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。
The gross anatomy and morphology of 419 medullary vessels in thoracolumbar spinal cord of 15 adult cadaveric eyes were observed. There were 347 (78.7%) of the medullary and medullary vessels, 92 of the medullary and medullary vessels (21.3%), 290 accompanying the anterior root (40.6%) and the incidence of 40% The incidence of vascular was significantly higher than that of the anterior lumbar nerve (P <0.01). With the subsequent root walking 16 1 (36.6%), the incidence rate was 32% Significant significance (P> 0.05), other walking sites 69 (15.8%). As the uneven thickness of the spinal cord blood vessels, uneven distribution, fewer blood vessels, walking a single stroke and longer, so clinicians for spinal surgery, should pay attention to protect these vessels so as not to damage.
