摘要
目的 为临床椎动脉重建术提供解剖学依据。方法 20具40侧经防腐处理的成人尸体标本观察椎动脉发出方位,颅外部各段的走行及分支情况,测量各段起点的外径、长度。结果 推动脉大部分直接从锁骨下动脉上壁发出,并直行上升,第1段起点的外径左侧为4.35±0.78mm,右侧为3.97±0.56mm,长度左侧为40.1±5.8mm,右侧为39.6±9.3mm,第2段起点的外径左侧为3.56±0.87mm,右侧为3.07±0.52mm,长度左侧为59.1±7.8mm,右侧为60.6±7.3mm,第3段起点的外径左侧为3.06±0.76mm,右侧为2.81±0.66mm,长度左侧为39.2±2.8mm,右侧为40.6±3.3mm。结论 椎动脉颅外部各段测量结果对临床椎动脉重建术有重要应用价值。
Objective To provide anatomical basis for recontructing vertebral artery (VA).
Methods The locations, courses, branches, outer diameters and length of the extracranial segment of VA
were investigated on 40 sides of 20 adult cadaver. Results VA mostly started from the superior wall of sub-
clavian artery and ascending upright, The outer diameter at jumping-off point of VA on the left and right
side were 4.35±0.78mm and 3.97±0.56mm respectively for the first segment; 3.56±0.87mm and 3.07±
0.52mm for the second segment; 3.06±0.76mm and 2.81±0.66mm for the third segment. The length of
VA on the left and right side were 40.1±5.8mm and 39.6±9.3mm respectively for the first segment; 59.1
±7.8mm and 60.6±7.3mm for the second segment; 39.2±2.8mm and 40.6±3.3mm for the third seg-
ment. Conclusion The results of measure of the extracranial segment of VA have important applicable value
to reconstructing VA.
