第1-4对肋间静脉的应用解剖

APPLIED ANATOMY OF THE FIRST TO THE FORTH INTERCOSTAL VEIN

在32具成人尸体上解剖观察了第14对肋间静脉间的组合型式、交通支、上、下端的汇入处及瓣膜发现第一肋间静脉经肋骨小头下向上可汇入椎静脉、头臂静脉、锁骨下静脉,其中以椎静脉为主(右侧40.63%左侧37.5%),汇入处外径右侧2.03±0.76mm,左侧2.13±0.91mm。第1-4对肋间静脉间的组合型式也相当复杂。右侧以第二与第三肋间静脉共干江入夺静脉弓较多,占28.13%,汇入处外径4.36±2.12mm。左侧以第二,第三和第四肋间静脉共干汇入奇静脉或副半奇静脉较多,占37.5%,汇入处外径2.56±1.71mm。同侧第1-4肋间静脉之间的纵行交通支左侧有19支(占59.4%),右侧有10支(占31.3%),主要是第一与第二肋间静脉之间的交通支。静脉内瓣膜较少(右侧19处,左侧11处)。

In 32 adult cadavers, the constitutional patterns, the veins droinning upward and downward and it's external diameter, transverse and longitudinal anastomotic brancnes, valves of the first to the forth intercostal vein were dissedted and studied. In the end the clinical application and significance in the diagnosis of these veins were also discussed.
