摘要
1.我们在41具成人尸体计82例的腰部交感干解剖中,发现腰交感节的数目变化在2—6个之间;其中拥有三个节者最多,共38例,占46.3%。其次为四个节,计22例,占26.8%。在各个节中,以第五腰节最恒定,其次为第二腰节。两干形态对称的在腰部很少见到。2.腰部交感干节一般均位于同数椎骨与下位椎骨之间。3.相邻的两个或三个节可相互合并成一个体积较大的节。左右两干合并节共有28个,占总节数10.2%,其中以GL_(2-3)合并次数最多。4.有时除交感于节以外,尚可见到在交通支或交感根上存有小的副节,共发现27个副节,其中有21个存在于下腰部。5.腰交感干在不同腰椎平面可发生干分裂现象,在82例中有20干分裂为两条或两条以上。6.自每个节发出的交通支可朝向上、下及水平方向。GL_(1)及GL_(2)的支以上下为多,GL_(3)的支以向下及横行为多,GL_(4)及GL_(5)的支多向下,每个节连接支的数目为0—6条。7.每个腰神经接受的交通支为1—5条,其中以接受两支者为多见。8.文中讨论了有关腰交感神经截除的解剖学问题。
Eighty-two dissections of the lumbar sympathetic chain on 41 cadavers of Chineseadults were studied.It was found that the number of ganglia varies from 2--6.Themost common number is three ganglia,which was found in 38 dissections(46.3%),thenext common number is four ganglia,present in 22 dissections(26.8%).The symmetrical arrangement of the ganglia on both sides is uncommon.The loca-tion of the lumbar sympathetic ganglia with their associated vertebral bodies is also ofimportance.They usually overlie the vertebral bodies of the same number.A ganglionis present more frequently at the level of the body of the fifth lumbar vertebra than atany other vertebra.This was found in 69 out of 82 dissections.Variations in the number of ganglia may be accounted for by the fusion of two ormore ganglia into one large ganglion and the latter is connected with multiple spinalnerves.The fused ganglia found on both sides were 28(10.2%),among which the fusionof GL_(2)and GL_(3)is most common.The direction of the communicating rami of individual ganglion varies greatly;theymay run either cranially,caudally or transversely.Therefore,the identification of anindividual ganglion by the direction of its rami is unreliable.The number of rami ofeach ganglion varies from zero to six,most of them having two rami.This was foundin 82 out of 248 ganglia(33%).Each lumbar spinal nerve receives 1--5 commnunicatingbranches,the upper two nerves mostly have two rami and the lower three nerves haveone only.
