摘要
在专供研究用的21具(42侧)成人足标本上,解剖观测了足背浅静脉及其瓣膜,发现大、小隐静脉足背段瓣膜数分别为2.8个和1.4个;在第一～四跖背静脉汇入口处瓣膜出现率分别为70.0%,53.3%,85.3%,77.8%,在共干型的跖背静脉内瓣膜出现率达100%;在直径小于2mm的跖背静脉也观测到瓣膜。本文认为足背静脉(弓)作为移植体(静脉动脉化)来修复掌浅弓缺损可以减少临床修复掌浅弓手术的复杂性。但应充分重视足背静脉(弓)内及跖背静脉汇入口处的静脉瓣。
In 21 adult cadavers(42 sides), the length, external diameter of great saphenous and small saphenous vein segment of the dorsal veins of foot were observed and measured. Besides, the number, position, distribution, figure of the venous valve in the great and small saphenous vein segment, especially in the dorsal metatarsal veins were observed and measured. The clinical application and significance of the dorsal veins arch of foot and the venous valves were discussed.
