摘要
目的 :研究下肢深静脉瓣膜关闭功能不全的分型与影像学诊断。材料与方法 :2 16条肢体均行下肢深静脉顺行造影 ,其中 15 2条肢体行经皮月国静脉插管造影 ,并对 14条单纯性大隐静脉曲张 (正常瓣膜 )肢体进行血液动力学观察。结果 :2 0 2条肢体诊断为下肢静脉关闭下全 ,14条肢体诊断为单纯型大隐静脉曲张 ,其中 ,Ⅰ型 :深静脉瓣膜脱垂致瓣膜关闭不全 2 6例 ;Ⅱ型 :深浅静脉扩张致瓣膜相对关闭不全 3 3例 ;Ⅲ型 :瓣膜脱垂加股静脉扩张 3 6例 ;Ⅳ型 :先天性下肢深静瓣膜发育不全症 4例 ;Ⅴ型 :深静脉血栓形成后完全再通瓣膜遭破坏 3 9例。 14条单纯性大隐静脉 ,瓣膜完全正常 ,屏气时正常肢体股静脉第一对瓣膜、月国静脉瓣膜同时关闭 ,足背伸屈运动时月国静脉瓣膜开放程度显著大于股静脉第一对瓣膜 (P <0 0 1)。结论 :下肢深静脉瓣膜关闭功能不全能全面反映疾病的病理本质 。
Purpose:To assess the typing and imaging diagnosis og lower limbsdeep vein valve closure insufficiency.Materails and Methods:216 stick limbs and trunk performed lower limb deep vein radiography,152 sticks lower limb intubate vena poplitea radiography and 14 sticks limbs and trunks of simple form varicosis of great saphenous vein in march hematodynamics.Results:202 sticks limnbs and trund are diagnosised lower limb deep vein closure insufficiency.Ⅰ:26 cases deep vein valve prolapse;Ⅱ:33 cases superficial femoral vein dilation lead to valve incompetence;Ⅲ: 36 cases valve prolapse consolidation superficial femoral vein dilatation;Ⅳ:4 cases valve aplasia congenitalis.Ⅴ:39 cases thrombophoebitis.14 sticks valve normal breath holding valve of simple form varicosis of great saphenous vein and metatarsal poplitea simultaneous closure,instep outreach and atcuatiion,valve of vena poplitea open more than valve of simple form varicosis of great saphenous vein (P<0 01).Conclusion:Lower limbs deep vein valve closue insufficiency reflect pathologyic process of disease.
