摘要
对 15具成人尸体的胸腰脊髓 4 39条髓血管进行大体解剖及形态学观察。其中胸髓髓血管 347条(78.7% ) ,腰髓髓血管 92条 (2 1.3% ) ,伴随前根走行 2 0 9条 (4 7.6 % ) ,出现率为 4 0 % ,胸神经前根髓血管出现率明显高于腰神经前根 (P <0 .0 1) ;伴随后根走行 16 1条 (36 .6 % ) ,出现率为 32 % ,胸腰神经后根髓血管出现率差异无显著意义 (P >0 .0 5) ,其它走行部位 6 9条 (15.8% )。由于腰髓血管粗细不等 ,分布不均 ,血管数少 ,走行部位单一和行程较长 ,故临床医生在作椎管手术时 ,应注意保护这些血管以免损伤。
For probing the relationship between the blood supply of spinal cord and spinal disease as well as lumb-lower limb pain,the thoracic and lumbar medullary vases of spinal cord in 15 cadavers were dessected and observed by groos anatomy.The results show that ①439 medullary vases were found,347 medullary vases are in the thoracic among them,account for 78.7% of the total.92 in the lumbar,account for 21.3%;209 medullary vases companied by the ventrad root,account for 47.6%;the rate of appearing is 40.0%,higher in the thoracic than in the lumbar P<0.01,161 memdullary vases companied the dorsal root,account for 36.6%,the rate of appearing is 32%,there is no different significance between the thoracic and the lumbar P>0.05.②The characteristics of the lumbar medullary vases are less in number,not equal in diameter,not well-distributed,less in entering positions and long distance.These suggest that they are one of the anatomical bases of trouble in circulation
