肘区动脉网的巨微解剖

THE MACRO-MICROANATOMY OF THE ELBOW ARTERIAL NETWORK

手术显微镜下,观察了30例成人上肢肘区动脉网标本。它的组成可来自10条动脉,但以邻近动脉为主,符合动脉就近分布规律。根据动脉支吻合的密集程度,可将肘区动脉网分为五部分,后、外侧网吻合密度大。动脉网是肘关节的主要供血来源,是肘区侧副循环的主要形态基础。

The elbow arterial networks of 30 adult upper limb specimens were observed and studied b> the operating microscope. The constitution of the elbow arterial network originates from 10 arteries, but the arteries near the joint arc the main source.which conforms to the rule of the near distribution of arteries. Based upon the density of the arterial anastomosis, the elbow arterial network might be divided into five portions, in which the dorsalate danlral networks are the densest. The networks are the main blood source of the elboxy wjoint and the main construction of the collateral circulation in the elbow.
