[The influence of nasal blood flow after ligating external carotid artery and its branches in rabbits].
OBJECTIVE
To study the influence of nasal blood flow after ligation of external carotid artery and its branches.


METHODS
We ligate different levels of external carotid artery and its branches, and use laser Doppler flowmetry to observe the change of blood flow in nose before and after operation.


RESULTS
Among the four types of operation ligating different blood vessels to reduce the blood flow of the operating side, the most effective way is to ligate ipsilateral carotid artery and its branches in the same side.


CONCLUSIONS
After ligation of relating blood vessels, the collateral circulation construct very soon, and the founding speed of that is quicker in the early stage.
