Abstract:

BACKGROUND: Construction of animal models of vertebral artery type of cervical spondylosis and evaluation have become a new issue of concern.
OBJECTIVE: To describe the research progress of animal models of vertebral artery type of cervical spondylosis at home and abroad, and to evaluate the advantages and disadvantages of each method.
METHODS: The keywords were “cervical vertigo, basal-vertebral ischemia, cervical spondylosis of vertebral artery type, animal, model” in Chinese and English, respectively. CNKI, WanFang, VIP, PubMed, Cochrane Library, and Embase databases were retrieved for the articles published from 1998 to 2018. Chinese and English articles on animal modeling of vertebral artery type of cervical spondylosis were selected according to the inclusion and exclusion diagnosis criteria of vertebral artery type of cervical spondylosis.
RESULTS AND CONCLUSION: Through induction and analysis, modeling methods include hardener injection, bone graft compression, dynamic imbalance, blood stasis blocking collaturation, vertebral artery ligation and mixed modeling method. Of them, hardener injection method is most commonly used. Bone graft compression method is the most similar pathogenesis to the human body. However, the disadvantage is that the modeling is difficult and the size of the bone block is various. So the bone is not in the right position. Dynamic imbalance method can cause cervical spine imbalanced by resecting the unilateral muscle and bone. This method has high operability, but has long modeling period. Although ligating or clipping the unilateral vertebral artery is easy to operate, the pathogenesis of vertebral artery type of cervical spondylosis is not just vertebral artery stenosis, which ignores the influence of humoral factors, sympathetic nerves and vertebral nerves on the blood flow velocity and lumen size of vertebral artery. Each method has advantages and disadvantages. The evaluation criteria, time and success rate are different.
