The blood vessel wall is almost always nourished by two ways; from the blood stream itself and through the outer part of the wall by vasa vasorum.
The aim of this study was to demonstrate that this kind of nutrition is also available for the venous wall and to define the distribution pattern in superficial venous walls.
50 long saphenous veins and 20 short saphenous veins latex or barium injections, dissections with magnifying glasses and microradiographies. Topographical evaluation of the origin of vasa vasorum.
The results showed that vasa vasorum originated from perforating arteries coming from several levels and getting a lot of anastomosis. We showed that the main sources for the long saphenous vein are the external pudendal artery and descending artery of the knee and for the short saphenous vein, the short saphenous vein artery. In thrombosis and varicose veins, the vasa were strongly altered.
This study outlines the fact that superficial veins are supplied by arterial and venous vasa vasorum, and the role of vasa vasorum must be considered when questioning the pathogenesis of varicose and post thrombotic disease.
血管壁几乎总是通过两种方式获得营养;一是来自血流本身,二是通过血管滋养管从血管壁外部获得营养。
本研究的目的是证明这种营养方式也适用于静脉壁,并确定其在浅表静脉壁中的分布模式。
50条大隐静脉和20条小隐静脉,进行乳胶或钡剂注射、放大镜下解剖及微血管造影。对血管滋养管的起源进行局部评估。
结果显示,血管滋养管起源于来自多个层面的穿支动脉,且有大量吻合。我们发现,大隐静脉的主要来源是阴部外动脉和膝降动脉,小隐静脉的主要来源是小隐静脉动脉。在血栓形成和静脉曲张时,血管滋养管会发生明显改变。
本研究概述了浅表静脉由动脉和静脉血管滋养管供血这一事实,在探讨静脉曲张和血栓形成后疾病的发病机制时,必须考虑血管滋养管的作用。
