【摘要】：目的通过三维CT血管成像(three-dimensional computed tomographic angiography,3DCT-A)描述臀上动脉(superior gluteal artery,SGA)的位置及解剖形态。方法纳入114例(228髋)患者的3DCT-A数据做以下研究:(1)观察SGA的显影情况;(2)观察SGA的起始、分支及走行特点;(3)定义SGA盆外部分主干为:出盆点到深支止点或折弯点(当深支为1支时)的一段SGA,测量其长度并进行不同性别间的比较;(4)测量SGA盆外部分主干到骨盆骨性标志(髂后上棘、坐骨大切迹起点、坐骨棘)、骨性标志间连线(坐骨棘与髂结节间)的距离,并进行不同性别间的比较。结果 (1)94例患者的SGA显示清晰;(2)所有患者的SGA均来源于髂内动脉;(3)28髋的SGA在出盆前近出盆处发出分支;(4)SGA出盆点到坐骨大切迹起点的距离、到坐骨棘的距离在男女患者间均存在统计学差异;(5)SGA盆外部分主干与髂结节和坐骨棘间连线成近似平行关系。结论通过3DCT-A了解SGA的位置及解剖形态,能为预防SGA的医源性损伤提供帮助。
[Abstract]:Objective to describe the location and anatomic morphology of superior gluteal artery by three-dimensional computed tomographic angiography (3DCT-A). Methods the 3DCT-A data of 114 patients (228 hips) were included in the following study: 1) to observe the development of SGA and 2) to observe the onset of SGA. The characteristics of branch and walk are as follows: the main stem of the outside part of SGA is a segment of SGA from the point of exit of basin to the stop point of deep branch or bend point (when the deep branch is 1 branch), the length of SGA is measured and the comparison between sexes is made. The main trunk of the outside part of SGA is measured. To the pelvis and pelvis (posterior superior iliac spine, The distance between ischium and iliac tubercle, and the distance between ischial spine and iliac tubercle were compared. Results the SGA of 94 patients was clear. The SGA of all the patients was from the distance from the origin of SGA of 28 hips of the internal iliac artery to the origin of the great incision of the ischium from the point of origin of the SGA in the proximal part of the pelvis before the exiting of the pelvis and the origin of the great notch of the ischium. There was statistical difference between male and female patients in the distance from sciatic spine to sciatic spine. There was an approximate parallel relationship between the main trunk of SGA and iliac tubercle and sciatic spine. Conclusion 3DCT-A can help to prevent iatrogenic injury of SGA by knowing the location and anatomical morphology of SGA.
