Abstract

The location and the variations of the iliolumbar artery are very important for surgeons, since it is used as a feeding pedicle in bone flaps and as it has an injury risk after a pelvic trauma or regional operations. The present study was carried on 25 sagittal sections of male and female pelvises. The variations in the origin of ILA were noted. The length of ILA was measured from its origin up to its branching point. The distances from it point of branching to the midpoint of sacral promontory and the bifurcation of CIA were measured. The relation of obturator nerve with the ILA was also observed. Statistical analysis was carried out using SPSS version 16. The ILA originated from the posterior division of IIA in 22 specimens whereas in 3 cases it originated directly from the trunk of IIA. The length of ILA ranged from 0.8 to 2.5cm in males and 0.5 to 2.1cm in females. Unpaired t test showed significant difference in the means between males and females (p<0.05). The obturator nerve was found to be posterior to the ILA in all the specimens. Knowledge of the variations and morphometry of the ILA in relation to various anatomical landmarks may help the surgeons to minimize the postoperative complications.
