Influence of ligating different sites of carotid arteries on face and nose blood flow in rabbits / 第二军医大学学报

ABSTRACT

Objective: To study the influence of ligating different sites of carotid arteries on face and nose blood flow in rabbits. Methods:Different levels of carotid arteries were ligated using laser Doppler flowmetry to observe the change of blood flow in face and nose regions before and after operation. Results: Blood flow of rabbit nose was more than that of the face region. Among the four operations of ligating different blood vessels to reduce blood flow of face and nose region, the most effective method was to ligate ipsilateral carotid artery and its branches on the same side. Conclusion: Ligation of some relating blood vessels, resulting in the establishment of collateral circulation, and the blood flow is quicker in the early stage. [
