下肢深静脉倒流性功能不全和瓣膜功能定位检测

作者倡用一种新的下肢深静脉造影术,即经皮腘静脉插管造影方法。在腘窝部穿刺腘静脉,向近侧插入导管作造影检查,非但可以清晰地显示髂-股-腘静脉,更能逐一测试这段静脉中每一对瓣的功能,弥补了顺行和逆行造影术的不足。根据本研究资料,对发病机理、诊断及治疗方法等提出了新的观点和指导原则,并已在临床得到验证。

Studies on Incompetence of Deep Veins due to Blood Reflux and Percutaneous Transpopliteal Venography in Evaluating Valvular Function

The authors advocate percutaneous transpopliteal venography as a new and reliable method in evaluating the function of the valves in deep veins, especially those in the femoro-popliteal vein of the lower extremity. At the popliteal fossa, the poplitcal vein is punctured and a catheter is inserted proximally for venographic study of the valves. By this method, not only the ilio-femoro-popliteal vein is clearly visualized, the function of the valves in this venous segment can also be accurately tested one by one, remedying the shortcomings of ascending and descending venography. It was found, through this venography, that eveu if the highest valve of the superficial femoral vein is competent, the distal valves in the femoral and popliteal veins may become incompetent, also resulting in primary valvular incompetence of the deep veins of the lower extremity.
