Deep Venous Insufficiency Of The Cause And Pathogenesis, Syndrome Differentiation

This study includes three parts:(1)literature summarization; (2)the theory on research of Deep Venous Valve Insufficiency of the lower limbs(DVI) was presented by the director-Prof. Chen Shu-chang;(3)the clinical research of DVI.In the first part, the author sums up the study progress on the treatment of DVI by the TCM. and the west medicine in the last 20 years.In the second part, the author sums up the study research of the director on DVI.In the last part, we adopt the uniform questionnaire to analyse the incidence, itiology and symptoms of the DVI.The 225 related cases of DVI were studied. We carried on the statistic methods and got the conclusion:(1)Obviously the incidence on the left lower limbs is more serious than that on the right lower limbs of DVI, because of the special feature in anatomy. (2)The varicose veins is not an absolutely necessary symbol of DVI,but only a common symbol. (3)The hard physical labour, standing for a long time or sedentariness everyday for many years, DVT and coldness,wounded or operated, family history are all closely related to DVI.We should pay more attention to the sedentary.The standard of grading for the symptoms and functions of the DVI patient were made in this thesis. It can be a basis for evaluating the curative effect. At last, we divided the 225 related cases into 3 types: the type of dampness blockage in the Mai-Luo(vessels and collateral channels), the type of dampness blockage and blood stasis in the Mai-Luo, and the type of damp toxins and stagnant heat in the Mai-Luo. We also made the general rules of treatment for each types,and discussed the relationship between the TCM. types of DVI and the results of the CDUS. All these will be a base for the next researching step.
