本文研究了57侧肘关节动脉的血液供应。动脉起点以前、后支起始位置的变异较常见,且以尺返动脉居多。尺侧上副动脉和肱深动脉的共干是仅有的一种形式。个别动脉的本干、前支和后支可以为2支。明显的肘前和肘后两网由纯关节支和肌关节支组成,但两者在形态和功能上不如膝关节明确和重要。网的组成有主次来源和层次关系。各局部动脉网亦不发达,存有相对的乏血管区。肘前髁上和滑车上水平血管吻合丰富,围绕肘后二沟一窝呈“H”形的动脉网为其特征,连接左右纵干的横干所在髁水平,亦是血液供应最丰富的部位。可将动脉分成3组,两侧动脉口径和起点高度的差异不明显,但动脉口径之间和起点高度之间仍有规律可循。各动脉前、后支在口径和分布范围上的互补作用比较明显。
This article studies the blood supply to 57 elbow arteries. Before the beginning of the artery, the posterior branch of the variation of the starting position is more common, and the ulnar return artery mostly. The ulnar side of the common artery and brachial artery co-dry is the only form. The individual arteries of the stem, anterior branch and posterior branch can be 2. Obvious elbow before and after the two nets by pure articular and muscular articular branch, but both in shape and function as knee clear and important. The composition of the network has primary and secondary sources and levels. The local arterial network is also underdeveloped, there are relative lack of vascular area. Anterolateral elbow and the pulley on the level of vascular anastomosis rich, around the elbow a ditch was a “H” shaped arterial network as the characteristics of the left and right vertical stem horizontal axis where the condyle is also the most abundant parts of the blood supply . Arteries can be divided into three groups, both sides of the arterial caliber and starting height difference is not obvious, but there is still a law between arterial caliber and starting height. The anterior and posterior branch of each artery in the caliber and distribution of the complementary role is obvious.
