A 10-year-old girl had bilateral, symmetrical swelling of the lower extremities, which had been present since the age of 1 year. Noninvasive vascular laboratory measurements of the ambulatory venous pressure, venous recovery time, and maximum venous outflow revealed profound bilateral lower extremity venous valvular incompetence. Duplex imaging of the veins of the lower extremities demonstrated no evidence of thrombosis, and no venous valves could be imaged. On phlebography, the patient was found to have no venous valves in the superficial and deep systems of the leg. We conclude that congenital absence of the venous valves of the lower extremities is almost certainly underdiagnosed and that the vascular laboratory can accurately and easily differentiate between lymphedema and venous valvular imcompetence. Such differentiation may have therapeutic implications.
一名10岁女孩自1岁起双下肢出现双侧对称性肿胀。对其动态静脉压、静脉恢复时间和最大静脉流出量进行的非侵入性血管实验室测量显示，双侧下肢存在严重的静脉瓣膜功能不全。下肢静脉的双功超声成像未发现血栓形成迹象，也未显示静脉瓣膜。在静脉造影检查中，发现该患者腿部浅静脉和深静脉系统均无静脉瓣膜。我们得出结论，下肢静脉瓣膜先天性缺失几乎肯定未得到充分诊断，并且血管实验室能够准确且轻松地区分淋巴水肿和静脉瓣膜功能不全。这种区分可能具有治疗意义。
