摘　　要：目的探讨Labbe静脉的形态、走行及注入横窦的方式,评估术中预离断Labbe静脉后重建的可行性。方法对10具(20侧)经福尔马林溶液固定的不同性别的成人头颅湿性标本进行血管灌注染色,然后行颞下-乙状窦后-枕下联合开颅,对Labbe静脉进行显微解剖测量。结果Labbe静脉可分为单支型、双支型、多支型和烛台型。其中单支型和双支型占70%左右,其汇入横窦的方式可分为前方汇入型、后方汇入型、天幕型和硬膜型;在其管径的测量中,直径2.0～3.0mm的占30%,3.1～4.0mm的占50%,4.1～5.0mm者占15%,>5.0mm者仅占5%。结论对于单支型和双支型者,直径在3mm以上的,可以通过术中预离断后再行重建,以利于手术操作和减少术后并发症的发生。Objective To explore the shapes and course of Labbe vein and the patterns of it infusing into the transverse sinus, in order to evaluate the possibility of re-construction after mutilation. Methods Suboccipital approach was applied and the diameter of Labbe veins was microanatomy measured in 10 adult cadaver heads after vascular perfusion. Results The main types of Labbe vein were single, doubles,candlestick and venous sinus or multiples. The first and the second types account about 70 %. The patterns of Labbe vein infusing into the transverse sinus were infusion in front or behind,infusion crossing the tentorium of cerebellum or the duramater; the diameter between 2.0 mm tO 3.0 mm of Labbe vein were 30% ,between 3.1 mm to 4.0 mm were 50%, between 4.1 mm to 5.0 mm were 15%, the ones above 5, 0 mm were only 5%. Conclusion Labbe vein of single and doubles, besides the diameter above 3ram can be used to reconstruction after mutilation,which profit to the operation and reduce the complications.
