在24侧(男女各12)标本就腘静脉的形态和相关瓣膜进行了观察,结果如下:1.按腘静脉的形成可分为三型:①常见型.指胫前静脉与胫后静脉在腘肌下缘形成腘静脉,见10侧(左6右4),占41.6±10.27%.②高位型.即胫前静脉与胫后静脉在腘肌下缘以上,浅面或收肌管裂孔处才形成腘静脉者属之,见7侧(左5右2)占29.16±9.48%.③低位型.指胫前、后静脉在腘肌下缘以下形成腘静脉者,见7侧9左2右5)占29.1±9.48%. In the 24 sides (12 men and women) specimens of the vein morphology and related valves were observed, the results are as follows: 1. According to the formation of veins can be divided into three types: ① common type refers to the anterior tibial vein and posterior tibial vein in The lower edge of the hypothalamic muscle formed 腘 vein, see 10 side (left 6 right 4), accounting for 41.6 ± 10.27%. ② high type, that is, anterior tibial vein and posterior tibial vein above the lower edge of the hypothalamic muscle, See the 7 side (left 5 right 2) accounted for 29.16 ± 9.48% .③The low type refers to the anterior tibial and posterior venous in the lower edge of the hypothalamic plexus to form the vein, see 7 side 9 left 2 right 5) accounted for 29.1 ± 9.48%.
