摘要
颈外动脉结扎术是预防和治疗头面部严重出血的重要方法之一。本文应用２５只新西兰大白兔，分别结扎右颈外动脉；双侧颈外动脉；右颈外动脉＋右侧分支血管及右侧颈外动脉分支血管。分别于术前、术后即刻、术后１、２、４、５、２４小时测量唇部、面颊部、下眼睑的血流值，结果显示术后１、２、３小时血流变化有差异，４。
Abstract It is
one of the most important methods to prevent and treat severe bleeding of maxillary and facial
region to ligate external carotid artery (ECA).Many scholars point out that this method is
effective in controlling bleeding in some head and neck operations and also effective to treat
epistaxis.But others thought this method can't get the purpose because abundant collateral
circulation will be founded after ligation of ECA.Wether to ligate ECA and its branches or
embolize have not concluded.We ligate different level of ECA and its branches,using laser
Doppler flowmetry to observe the change of blood flow in maxillary and facial region.The
purpose of this article is try to confirm which ligative method is most effective to decrease
bleeding,when the collateral circulation is founded and which is the main collateral circulation.
