Abstract:
Objective To provide anatomical basis for elevating iliac tissue flap pedicled on the iliolumbar artery.Methods The course,number,outer diameter and distribution of iliolumbar artery were observed on 13 human cadavers.Results All the iliolumbar artery originated from the internal iliac artery.The iliolumbar artery gave off 2 branches (iliacus branch and lumbar branch) when passing between the obturator nerve and the lumbosacral trunk,posteriorly to the psoas major.The mean distance between origin of the iliolumbar artery and bifurcation point to iliacus and lumbar branches was 7.1 (7.1 ± 0.5) cm.The iliacus branch divided into two branches:one artery curved forward and anastomosed with the iliacus branch of deep circumflex iliac artery; the other artery supplied the tissue around the posterior superior iliac spine.The lumbar branch supplied the psoas major and the quadratus lumborum.Conclusion The iliolumbar artery and the iliacus branch is one of the most constant and reliable vessels supplying the iliac bone,and can be used as the pedicle of free or pedicled iliac tissue flaps.
