结扎颈动脉不同部位对兔面部和鼻部血流量的影响

目的：探讨结扎颈动脉不同部位后对兔面部和鼻部血流的影响。方法：结扎兔颈动脉的不同部位，利用激光多普勒血流计动态观察结扎手术前后兔面部和鼻部血流的变化。结果：（１）兔鼻部的血流量较面部丰富。（２）４种不同部位的颈动脉结扎手术后２４ｈ内兔鼻面部血流量的变化，以结扎单侧颈外动脉及其分支组最低，单侧颈外动脉结扎组和双侧颈外动脉结扎组次之，单侧颈外动脉加同侧颈总动脉结扎组最高。（３）结扎术后不同时间兔鼻面部

Influence of ligating different sites of carotid arteries on face and nose blood flow in rabbits

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. [
