lumbar arteries 中文意思是什麼
-
A wide anastomosis connecting transversely the intercostals arteries can be observed on the thoracic segments, which located on the intervertebral foramen and musculus sacrospinalis nearby, while anastomosis on lumbar segments on iliopsoas muscle and psoas major. 3
胸段毗鄰的肋間動脈吻合主要是椎間孔周圍和骶棘肌內兩處；而腰段還有椎體側面的骼腰肌和腰大肌中的吻合。 -
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俱屍體運用解剖、血管鑄型及9例成年人常規進行超選擇性脊柱脊髓血管造影等方法，對脊柱脊髓血管應用解剖較系統地研究，了解脊柱脊髓血供及代償通路。 -
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
結論：脊柱前路矯形應在根髓動脈分支前，結扎多個節段血管，脊髓血供可以通過後方代償，能避免累及脊髓根髓動脈產生脊髓損傷；側前入路應在根髓動脈分支后，經胸、腰段毗鄰的動脈之間，椎間盤切除或椎間隙減壓傷及根髓動脈出現脊髓損傷機率最小。
