【摘要】 目的探讨Labbe’s静脉的形态及其与横窦的关系,指导临床手术。方法对20具经血管内灌注染料的成人尸头,行颞下-乙状窦后-枕下联合开颅术,在手术显微镜下观察两侧40例Labbe’s静脉的形态、到达横窦的位置、距离与夹角,横窦断面与Labbe’s静脉点的关系。结果Labbe’s静脉表现为单干型,双干型,烛台型,静脉窦或多干型。65%进入到横窦的上壁,25%进入到外侧壁,10%进入到内侧壁。与横窦的夹角,50%为锐角,30%为直角,20%为钝角。与横窦-乙状窦交汇点的平均距离为左侧2.6±1.3cm,右侧2.2±1.1cm。结论Labbe’s静脉可以表现为多种形态,了解不同形态对指导临床手术有重要意义;Labbe’s静脉进入到横窦外侧壁、与横窦呈直角、单干型或烛台型较易损伤。更多还原

【Abstract】 Objective To explore shapes of Labbe’s vein and its relation to transverse sinus in order to correctly identify and avoid to damages it during operations.Methods Subtemporal-postsig moidal-suboccipital approach were applied in20adult cadaver heads with perfusion of vassels under operative microscope.Observation items involved shapes,position,distance and angles to transverse sinus of Labbe’s vein and its relations to entry point to transverse sinus.Result The main types on Labbe’s vein were single,doubles,candlestick,venous sinus or multiples.Entry point came from superior wall of transverse sinus was65%,lateral outside wall25%,lateral inside wall10%.The angles to transverse sinus was50%in acute,30%in right,20%in obtuse.The distance from Labbe’s vein to connect point between sigmoid sinus and transverse sinus was2.6±1.3cm in left side2.2±1.1cm in right side.Conclusions Labbe’s vein show variable shapes,knowing its different conditions have important significant to instruct operative procedures.The following situations were easy to injure:Labbe’s vein entering lateral wall,right angles,single or candlesticke shapes.[更多还原
