选择性脊髓动脉造影的应用解剖

Applied anatomy in the selective angiography of spinal cord

用血管造影和读数显微镜对６３例成人尸体起源于肋间、腰动脉的前根髓动脉的支数，起始动脉口内径、位宜及分布做了观察。结果表明：前根髓动脉的支数在男性个体为２．２支，女性为３．０支，男、女性之间有显著性差异（ｐ＜０．０２５）．发出前根髓动脉的肋间动脉起始口内径，男性平均为１．５７ｍｍ，女性为１．４２ｍｍ；发出前根髓动脉的腰动脉起始口内径，男性平均１．６２ｍｍ，女性为１．８９ｍｍ。对上述动脉的位置和分布做了分析，为提高选择性脊髓动脉造影的成功率提供了可靠的解剖学依据。

he number,location,distribution and orifice diameter of the anterior radiculomedullary ar-teries(ARMA),which rise from the intercostal and lumbar arteries,were observed in detail by an-giography and reading microscopy in 63 adult chinese cadavers,The results showed that the aver-age ARMA numbers are 2.2 in male and 3.0 in female,the orifice diameters originning from theintercostal artery are 1. 57 mm in male and 1.42 mm in female,while the orifice diameters fromthe lumbar artery are 1. 62 mm in male and 1.89 mm in female. The anatomic study furnishes reli-able evidence for raising the successful efficiency of selective angiography of spinal cord.
