深静脉血栓形成后综合征（PTS）病理变化复杂，如何选择合适的治疗方法一直是血管外科的复杂难题。了解其病理学变化和血流动力学特征，进行特殊检查，如深静脉顺行造影和多普勒超声检测，有助于诊断和制定个体化的治疗方案。缓解症状、提高生活质量是治疗该病的原则，尤其要重视通过手术或介入治疗早期解除髂静脉回流障碍。预防PTS发生比缓解PTS症状的意义更为重要。腔内导管溶栓术（CDT）能够有效减少血栓形成后PTS的发生、发展。

Abstract   As the complicated pathological changes of PTS, how to choose appropriate treatment has always been one of the tough issues in vascular surgery. It is very important to understand pathology, hemodynamic characteristics and special examinations such as antegrade venography and Doppler which will help to custom-design the treatments. The therapeutic aims include symptoms relief and life quality improvement. Attention should be paid to solve iliac venous obstruction by surgery or intervention. PTS preventing is more important than symptom relieving. Catheter-directed thrombolysis has incidence reducing effect of PTS after DVT.
