Some recent publications have emphasized the risk (up to 25%) of deep venous thrombosis (DVT) coexisting with a clinical evidence of superficial venous thrombosis (SVT). However, most papers on this topic are old and do not consider the use of the duplex scanning.
To determine what the spontaneous risk is of venous thrombosis and emboli in varicose patients, in the superficial veins, and in the deep veins; what the risk is of extension or coexistence between superficial and deep thrombosis; and whether the treatments of varicose disease are responsible for thrombosis?
Review of the literature.
The frequency of venous thrombosis appears to be increased in patients with varicose disease.
In all cases of clinical SVT a duplex scan examination of both deep and superficial veins is necessary in order to provide a complete diagnosis. The treatment of SVTs depends on the situation and the size of the thrombi. In case of associated DVT, the most important treatment is of the DVT. The interest of heparin or low molecular weight heparin (therapeutic doses) is proved for patients with coexisting DVT, and thought so for ascending SVT. Interest and doses have not been stated in other cases. SVT must be considered as a risk factor of DVT and treated from this point of view. Biological analysis and a complete check-up are mandatory in cases of varicose thrombosis in young patients and in cases of recurrence.
近期一些出版物强调了深静脉血栓形成（DVT）与浅静脉血栓形成（SVT）临床证据并存的风险（高达25%）。然而，关于该主题的大多数论文较为陈旧，未考虑使用双功扫描。
确定静脉曲张患者、浅静脉和深静脉中静脉血栓形成和栓子的自发风险是什么；浅静脉和深静脉血栓形成之间扩展或并存的风险是什么；以及静脉曲张疾病的治疗是否会导致血栓形成？
文献综述。
静脉曲张疾病患者静脉血栓形成的频率似乎有所增加。
在所有临床SVT病例中，有必要对深静脉和浅静脉进行双功扫描检查以做出完整诊断。SVT的治疗取决于血栓的情况和大小。若伴有DVT，最重要的治疗是针对DVT。肝素或低分子肝素（治疗剂量）对并存DVT的患者已被证实有效，对上行性SVT也被认为有效。在其他情况下，其有效性和剂量尚未明确。必须将SVT视为DVT的一个风险因素并从这一角度进行治疗。对于年轻患者的静脉曲张性血栓形成病例和复发病例，进行生物学分析和全面检查是必不可少的。
