[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 of the channel area of legs.


METHODS
The integument tissue of the lower limbs in the 12 cadavers were dissected with macro-and micro-dissection, 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-yin 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.


CONCLUSIONS
An obvious nutrient vascular chain is formed in the integument tissue along the channel area of legs except the Stomach Meridian.
