小腿经络区体被组织的血管形态学研究

目的：观察小腿经络区的体被组织内血管的分布。方法：采用巨微解剖、全身动脉放射显影及图像分析技术，解剖12只下肢的体被组织，观察分析小腿经络沿线的体被组织内血管来源、分支和吻合情况。结果：足三阴经、胆经、膀胱经线区的小腿体被组织血管密度明显高于其他部位，在动脉显影X绒图像上分别形成一条明显的营养血管链；胃经沿线血管密度未见增高，也未见明显的营养血管链。结论：除胃经外，小腿经络区体被组织内均形成一条明显的皮神经营养血管链。

Study on vascular morphology of integument tissues of the channel area in the leg

Objective To observe the distribution of the blood vessels in the integument tissue ot the channel area of legs. Methods The integument tissue of the lower limbs in the 12 cadavers were dissected with macro-and microdissection, radiographical technique of systemic artery and technique of image pattern analysis to observe and analyze the origins, branches and anastomoses in the integument tissues along the channels of legs. Results The distributional density of the blood vessels in the integument tissues of legs along the channel area of the three-y/n meridians of the foot, the Gallbladder Meridian, and the Urinary Bladder Meridian was higher than that in the other parts. They formed an obvious nutrient vascular chain on the arteriogram. The distributional density in the channel area of the Stomach Meridian was not obviously increased and the obvious nutrient vascular chain could not be seen. Conclusion An obvious nutrient vascular chain is formed in the integument tissue along the channel area of legs except the Stomach Meridian.
