official journal of the SNFMI, La revue de medecine interne is indexed in the most prestigious databases. It is the most efficient French language journal available for internal medicine specialists who want to expand their knowledge and skills beyond their own discipline. It is also the main French language international medium for French research works. The journal publishes each month editorials, original articles, review articles, short communications, etc. These articles address the fundamental and innumerable facets of internal medicine, spanning all medical specialties. Manuscripts may be submitted in French or in English.
La revue de medecine interne also includes additional issues publishing the proceedings of the two annual French meetings of internal medicine (June and December), as well as thematic issues.
