作者在作冠状动脉旁路术取病人下肢静脉时注意到,下肢静脉的解剖与以往经典描述有一些不符之处。为此,从1980年6月起在作该术时,接连研究了59例95条下肢大隐静脉的行径、分支、瓣膜位置和穿通支的解剖及其与静脉病变的关系。结果表明,大隐静脉通过侧枝和小隐静脉交通;通过穿通支直接或间接地和深静脉系统交通;通过分支和胫前静脉、胫后静脉交通;和小腿前静脉、后弓静脉相通。小腿静脉由三层组成。浅静脉为第一层,走行在皮肤和浅筋膜层之间,壁菲薄、无肌肉组织、支撑薄弱,容易扩张和扭曲,它们间隔地穿过浅筋膜,与大隐静脉相通;大隐静脉为第二层,行走在浅筋膜下,壁的肌层较
When the author took a coronary artery bypass surgery to take the patient’s lower extremity veins noted that the veins of the lower extremity anatomy and past classic description of some discrepancies. To this end, from June 1980 at the time of surgery, a series of 59 cases of saphenous vein of 95 lower extremity sagittal, branch, valve position and the anatomy of the perforating branch and its relationship with the vein. The results show that the saphenous vein through the collateral and small saphenous vein traffic; through the perforation branch directly or indirectly and the deep venous system traffic; through the branch and the anterior tibial vein, posterior tibial vein traffic; and anteroposterior vein, posterior arch vein communication. Calf vein consists of three layers. Superficial vein as the first layer, walking in the skin and superficial fascia between the thin wall, no muscle tissue, weak support, easy to expand and distort, they interpenetrated through the superficial fascia, communicating with the great saphenous vein; Great hidden Veins for the second layer, walking in the superficial fascia, the muscular wall more
