腘静脉的组成及其瓣膜的观测

The Formation of the Popliteal Vein and the Observation of Its Valves

对100侧成人尸体各23侧童尸下肢小腿深静脉的观察和测量,结果表明:腘静脉的支数以2支型最多(65.85%);腘静脉的组成分2个主型和10个亚型,以Ⅰ a 型最多(26.39%);腘静脉外径(成人86侧)1支型平均值为6.03mm、2支型大支为6.35mm,小腿诸深静脉外径均较细小。102侧腘静脉中平均每条腘静脉有2.26个瓣,一条腘静脉内有2个瓣者最多(53.92%);腘静脉第1段第1瓣位置平均在膝关节线以上12.06cm,胭静脉第2段第1瓣位置在膝关节线以下2.08cm。92侧小隐静脉的回流分3型,正常型最多见(占78.26%)。

The deep Veins were observed and measured on 100 lower extremities of Chinese Adult cadavers and 23child cadavers.The results show following:Two trunks of popliteal vein occur in 65.85%;The patterns of popliteal vein were divided into two main types and ten subtypes and type Ⅱa occurs most frequently(26.39%);it average calibres of the single and two popliteal vein(86 adult's)are 6.03 mm and 6.35 mm and the calibre of the deep vein is smaller;There are 2.26 valves every popliteal vein among 102 popliteal veins and a popliteal vein with two valves occurs in 53.92%;The first valve of the first section locates 12.06cm above the knee joint and the first valve of the second section locates 2.08cm under the knee joint;The reflux's patterns of short saphenous vein were divided into three types and the normal type occurs in 78.26%.
