摘要
报道57侧下肢走动静脉压(AVP)测量结果。发现静止静脉压(P_0)没有确定的临床诊断价值;运动后最低静脉压(P_∞),主要反映小腿肌肉泵功能,与临床症状关系密切,随着P_∞值的增高临床症状发生率也增高;运动终止后压力恢复时间(RT_(90)),主要由深浅静脉倒流程度决定。于踝部结扎止血带可以提高AVP测量的诊断率。在影响下肢静脉血流动力学的多种因素中,小腿肌肉收缩的泵功能是静脉回流的主要动力。AVP测量对下肢静脉病的诊断、预后和静脉重建手术的设计均有一定价值。
This paper reports the results of ambulatory venous pressure (AVP) measurements in 57 lower limbs. We found that the resting venous pressure (Po) had no diagnostic value, whereas the minimum ambulatory venous pressure (P_∞), mainly reflecting the function of calf muscle pump, was closely related to clinical symptoms. With increasing P_∞, there was increase the incidence of clinical symptoms. The venous pressure recovery time after physical exercise (90% recovery time RT90) was determined by reflex of deep and superficial veins. It may increase the diagnostic incidence of AVP measurement by applying an ankle cuff. In many factors affecting the venous hemodynamics of the lower limb, the pumping function of the calf muscle contraction is the principal power responsable for venous return. AVP measurement is significant not only in diagnosis and prognosis, but also in the designs of venous reconstructive procedures for venous diseases of the low limbs.
