Aim:The aim of the present study was to determine the normal distances between the origins of the major branches of the abdominal aorta, and their distances to the aorta at the diaphragmatic region and iliac bifurcation on multidetector computed tomography (MDCT) angiography in pediatric patients.
Materials and Methods:The MDCT angiography scans obtained from 245 children aged between 0 and 18 years (mean age±standard deviation, 8.48±5.14 years) were retrospectively re-evaluated. The distances between the origins of the celiac trunk (CTR), superior mesenteric artery (SMA), right renal artery (RRA), left renal artery (LRA), and inferior mesenteric artery (IMA) were measured. The distance measurements between the aorta at the diaphragmatic region, iliac bifurcation, and the origins of the major branches (CTR, SMA, RRA, LRA, IMA) were performed as well.
Results:The distances between the abdominal aorta and its branches were reported to vary in the age groups. All the distance measurements increased significantly with increasing age (p<0.0001). The distances between the aorta at the diaphragmatic region and the origins of the major branches were significantly higher in girls (p<0.05). The origin of the RRA was higher than the LRA in 51.8% of the study population.
Conclusion:This study is the first to provide data on the distances between the abdominal aorta and its branches in children. The present results may contribute to enhance the efficacy and safety of the endovascular and surgical procedures in the abdominal region.
