lumbar arteries造句

• Methods : anatomic observation and blood vessel casting on 20 cadaveric specimens , as well as spinal cord angiography on 9 adults were taken to analyze medullary arteries and its anastomosis with the intercostal arteries or lumbar artery pertinent to thoracolumbar spinal surgery
  方法： 20俱尸体运用解剖、血管铸型及9例成年人常规进行超选择性脊柱脊髓血管造影等方法，对脊柱脊髓血管应用解剖较系统地研究，了解脊柱脊髓血供及代偿通路。
• Conclusions : radiculomedullary arteries would not be damaged if intercostal arteries are deligated at the lateral of transversocostal joint or beyond 1cm of the caput costaes on anterior approach . the distance between two adjacent intercostal or lumbar arteries provide a safe window through which a herniated thoracic disc maybe approached . it indicates the least injury of vessels in osteotomy via the posterior approach in the middle of arcus vertebrae and vertebral body
  结论：脊柱前路矫形应在根髓动脉分支前，结扎多个节段血管，脊髓血供可以通过后方代偿，能避免累及脊髓根髓动脉产生脊髓损伤；侧前入路应在根髓动脉分支后，经胸、腰段毗邻的动脉之间，椎间盘切除或椎间隙减压伤及根髓动脉出现脊髓损伤机率最小。
