| In cases where the ischiadic artery persists as the main artery of the lower limb the external iliac is usually poorly developed. |
| Inferior to the posterior inferior iliac spine is the greater sciatic notch. |
| Branches of the anterior and posterior divisions or the internal iliac may exchange origins. |
| The iliac blade tapers and thins ventrally so that its ventral surface forms a sharp ridge. |
| The bone can also be taken from several places, commonest being the iliac crest. |
| He or she then slides the guide wire up the iliac artery just past the renal arteries in the aorta on the ipsilateral side. |
