肋间后动脉

目的评价多层螺旋CT（MSCT）对肋间后动脉显示的价值。

Objective To assess the ability of contrast-enhanced multislice helical computed tomography ( MSCT ) to depict the posterior intercostal artery ( PICA ) .

第11肋间后动脉在腋后线外径为1.7mm，入肌点距腋后线长为13.1cm；

The 11th posterior intercostal artery was 1.7 mm in diameter at posterior axillary line .

结果：①在第5~9肋间后动脉，侧副支起始处距椎体侧缘的距离平均为（2.3±0.3）cm；

Results : ① The average distance from the start point of collateral branch to the rim of vertebra were 2.3 ± 0.3 cm in the 5th - 9th intercostal space .

ICBA主要起自第3及第4肋间后动脉（87.40%）。

ICBA were mainly arised from the third and fourth right posterior intercostal arteries ( 87.40 % ) .

但第4、5、6肋间后动脉也可考虑选用。

But the fourth , fifth and sixth posterior intercostal arteries could be used as well .

结论：①第5~9肋间后动脉在靠近椎体侧缘附近就已发出了侧副支；

Conclusions : ① The posterior intercostal arties give off the collateral branch near the rim of vertebra .

后髓动脉起始情况分3型10亚型，其中后髓动脉与前髓动脉由同一肋间后动脉发出仅34支（13.5%）。

Only 34 ( 13.5 % ) posterior medullary arteries with anterior medullary arteries branch from the same intercostal arteries .

目的：为左侧肋间后动脉冠状动脉搭桥术提供解剖学基础。

Objective : To provide anatomic basis for coronary artery bypass grafting ( CABA ) by left posterior intercostal artery ( LPIA ) .

结果：第1～12胸神经后皮支的伴行动脉为肋间后动脉的背侧皮支。

Results : The posterior cutaneous branches of T 1 12 accompanied by the dorsal cutaneous branches of the posterior intercostal arteries penetrated the corresponding intercostal tissues , and exhibited a segmental and overlapping distribution on the back .

方法：在25侧成人标本上对第5~9肋间后动脉的侧副支进行观测，并对照活体进行比较观测。

Methods : The collateral branch of the 5th - 9th posterior intercostals arteries were observed on 12.5 adult cadaveric specimens ( 25 sides ) . Some relative data were observed on 20 adult volunteers ( 40 sides ) .

77.31%（167/216支）左侧肋间后动脉起于胸主动脉后壁，右侧肋间后动脉起点分别位于胸主动脉后壁、右后壁和右壁，且自上而下渐由右壁向后壁移行。

Most of the left side of PICA ( 77.31 % ) derived from the posterior wall of the aorta , while the origin of the right side of PICA shifted from the right wall to posterior wall from up to down .

上1／2肌腹的血供66.7%来自第11肋间后动脉，33.3%来自旋髂深动脉的髂嵴支；

The upper 1 / 2 of muscle belly was innervated by the 11th intercostal nerves mainly , and nourished by the 11th posterior intercostal artery ( 66.7 % ) or the iliac branch of deep iliac circumflex artery ( 33.3 % ) .
