摘要: 目的    比较仰卧位、俯卧位及侧卧位时,腹主动脉和下腔静脉在腰椎各椎间隙水平的位移变化和腰大肌厚度及位移变化,确定经侧路进行腰椎融合术的安全工作区。  方法    15名志愿者在3种体位接受腰椎磁共振检查,记录L1/2~L4/5椎间隙水平腹主动脉和下腔静脉的位置、腰大肌的厚度及位移情况并进行比较。  结果    相同节段不同体位下腔静脉分布相似。而在L1/2~L3/4水平,相较于仰卧位,腹主动脉在侧卧位和俯卧位部分向前方移动至椎体前缘。相同节段不同体位腰大肌厚度存在差异(L2/3 A区,L3/4 A区、IV区和P区,L4/5 II区和IV区)(P<0.05)。不同节段腰大肌前移距离存在差异,在L1/2水平,俯卧位(-7.53±3.30)mm及侧卧位(-7.25±3.96)mm的前移距离大于仰卧位(-10.90±3.31)mm,P=0.012;在L2/3水平,侧卧位的前移距离(-0.12±5.59)mm明显大于仰卧位(-5.03±2.49)mm和俯卧位(-3.38±3.99)mm,P=0.009;在L3/4和L4/5水平未见明显差异。  结论   右侧卧位在L1/2、L2/3选择I、II区穿刺是安全可行的;L3/4、L4/5水平可以选择II区穿刺。

Abstract:  Objective    To explore the changes of the abdominal aorta and vena cava in different lumbar intervertebral space levels in supine, prone, and lateral positions, and the thickness and displacement of the psoas muscle were noted as well to define the safe working zone for lateral lumbar interbody fusion. Methods    Fifteen volunteers underwent lumbar magnetic resonance imaging (MRI) examinations in different positions (supine, prone and lateral positions). The position of the abdominal aorta and inferior vena cava, the thickness, and displacement of the psoas major muscle at each intervertebral space level (L1/2~L4/5) on MRI were recorded and compared as well.    Results    In the same segment, the distribution of the inferior vena cava in different positions was similar. However, compared with the supine position, the abdominal aorta moved anteriorly to the anterior edge of the vertebral body in the lateral and prone positions at L1/2~L3/4 levels. There were differences in the thickness of the psoas muscle between different body positions in the same segment (L2/3 A zone, L3/4 A zone, IV zone and P zone, L4/5 II zone and IV zone) (P<0.05). In addition, there were differences in the anterior displacement of the psoas muscle between different segments. At the L1/2 level, the forward movement distances of the prone (-7.53±3.30 mm) and lateral positions (-7.25±3.96 mm) were significantly greater than that of the supine position(-10.90±3.31 mm) (P=0.012). At the L2/3 level, the forward displacement of the lateral position (-0.12±5.59 mm)was significantly greater than that of supine (-5.03±2.49 mm) and prone (-3.38±3.99 mm) positions (P=0.009). There was no significant difference in the L3/4 and L4/5 levels.    Conclusions    For right lateral position, it is safe and feasible to select zone I and II for puncture in the L1/2 and L2/3 levels. And zone II is suitable to puncture in L3/4 and L4/5 levels.
