Method for building animal model of forming thrombus of deep vein in traumatic limbs and trunk of rat

Abstract

A method for creating the animal model of traumatic deep venous thrombosis in limbs features that the intramedullary nail driver is reformed to become a quantitative beater and said beater is used to beat the near ends of lower limbs of rat to obtain said animal model.

Description

technical field [0001] The invention relates to the technical field of medical models, and is a method for establishing an animal model of traumatic limb deep vein thrombosis with orthopedic clinical characteristics, which can be used to study the occurrence, development and outcome of traumatic limb deep vein thrombosis and pulmonary thromboembolism, and explore more effectively The method of prevention, diagnosis and treatment provides an animal model platform. Background technique [0002] Thrombosis is a kind of disease that seriously endangers human health and life. It is found in patients in many clinical departments. Its morbidity, disability and mortality are very high, and it is extremely harmful. In western countries, the incidence rate of venous thromboembolism (VTE) is as high as 0.1%, and half of them are deep venous thrombosis (DVT). In the United States, there are about 650,000 hospitalizations and 50,000-200,000 deaths each year due to DVT and pulmonary thro...

Problems solved by technology

[0006] Although the above modeling methods have their own characteristics, they are mainly used to study changes in blood coagulation and fibrinolytic systems, as well as related drug screening and curative effect evaluation, which are not consistent with the actual natural course of clinical DVT in orthopedics: (1) Absolute clinical DVT in orthopedics Most of them are subacute or chronic, and the thrombus formed by the above methods are all acute; (2), orthopedic clinical DVT hardly directly damages deep veins, and the above methods all directly damage blood vessels

(3) Most of the orthopedic clinical DVT occurs in patients with immobilized limbs after trauma or surgery and long-term bed rest. DVT occurs despite anticoagulants
