Objectives: Superior gluteal artery (SGA) injury is the severe complication in the posterior approach of the pelvis. The aim of this study is to investigate the running pattern of SGA by using CT angiography.
Methods: We investigated the contrast enhanced CT around pelvis in 30 cases (male;15, female; 15). Both sides of the pelvis were scrutinized, so we gained the data of 60 pelvises. We measured the parameters as follows using 3D-CT workstation; 1) spatial relationship between SGA and top of the greater sciatic notch (GSN). 2) the diameter of the SGA on the GSN. 3) branching pattern of the inferior rami of SGA. 4) distance between inferior rami and posterior column at the superior border of GSN.
Results and Conclusion: SGA went out of the pelvis 9.73mm medial to the top of GSN. The diameter of SGA at the GSN was 3.78mm. Inferior rami of SGA branched from superior rami of SGA in thirty-five cases (58%) and from the main trunk of SGA in twenty-five cases (42%). Seven cases (23%) were asymmetrical. The distance between the inferior rami and posterior column at the superior border of the GSN was 23.1mm. The main trunk and branches of SGA are located within 2cm around GSN. The meticulous exposure and plate application around GSN should be mandatory.
