Arteriosclerosing occlusive disease is the most common peripheral arterial disease in clinical practice. Traditional Chinese medicine has unique advantages in treating arteriosclerosing occlusive disease. The theory of blood-vessel syndrome differentiation takes vessels as the main body and basic framework

and blood as the material basis. It holds that abnormal shape and dysfunction of vessels are two key factors in the pathogenesis of peripheral vascular diseases.The physiological characteristics of vessels are discussed by taking vessels as the physique and dredging for use

and the function of vessels is discussed by obstructing blood to communicate with

ying wei

and carrying Qi and blood to carry body fluids. Physiologically

blood favors warmth and dislikes cold and it serves "to help and nourish the physique and spirit" . The disease location of arteriosclerotic occlusive disease is in blood

with the blood stasis of limbs as its core pathogenesis. Based on the theory of blood-vessel syndrome differentiation

arteriosclerotic occlusive disease is divided into the patterns of yin and cold of the collaterals

blood stasis of collaterals

blood stasis with heat in the collaterals

and blood stasis and toxin accumulation in the collaterals. Combined with clinical cases

this paper introduces the treatment of arteriosclerotic occlusive disease based on syndrome differentiation.
